The construction chemicals industry enters August 2026 with three telling signals from the last week of July. Polycarboxylate superplasticizer feedstock prices have accelerated sharply on the back of an oil-and-ethylene rally triggered by renewed Middle East tensions. Sika, the world’s largest pure-play construction chemicals supplier, raised its full-year growth guidance after delivering 4.0 percent local-currency revenue growth in the first half, despite a 5.5 percent negative currency drag from a strong Swiss franc. And India’s INR 24,436 crore construction chemicals market is attracting unprecedented global capital — Saint-Gobain alone has committed a fresh USD 1 billion over five years — even as the share of cement actually receiving chemical treatment slips. Read together, these threads describe an industry that is pricing inputs geopolitically, competing for share rather than volume, and bifurcating between high-specification and cost-sensitive demand pools.

PCE Feedstock Costs Step Higher on Middle East-Linked Oil Rally

East China polycarboxylate superplasticizer (PCE) monomer costs climbed again in the week ending 23 July 2026, the steepest one-week move of the current cycle. According to SCI99 weekly data and Mysteel daily assessments, ex-works HPEG reached RMB 8,100–8,300 per metric ton and EPEG followed close behind, both up roughly RMB 600 per ton week-over-week. Non-ionic surfactants for the same downstream chain cleared RMB 13,200–13,300 per ton (+2.71 percent week-over-week), and ethanolamine finished at RMB 7,800–8,000 (+4.64 percent). All three products now sit at or near their highest quotes since 2024.

The driver this time is upstream rather than supply-side. Spot ethylene oxide (EO) in East China closed 23 July at RMB 7,000 per ton, up 7.69 percent week-over-week, on the back of a 3–5 percent jump in Asian ethylene spot prices and a 4–6 percent rise in international crude. SunSirs attributes the move to three reinforcing factors:

• Cost-side pressure: Repeated US-Iran geopolitical flare-ups have pushed crude and naphtha higher, lifting Asian ethylene and tightening EO producer margins.
• Concentrated EO unit maintenance: Shenghong, Luxi, Wuhan Petrochemical, and a fresh Yangzi Petrochemical turnaround have kept industry operating rates subdued, leaving merchant supply tight.
• Co-product MEG diversion: Mono-ethylene glycol port inventories in East China have fallen to multi-year lows, prompting co-producing facilities to prioritize higher-margin MEG, shrinking merchant EO further.

The market is treating this as a corrective rebound rather than a sustained uptrend. SunSirs expects Gulei and Wuhan EO units to restart in early August, and downstream construction-chemical and textile demand remains in its traditional seasonal trough. SunSirs expects late-July through August pricing to hold near current levels, with cost-side floors preventing any sharp downside but with limited room for further gains.

What this means for buyers and formulators:

• Spot liquid PCE quotes will reset higher through August as producers pass through the monomer rally. Buyers holding short-cycle contracts are most exposed.
• Long-term supply agreements with backward-integrated monomer producers — Sobute, Satellite, BASF, Sika — are increasingly valuable as feedstock volatility compounds.
• The PCE ether market is forecast to reach USD 13.6 billion by 2033 from USD 9.2 billion in 2026 at a 5.7 percent CAGR (Persistence Market Research). Margin recovery through 2027 will hinge on how efficiently producers integrate EO and methacrylic acid chains.

Sika Raises Full-Year Guidance After 4.0 Percent Local-Currency H1 Growth

Sika, the Baar-based specialty chemicals leader, posted 2026 half-year results on 28 July that demonstrate why scale and pricing discipline still matter in a flat market. The headline numbers:

• Net sales: CHF 5,589.8 million (reported -1.5 percent), +4.0 percent in local currencies, organic growth +2.9 percent, acquisition effect +1.1 percent
• EBITDA: CHF 1,063.0 million, EBITDA margin 19.0 percent (+10 basis points year-on-year)
• Material margin: 55.7 percent (+60 basis points year-on-year)
• Net profit: CHF 552.1 million (vs CHF 554.4 million in H1 2025)
• Operating free cash flow: CHF 139.6 million (vs CHF 181.9 million)

The Swiss franc surged roughly 5 percent against major currencies during the half-year on safe-haven flows linked to Iran-related tensions, which is why reported sales shrank even as local-currency sales grew 4.0 percent. The currency drag was 5.5 percent. Regional results were mixed:

• EMEA: +7.7 percent local-currency growth, +2.4 percent acquisition contribution, the strongest region
• Americas: +2.9 percent local-currency growth, supported by Florida and Georgia batching-plant density and the recent Bridgeton, New Jersey mortar plant opening
• Asia/Pacific: -2.0 percent local-currency growth, reflecting Chinese market softness offset by India and Southeast Asia expansion

Sika’s response was decisive. The company raised its 2026 sales-growth guidance in local currencies to 3 percent to 6 percent, up from the prior 1 percent to 4 percent range. EBITDA margin guidance was tightened to 19.0 percent to 19.5 percent from the earlier 19.5 percent to 20 percent ceiling, with the lower end reflecting both prudent currency hedging and the expected cost-side pressure from the EO rally described above. The Fast Forward efficiency program remains on track for CHF 80 million in 2026 savings, and the Benelux regional plant opened in June 2026 in Ham, Belgium is now live.

CEO Thomas Hasler framed the result as confirmation that Sika is gaining share in strategically important growth segments — infrastructure, data centers, and high-rise commercial — even as the broader construction market stays muted. The Ham, Belgium and Bridgeton, New Jersey plants, plus the recent acquisition of Akkim (closing Q3 2026, CHF 220 million trailing sales), give the company concrete answers to investors asking how it intends to outgrow its end markets.

India Construction Chemicals Market: Capital Surge Meets a Penetration Paradox

India’s construction chemicals market generated INR 24,435.88 crore in revenue (approximately USD 2.9 billion) in FY 2026, up from INR 18,300 crore in FY 2023, a 10.12 percent CAGR according to Makreo Research. The forecast period FY 2026-2031 calls for a more measured 7.37 percent CAGR, bringing the market to roughly INR 35,000 crore by 2031. Within that, concrete admixtures are the single largest segment at 32 percent share, followed by waterproofing systems and repair chemicals.

The capital commitments flowing in are far larger than the underlying growth rate would suggest:

• Saint-Gobain announced in May 2026 a fresh USD 1 billion in capital expenditure over five years for India, on top of the USD 600 million deployed over the prior five. CEO Benoit Bazin is targeting a tripling of the India business within a decade, with capital intensity more than double the group’s average relative to sales — a clear signal that construction chemicals is being treated as a strategic growth engine rather than a mature cash business.
• BASF expanded dispersions capacity at its Mangalore facility in February 2026 to strengthen local supply for construction chemicals, paints, and packaging.
• Henkel introduced Loctite MS 9650, a silane-modified adhesive for industrial bonding, broadening the specification tool kit available to Indian formulators.
• Caldic (Netherlands) partnered with Elkay Chemicals in mid-2026 to bring specialty silicone technology into Indian paints, coatings, and construction formulations through distribution.

Indian-listed players are moving just as aggressively:

• Pidilite Industries, the market’s clearest bellwether, posted FY 2026 revenue of INR 14,600.83 crore with Q4 growth above 15 percent. Management flagged raw material cost inflation of 40 to 50 percent, passed through via calibrated price hikes rather than margin sacrifice.
• Ramco Cements relaunched its construction chemicals division in August 2025 under the unified “Hard Worker” brand, targeting growth from roughly INR 210 crore to INR 2,000 crore within four to five years — a tenfold ambition across a twenty-product portfolio.
• Asian Paints received NCLT approval in March 2026 to merge its polymers subsidiary into the parent, streamlining operations ahead of a higher-specification push.

The penetration paradox. Despite the headline growth, the share of cement actually receiving chemical treatment in India has fallen from 46.45 percent in FY 2023 to 43.95 percent in FY 2025. Two structural factors explain this. First, cost-sensitive segments such as affordable housing under PMAY and rural construction are growing faster than the formal market, dragging down penetration. Second, a large portion of installation work is performed by small, under-trained contractors — a Makreo distributor survey of 400 distributors and 150 applicators across six cities confirms that applicator competence and brand-loyalty at the dealer level remain the real barriers to penetration, not headline market size.

M&A intensity is rising. Recent transactions underline that consolidation is concentrated in technically differentiated segments — waterproofing, admixtures, repair chemicals, and specialty adhesives — rather than across the broader market. The largest deal in the segment is Dorf Ketal’s exclusive negotiations to acquire Italy’s Italmatch Chemicals at roughly USD 1.6 billion, one of the biggest specialty-chemicals transactions involving an Indian buyer. BirlaNu paid around INR 120 crore for Clean Coats (Mumbai) in November 2025 as part of a broader INR 1,300 crore investment program that aims to grow the specialty coatings business tenfold within four to five years. Astral Chemie paid INR 39.11 crore for a 60 percent stake in DSS LLP in June 2026, a backward-integration move into specialty amines and performance additives.

Implications for global suppliers. India is no longer a market where local brand strength alone suffices. Global incumbents are pairing capital deployment with localization — Saint-Gobain is positioning India as a global export hub for glass, gypsum, and construction chemicals — while Indian majors are accelerating backward integration and brand consolidation. The applicator gap remains the structural constraint: companies that can pair technical specification with certified installer networks will capture disproportionate share in the second half of the decade.

Outlook Through August

Three watchpoints for the next four weeks:

• EO and PCE monomer direction. Gulei and Wuhan EO unit restarts are expected to bring merchant supply back online in early August, which could cap the current rally. If US-Iran tensions escalate further, however, crude and ethylene could push EO above RMB 7,500 and pull PCE monomers toward RMB 8,500.
• Q3 pre-announcements. With Sika and BASF both having updated guidance positively, watch for Wacker, Arkema, and GCP Applied Technologies to clarify their exposure to the EO price spike and any signs of margin recovery in concrete admixture lines.
• Indian applicator programs. Saint-Gobain, Sika, Pidilite, and BASF are all expected to expand certified applicator networks and dealer training in H2 2026 as competition for the under-penetrated informal segment intensifies.

For procurement, formulation, and specification teams, the second half of 2026 will reward those who lock in backward-integrated supply, hedge against ethylene-driven PCE volatility, and treat India as a strategic growth market rather than a cost-arbitrage opportunity.
