The construction chemicals sector has delivered a cluster of useful market signals this October: new forecasts for hydroxypropyl methylcellulose (HPMC) and hydroxyethyl methyl cellulose (HEMC), an expanded European distribution partnership for cellulose ethers, and updated redispersible polymer powder (RDP) growth projections. Taken together, the data paints a picture of steady, structurally supported demand for dry-mix mortar additives through 2035 — even as input costs, feedstock volatility, and regulatory pressure reshape how formulators buy and blend these materials.
New Distribution Move Highlights European Cellulose Ether Supply Strategy
In early October 2026, KRAHN Chemie announced an expanded partnership with Nouryon, becoming a distributor of Nouryon’s cellulose ethers, carboxymethyl cellulose (CMC), cellulose-based polymers, and selected surfactants in Germany, Austria, and Switzerland. The move covers coatings and construction markets, where these rheology modifiers are critical to water-based formulations.
Two products stand out for mortar and render formulators:
- Bermocoll EHEC (ethyl hydroxyethyl cellulose) and MEHEC (methyl ethyl hydroxyethyl cellulose) — non-ionic cellulose ethers manufactured via a solvent-free process, with Nouryon positioned as the world’s sole manufacturer of these technologies.
- Finnfix and Akucell cellulose-based polymers, rounding out a comprehensive formulation portfolio for construction applications.
The partnership matters for buyers watching supply-chain resilience. After the EU’s anti-dumping investigation into Chinese and Korean cellulose ethers initiated in late September 2026, European distributors are actively consolidating alternative supply routes. Expect more regional qualification activity as tile adhesive and render producers diversify their approved supplier lists.
HEMC: A Niche Market Priced on Formulation Know-How
A Market Research Intellect report updated October 2, 2026 puts the global HEMC market at USD 485 million in 2025, projected to reach USD 750 million by 2035 — a 4.5% CAGR. The report’s framing is instructive: this is a specialty additive business where value concentrates in viscosity control, substitution performance, and technical service rather than raw tonnage.
Key regional shares:
- Asia-Pacific: 46% of global demand, with China as both the largest production center and a major consumption market
- Europe: 27%, supported by a mature renovation sector and sophisticated dry-mix mortar industry
- North America: 17%, driven by repair, remodeling, and ready-to-use compounds
HEMC competes directly with HPMC in tile adhesives, repair mortars, and self-leveling products. Because switching grades requires laboratory screening, pilot mixing, and field validation, approved formulations tend to lock in — which lengthens customer retention and rewards suppliers who can tune water retention and thermal gel behavior to local cement and climate conditions.
HPMC Remains the Revenue Anchor: USD 2.18B to USD 3.91B by 2035
The same research house pegs the combined MC and HPMC market at USD 2,180 million in 2025, growing to USD 3,910 million by 2035 at a 6.0% CAGR. HPMC alone accounts for roughly 81% of 2025 value. Construction remains the largest volume outlet, with tile adhesives, renders, and repair mortars anchoring demand, while pharmaceuticals contribute the higher average selling prices.
These figures align with the broader IndexBox cellulose ether thickeners outlook (October 3, 2026), which forecasts 4–5% volume CAGR from 2026 to 2035, with standard HPMC prices expected to hold in the USD 4.0–6.5 per kilogram range (FOB ex-China). China continues to supply an estimated 50–55% of global tonnage, though India, the US, and Europe are steadily adding capacity to de-risk supply chains.
RDP Forecasts Converge on Solid Growth
On the polymer side, several new RDP estimates landed recently, and while the absolute numbers vary by methodology, the direction is consistent:
- Market Lens IQ: USD 1.61 billion (2024) growing to USD 3.17 billion by 2033 at a 7.8% CAGR, with Asia-Pacific holding 45% share and VAE chemistry representing 52% of revenue.
- Grand View Research (via industry coverage): USD 851.3 million estimated for 2026, reaching USD 1,519.6 million by 2033 at an 8.6% CAGR, with VAE holding a 59.2% revenue share in 2025.
- Research and Markets: a more conservative USD 1.1–1.5 billion for 2026 with 4–5% CAGR through 2031, emphasizing insulation-driven demand from Europe’s Renovation Wave and the EPBD.
Tile adhesives remain the largest single RDP application (roughly 35% of demand), followed by plasters and renders — together over 60% of application consumption. The fastest-growing application is insulation systems, at a projected 9.6% CAGR, as External Thermal Insulation Composite Systems (ETICS) adoption accelerates with global energy-efficiency mandates.
Price Watch: VAE RDP Feedstock Pressure Easing After a Volatile Q2
Procurement teams should note the VAE redispersible powder price dynamics tracked through 2026. Q2 2026 saw quarterly index increases of 10–14% across major markets — India up 14% on limited vinyl acetate monomer (VAM) availability and higher import costs, the US up 12% on freight and insurance, and China, Taiwan, and Vietnam each up 10% on feedstock and production costs. By June, prices softened as VAM supply improved and logistics pressure eased.
The lesson for buyers: VAE RDP pricing is a chain of linked variables — VAM availability, ethylene economics, upstream operating rates, and freight. Monitoring monthly supplier quotations and feedstock markets remains essential before committing to fixed-price supply contracts.
Formulation Economics: Additives Are Small by Weight, Large by Cost
A 2026 dry-mix formulation trends analysis offers a striking number: chemical additives represent a modest fraction of total batch weight but up to 60–70% of raw material costs in tile adhesives, skim coats, and self-leveling underlayments. That explains three shifts gaining traction among producers this year:
- Medium-viscosity over ultra-high-viscosity HPMC: moving from 150,000–200,000 mPa·s grades to modified 40,000–70,000 mPa·s grades maintains water retention at or above 98% while improving workability and lowering dosage.
- Rheology synergy: replacing 10–15% of primary HPMC dosage with high-purity hydroxypropyl starch ether cuts cost per ton while enhancing thixotropy and sag resistance.
- Direct factory sourcing: bypassing distributor markups of 20–35% where volume justifies it — a strategy now under scrutiny given the EU trade investigation.
For exporters selling into hot climates, high-hydroxypropyl modified HPMC grades that push thermal gelation points above 65°C continue to command premiums, helping mortars meet the 30-minute open time requirements under ISO 13007 / EN 12004 at jobsite temperatures exceeding 40°C.
What This Means for Additive Buyers in Q4 2026
The October data supports three practical conclusions. First, structural demand is intact: dry-mix penetration, renovation activity, and ETICS growth are insulating cellulose ether and RDP demand from housing cyclicality. Second, supply diversification is accelerating — European distribution consolidation and capacity additions in India and Southeast Asia are direct responses to trade-policy risk and feedstock volatility. Third, formulation efficiency is the new margin lever: with standard-grade prices stable but energy and pulp costs volatile, the producers who win are those optimizing dosage and grade selection rather than simply chasing the lowest price per kilogram.
