Gerneral Overview
High viscosity hpmc hydroxypropyl methyl cellulose 2208 is a special thickening additive for thick-layer dry-mix building materials. Our hpmc powder provides high thickening efficiency and excellent anti-sagging performance, effectively stabilizes mortar structure and avoids sagging during thick-layer construction.
Core Product Advantages
1.High Thickening Efficiency: Achieves ideal thickening effect at low dosage, reduces the consumption of other additives and optimizes overall formula cost.
2. Outstanding Sag Resistance: Effectively supports aggregates during thick-layer putty or insulation mortar construction, prevents falling off and ensures uniform thickness.
3. Long-lasting Water Retention: Higher molecular weight delivers stronger water-locking capacity, maintains moisture for a long time in dry environments and reduces later dry shrinkage cracking.
4. Good Film-forming Property: Improves surface compactness of mortar, reduces water seepage risk and enhances the durability of mortar layer.
Product Specifications
Construction-grade Hydroxypropyl Methyl Cellulose (HPMC) 2208 (modified high-temperature resistant grade) is a specialized core additive for dry-mix building materials optimized for high-temperature construction environments. It delivers excellent high-temperature water retention and stronger thermal stability, can greatly extend the open time and adjustable time of mortars in extremely hot conditions, and prevent rapid drying skinning and early cracking; it improves system workability and sag resistance, reduces application resistance, maintains stable performance over a wide pH range, and has good compatibility with cement, gypsum and various construction additives. With easy powder dispersion, fast dissolution and stable batch quality, it is particularly suitable for dry-mix building material systems such as tile adhesives, interior and exterior wall putties, plastering mortars, self-leveling compounds, joint fillers and exterior wall insulation mortars in summer high-temperature construction and dry-hot climate regions.
Key Technical Specifications
Application Scenarios
1. Thick-layer Putty: Delivers strong thickening and anti-sagging performance, ensures no material sagging during thick-layer scraping.
2. Insulation Bonding Mortar: Improves bonding strength and system stability, prevents insulation board from slipping.
3. Anti-cracking Render Mortar: Enhances mortar toughness and reduces drying shrinkage cracking.
4. Decorative Mortar: Improves shape retention and enriches decorative effects.
