General Overview
HPMC powder 2208 medium-viscosity construction grade is the most widely used dry-mix mortar additive. As a reliable hpmc supplier, our hydroxypropyl methylcellulose delivers balanced thickening and water retention, effectively improves mortar workability and anti-sagging ability, suitable for most conventional dry-mix systems.
Core Product Advantages
1. Balanced Thickening & Water Retention: Strikes an ideal balance between water retention and workability, making it a universal choice for most dry-mix mortars without compromising construction efficiency.
2. Prolonged Open Time: Effectively extends the operation and adjustment window of mortar, adapts to large-area construction and reduces material waste and rework.
3. Improved Sag Resistance: Endows mortar with ideal structural viscosity, prevents tile adhesive from slipping and sagging, and ensures tiling accuracy.
4. Stable Batch Quality: Strict quality control throughout the whole process ensures small fluctuations in viscosity and substitution degree, eliminating frequent formula adjustments.
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.
