Gerneral Overview
Long open time hpmc for tile adhesive is a modified hydroxypropyl methyl cellulose for large-area tile construction. Our hpmc powder greatly extends open time and maintains good wettability.
Core Product Advantages
1. Ultra-long Open Time: Significantly prolongs the open and adjustment window, eliminates concerns about adhesive surface drying failure during large-area construction.
2. Long-lasting Wetting Capacity: Maintains wet state of adhesive paste for a long time, ensures full bonding between tiles and base layer, avoids false bonding and hollowing.
3. Large-area Construction Adaptation: Leaves enough adjustment time for construction, improves tiling efficiency and pass rate, and reduces rework.
4. High-temperature Construction Adaptation: Maintains long operation time even in high-temperature environments, eases summer construction pressure.
Product Specifications
Ceramic Grade Sodium Carboxymethyl Cellulose (2000 mPa·s, DS:0.85) is a medium-viscosity high-substitution anionic cellulose ether dedicated to ceramic production. It offers excellent dispersion and suspension properties to stabilize glaze slurry, avoid pigment precipitation and improve glaze smoothness. It strengthens ceramic green body bonding, reduces firing cracking, and features fast dissolution and great compatibility with various ceramic raw materials.
