Main application
1. Construction industry: with good thixotropy and adhesive, so that mortar can be pumped. As binders in plaster, gypsum material, putty powder or other materials, it has the function of thixotropy and coagulation, which can improve and extend the operational time of painting. As the adhesion enhancer for bonding tiles, marble, plastic decoration, it can reduce the dosage of cement. With water retention, it makes the slurry not dry too fast and cracked, increasing the strength after hardening.
2. Ceramic industry: widely used as a binder in the manufacture of ceramic products.
3. Paint industry: as a thickening agent, dispersing agent and stabilizer in the paint industry, and have a good compatibility in water or organic solvents, also can be used in paint remover.
4. Ink printing,Plastic, PVC, Textile and others.
Packing and Storage
Standard Packing: In 25kg bags out HDPE bags with inner plastic bags.
Store it in a cool, dry place below 30degree and protected against humidity and pressing, since the goods is thermoplastic, storage time should not exceed six months.
