Product properties
1. Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3. Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4. Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
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.

Cement-based mortar
1. Improve the uniformity, makes easier to coating the mortar, and improve the vertical flow resisitance simultaneously. Enhance the liquidity and pumpability, so as to improve the work efficiency.
2. High water retention and prolong the working time of mortar, improve work efficiency, and help to make high mechanical strength in mortar freezing period.
3. Control the air infiltration, thus eliminating the coating microfissuring, to make the ideal smooth surface.
Gypsum mortar and gypsum products
1. Improve the uniformity, makes easier to coating the mortar, and improve the vertical flow resisitance simultaneously. Enhance the liquidity and pumpability, so as to improve the work efficiency.
2.High water retention, to prolong the working time of mortar, and help to make high mechanical strength in mortar freezing period.
3. By controlling the mortar uniform thickness, to make the high quality surface coating.
Masonry mortar
1. Enhance the adhesiveness to masonry surface and the water retention, to improve the strength of the mortar.
2. Improve the lubricity and plasticity to improve the workability. Using cellulose ether to enhance mortar is easier to consdruct and save time, and improve the cost-effectiveness.
3. There is high water retention type in particular, applying to high water-absorbing.
Bricks Plate joint sealing material
1. Good water retention, can prolong open time and improve the work efficiency. High lubricity, makes it easier to use and smooth-going.
2. Improve the shrinkage resistance and crack resistance, to improve the surface quality.
3. To provide the smooth and uniform texture, and make the adhesiveness of joint surface stronger.
Ceramic tile adhesive
1. Make it easier to blend the dry mixture and no clumps , thus saving the work time. And the faster and more effective construction can improve the workability and reduce the cost.
2. By prolonging the open time, to improve the tiling efficiency and provide excellent adhesiveness.
3. There is special development model of high slip resistance.
Self-leveling flooring
1. Provide the viscosity, can be used as anti-sludging agent.
2. Enhance the liquidity and pumpability, so as to improve the flooring efficiency.
3. Control the water retention, thus greatly reducing cracks and shrink.

Water-based paint and varnish remover
1. By preventing solid precipitation and prolong the storage period.There is good compatibility with other components and has high biological stability.
2. Dissolve fast and without clumps, helps to simplify the mixing process. Cold water dispersion model, can mix faster and more convenient and no clumps.
3. Produce favorable flow characteristics, including low splashing and good leveling, to ensure fine surface finish and prevent the oil paint flow.
4. Strengthen the viscosity of water-based and organic solvent paint remover, to make the paint remover not outflow from the workpiece surface.
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.
