Low-carbon environmental protection is the mainstream trend of social development, traditional solvent-based coating pollution is serious, in recent years, China's heavy blows to control environmental pollution problems, as well as people's awareness of environmental protection, the coating industry "oil to water" has become inevitable.
All coatings that use water as solvents or dispersing media can be called water-based coatings. The composition of water-based coatings is water-based resin, water, pigment filler, and various auxiliaries. Among them, in addition to resin, filler is a material with a large proportion of coating formulations, and calcium carbonate is one of the most common fillers in the coating industry. To this end, our company for the waterborne coating industry developed a hydrophilic active calcium XFH-618-F3, which has better compatibility, abrasiveness, dispersion, adhesion, stability, and can effectively reduce the viscosity of the system, reduce processing energy consumption, improve production efficiency.
The above is the hydrophilic active calcium XFH-618-F3 technical specifications, the product has:
(1) Strong hydrophilicity, can be quickly mixed into the water-based color paste, reduce the amount of wetting agent, dispersant;
(2) Easy grinding, the initial fineness and final fineness are significantly lower, the grinding efficiency is greatly improved, and the production efficiency is improved;
(3) It can reduce the viscosity of the system, have lower viscosity under high shear and low shear, reduce processing energy consumption, and increase the filling volume and reduce costs;
(4) Uniform dispersion, insoluble precipitation, agglomeration, etc.;
(5) Good storage stability, no water, no coarseness, no precipitation;
(6) Enhance the adhesion of the paint film.
Application of hydrophilic active calcium XFH-618-F3 in aqueous acrylic coatings:
The comparison can be seen: hydrophilic active calcium XFH-618-F3 is faster than ordinary 1500 mesh heavy calcium wetting speed, good dispersion effect, adhesion and storage stability are improved.
