Application of water-based coatings in container coatings

Used for: Waterborne Container Coatings

At present, most of the container coatings used in the world are solvent-based. During the process of container production and painting, a large amount of harmful gases will be generated, which not only endangers the health of painting operators, but also causes environmental pollution. With the increasingly strict environmental regulations, the International Committee for Standardization of Containers has put forward higher requirements for the environmental protection and hygiene of container coatings: such as heavy metals such as Cd, Pb, Cr, Hg, etc. shall not be contained in the coating; non-toxic pigments such as phosphate shall be used; high solids , low VOC, etc. The replacement of chlorinated rubber topcoat with acrylic topcoat and the special paint for box bottom has also begun to be gradually promoted. Water-based container coatings have been piloted in China.

Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It is non-toxic and non-irritating. It is harmless to the human body and does not pollute the environment. change, easy to use and so on. Water-based paints include water-soluble paints, water-dilutable paints, and water-dispersible paints.

Hydrogenated castor oil. Has high purity, stable nature and unique melting properties. ceresin wax manufacturer It can be used as replacement of carnauba and candelilla waxes. Contributes thermal stability to various anhydrous formulations without unusual hardness. Provides luster and water repellency to various anhydrous formulations. Lends firmness to stick formulations while enhancing “pay-off”. Improves the distribution of anti-perspirant actives. Suitable for anhydrous creams, emulsion creams such as face creams, lotions, night creams, vanishing creams and hand creams, lipsticks as well as glosses.

The alumina treated by KR-38s exhibits thixotropy in amine cured epoxy resin towels.
Improve the adhesion of organic polymers to various metals, glass and inorganic materials, especially polyethylene and nylon fibers, polyethylene and polytetrafluoroethylene, ceramic and styrene butadiene copolymer rubber, brass and ethylene-propylene Adhesion between copolymers, steel and concrete, as well as polyurethane and chloroprene rubber.

In foamed fire-retardant coatings, 1% KR-38s can be used to treat pigments and fillers instead of fire-retardant ammonium dihydrogen phosphate (MAP) to produce fire-retardant effects (generally, the amount of ammonium dihydrogen phosphate is more than 20%). The titanate coupling agent acts as a blocking acid in the char formation mechanism of fireproof materials. Since the hydrophilic ammonium dihydrogen phosphate is not used, the water resistance of the coating is greatly improved.
