First prepare a 5% calcium chloride aqueous solution: Weigh 50 g of anhydrous calcium chloride with a 1% balance, add 950 ml of water to shake well, and set aside. In a 10 ml graduated test tube, use a dropper to add 5 ml of emulsion, and then add 1 ml of 5% calcium chloride solution. Pay attention ... read more
The emulsion for architectural coatings should develop in the direction of ultra-durability and versatility. Such as actively researching and developing fluorine-containing emulsions, acrylic silicone emulsions, vinyl acetate-tertiary carbonate copolymer emulsions, room temperature cross-linking emu... read more
As the base material of emulsion paint, the synthesis technology has made rapid progress. Different new types of emulsions are synthesized by different polymerization methods, which can meet the new requirements of the continuous development of architectural coatings. (1) Soap-free emulsions use pol... read more
Most of the emulsions used in architectural coatings are non-crosslinked thermoplastic emulsions. Usually classified according to its monomer composition. The main varieties are:(1) Vinyl acetate homopolymer emulsion (vinegar homogenized emulsion white latex);(2) Vinyl acetate-maleate copolymer emul... read more
Interpenetrating polymer is a kind of high-quality special polymer. At least one of its composition is a cross-linked structure. It achieves the effects of "forced mutual solubility" and "molecular synergy" at the molecular level. The capacity is better. Add polyether glycol isocyanate, chain exte... read more
