2021-09-25   Pageview:617

White or light yellow solid, easily soluble in isopropanol, soluble in water, and compatible with cationic, non-ionic and amphoteric surfactants. It has excellent penetration, softening, emulsification, antistatic, biodegradability and sterilization properties. This product has good chemical stability, heat resistance, light resistance, pressure resistance, strong acid and alkali resistance.












Traditional thickeners, such as HEC and later developed polyacrylate thickeners, rely on their hydrophilic backbone to form an osmotic gradient in the water phase. Other components in the coating, such as emulsions and pigments, form a water-reducing phase, which ultimately leads to poor leveling, lower gloss and more serious splashing in roller coating after application and film formation. The associative thickener will form a more uniform system, and make the coating film have better leveling and gloss. Comparison of traditional thickeners and associative thickeners.

According to the different molecular structures of associative thickeners, the rheological curve can range from Newtonian to pseudoplastic [89]. The association can be separated by centrifugation, micronized ptfe use and then the remaining aqueous phase is subjected to slurry analysis (L40]. Due to this strong interaction between associative thickeners and other surface-active substances such as wetting agents and dispersing agents [41], two or more thickeners are usually used in combination to compensate for a single variety of thickeners. In this way, additional leveling effects can be obtained [42]. In principle, any water-soluble polymer can be transformed into an associative rheology modifier, which requires the introduction of enough hydrophobic parts into the polymer molecular chain superior. A variety of different types of thickeners that have been developed and commercialized are listed below.
HEUR is a hydrophobically modified urethane ether; HMP E is a hydrophobically modified polyether; HMP AM is a hydrophobically modified polyacrylamide; HAS E is a hydrophobically modified alkali swelling emulsion; H MHEC is a hydrophobically modified hydroxyl Ethyl cellulose.
