supplytackifier

Viscosifier means used as viscosity additive. Under the characteristic temperature and humidity conditions, the tackifier can extend the time that the adhesive remains dry after coating the bottom substance. Viscosifiers are often used to improve adhesion between substances in contact with each other. Two surfaces in contact with each other, commonly referred to as adhesives and substrates, are in contact with each other under weak pressure, and the tackifier can cause a certain strength of the connection between them. As a adhesive, tackifier is mainly used to improve the initial adhesion of the product. Used in the paint mainly to improve the adhesion with the substrate increase! two Viscosifier principle: The viscosifier is added to the modified asphalt and wets the adhesive surface through surface diffusion or internal diffusion, so that the bonding strength between the modified asphalt and the bonded material is improved. According to the different solubility in the two phases of ABA block copolymer thermoplastic elastomers, the commonly used viscosifiers are divided into three categories. A class of solubility parameters are generally relatively low, can only be compatible with non-polar rubber phase, petroleum asphalt, aliphatic and alicyclic petroleum resins, rosin and hydrogenated rosin resins, terpene resins belong to this class, they can reduce the elasticity and modulus of self-adhesive modified asphalt and cohesion strength, and give self-adhesive modified asphalt with initial adhesion and stripping strength. Three. Viscosifier classification: viscosifier is divided into water-based oily, water-based viscosifier emulsion, water-based viscosifier resin, water-based viscosifier powder; Oil-based enhanced rosin resin, modified rosin resin.
