PZBI-25 fixing agent Menadiona Mina original imported genuine factory direct sales

PZBI-25 is a fixing agent and cross-linking agent that can improve cohesion and binding force, which will make the coating have better physical and chemical properties, especially better scratch resistance, water resistance, chemical resistance . This is a blocked isocyanate. The aziridine at both ends will react with active hydrogen, such as carboxyl groups in acrylic emulsions and polyurethane dispersions. It is worth mentioning that no CO2 was released during the reaction and no formaldehyde was released.

Use of PZBI-25 fixing agent:

Under certain conditions, PZBI-25 can react with a variety of functional groups, such as carboxyl, hydroxyl, chlorosulfonic acid, amine compounds, and even ester compounds. Such reaction conditions can range from reaction with carboxyl groups at room temperature to reaction with hydroxyl groups at 150 ° C. Most reaction conditions are 80 ° C-120 ° C, which can accelerate and complete the crosslinking process. The amount of addition depends on different applications and processes, but in general, 1% -3% of the total weight is a good recommendation.
