Aziridine crosslinking agent PZBI-25, imported from Menadiona, Spain, with factory price direct sales
Overview of PZBI-25 fixing agent: PZBI-25 is a fixing agent and crosslinking agent that can improve cohesion and adhesion, which will give coatings better physical and chemical properties, especially better scratch resistance, water resistance, and chemical resistance. This is a blocked isocyanate. The aziridine at both ends will react with active hydrogen, such as the carboxyl group in acrylic lotion and polyurethane dispersion. It is worth mentioning that no CO2 or formaldehyde is released during the reaction process.

Menadiona 25 fixing agent PZBI-25 aziridine crosslinking agent application in Spain:
Under certain conditions, PZBI-25 fixing agent can react with various functional groups, such as carboxyl, hydroxyl, chlorosulfonic acid, amine compounds, and even ester compounds. The range of this reaction condition can range from reacting with carboxyl groups at room temperature to reacting with hydroxyl groups at 150 ℃, with most reaction conditions being between 80 ℃ and 120 ℃, which can accelerate and complete the crosslinking process. The amount of addition depends on different applications and processes, but generally speaking, 1% -3% of the total weight is a good recommendation.
Azoproridine cross-linking agent PZBI-25 is used in coating, printing ink, textile, printing and dyeing and other industrial fields. In acrylic lotion, it can improve adhesion and water washing resistance, and can be used as a fixing agent with an addition amount of 1% -2%; In printing and dyeing leather coating, to improve washing resistance, enhance color fastness, and make the hand feel softer, the addition amount is 1% -2%
