Product Description

DESCRIPTION
XC-208 is a type of aziridine modified isocyanate crosslinker, it is different with the normal blocked isocyanates, it is not reactive by NCO from unblocking as the normal isocyanates, in fact, it is reactive by the aziridine cycle-opening; Commercial XC-208 product is a white powder, mainly used as additive in the system of Nylon-66 for improving bonding strength of various adhesives; it also can be used in various fields when strong bonding effect is required in the basic system of acrylic and polyurethane water-borne resins.

APPLICATIONAS
It is mainly used in the system of Nylon-66, are also expected to possess excellent chemical resistance and high modulus;
In the system water based printed paste, can improve the abrasion resistance and gloss finish, not formaldehyde appear;
In water based acrylic resin and polyurethane latex, increase cohesive strength after heat treatment;
In any water based latex containing –COOH, -OH, -NH2, improves the resin strength and abrasion resistance, after dry and heat treatment;
In water based cotton & terylene latex, increases water and oil resistance;
In vinyl coatings to reduce plasticizer migration and improve stain resistance;
In water based concrete sealers to improve abrasion resistance
Generally, in any water based resins, improve the water, detergent, solvent, chemical resistance and abrasion resistance, after heat treatment formulation.
