Product Introduction

Spraying polyurethane polyurea elastomer is developing on the basis of ReactionInjectionMolding (RIM). In terms of processing materials, the technology has gone through three stages: (1) pure polyurethane (PU, (2) PU polyurethane (PUA), (3) PUA. In system 1 (2), in order to improve the reactivity, it is necessary to add catalyst; System 3 is completely different, it USES end amino polyether and amine chain extender as active hydrogen component (hereinafter referred to as R component), and isocyanate component (hereinafter referred to as A component) with high reactivity, without any catalyst, can be at room temperature (or even below 0C) instantaneous reaction

Anyone ever did an interesting experiment [5: in the steel, concrete, asphalt surface spraying aliphatic SPUA materials, will be 5-196 - c of liquid nitrogen coating from 30 centimeters, spray to the sample surface for 30 seconds, did not see any coating, when reduced to 10 2 cm jet distance, slight crackle coating on the surface of the steel and concrete, and asphalt surface coating is intact. The other will be coated with SPUA material of concrete samples from 1. 8 m high free fall, concrete itself was shatter, but, SPUA materials with no damage and concrete debris firmly together.
