● High purity

● Easily melt

Application

PU coatings, architectural coatings, sports materials, epoxy insulation material, waterproof wall and waterproof 

roofing materials.  Printing rollers, rollers, trolley wheels and molds of PU elastomers. 

Introduction

MOCA is used as PU (Polyurethane Resin) curing agent. The chlorine atoms on benzene ring can slow down the activity of "NH2" group, so as to extend the pot life while casting.

1. What is the Urethane Elastomer?

    (1) Definition :

    Polyurethane elastomer is flexible, and posse's elasticity nature likes rubber. The following is molecular

    structure.

    ~NCO+~OHΔ~~NH-C-O-O

    (2) Polyurethane characteristics :

    It is good for :

 

          1. Abrasion resistance

          2. Elasticity no matter with high or low hardness

          3. Tensile strength, tear strength, compression strength

          4. Chemical, oil ozone and cold resistance

          5. Impact resistance

          6. Absorption of vibration

          7. Workability and so on 

 

    This is Cross linking and good curing agent for PU elasticity. The finished products as following:

 

          1. Caster: PU Caster and Wheels

          2. Seals: PU Hydraulic Seals and Packages

          3. Spring: PU Rod , Sheet , Bar and Film

          4. Blade: PU Drum Blade for Copier and Laser Printer

          5. Roller: All Kinds of PU Rollers

          6. Parts: PU Flexible Coupling and Parts

 

    Also we can recommend and introduce the supply of prepolymer and finished products for your asking
    only.
