Mould Making Polyurethane Resin Transparent Liquid

                     Two Component Polyurethane Resin for Mould Making

1. Description

Pu rubber is two-part compounds that vulcanizes at room temperature.With 100% polyurethane resin properties. Containing no contain solvent,after curing, it will be forming a is light yellow clear also glittering layer.it's used extensively in industry, voltage transformer potting. A/B after curing ,it has excellent weatherability and resistance to UV - irradiation.Environmentally product,when in the sunshine,it can't change the color within short time.

2.Characteristics

PArt A is multi isocyanate compound,part B is polybasic alcohol compound,we can adjust

the hardness,working time ,curing time and viscosity with your references,meet the different needs whatever produced by machine or manul

Composition:

Part A 1. isocyanate R-N=C=O 2.polybasic alcohol R-[O-CH2-CH]nOH

part B 1.polybasic alcohol R-[O-CH2-CH]nOH 2: Isocyanate R-N=C=O

3.Catalytic agent C8H8HgO2;CH3COOC6H5Hg

4. Properties
