Polyurethane mould glue 90AB 30min gel time
Description
This system materials is Bi-component. A is polyol component, and B is MDI-terminated pre-polymers.
Application
This system material is used to produce various Pu mould, such as shoe mould, concrete mould tec. It can substitute silicone rubber to produce “artificial culture stone”.
Characteristic
It has excellent processing properties, cured under room temperature, short demould time, and the color can be changed by adding pigment. The final products are transparent which enjoy good abrasion resistance, water resistance, good resilience.
