Product details

Technical Data

Description

Silicone ASSYST for PU is a silicone elastomer that hardens at room temperature by a polycondensation reaction after the addition of hardener for silicone for PU, resulting in a flexible and elastic material.

Examples of applications

This silicone is specially designed for the production of moulds for casting polyurethane resins, for serial production. The use of the products can also be suggested for moulds in which other replicating materials are cast (such as wax, plaster, etc.).

Benefits

Very high resistance to polyurethane resins, even those with a strong exothermic reaction
Easy to process due to good flow behaviour.
High mechanical resistance.
Excellent reproduction fidelity of every detail.
Easy to remove thanks to the intrinsic self-dissolving properties of silicone elastomers.
