GEL ISOLANTE SOFT SIL GEL 32

GEL ISOLANTE SOFT SIL GEL 32 (500 gr)

Fast cure silicone gel

Introduction
SOFT SIL GEL32 is a soft, adherent, clear general purpose silicone elastomeric gel designed for use electronic and electrical application for encapsulation and Potting.
It is a low viscosity, 2-component system that is readily mixed in a 1:1 ratio.
It is used also to enhance the performance of textiles, providing a moisture resistant, soft, flexible layer to fabric applications and is specially recommended for use in adjusting the modulus properties of mattresses.

Key Features
General purpose silicone gel
Simple 1 to 1 mix ratio
Fast cure at room temperature
Use and Cure Information
How to Use
SOFT SIL GEL32 is supplied in several pack sizes and consists of kits containing equal quantities of Parts ‘A’ and ‘B’.
Containers should always be kept sealed when not in use, and all mixing equipment must be clean and free from contaminants such as organo-tin, -sulphur, -nitrogen compounds which can poison the catalyst and prevent proper cure.
Application and Cure
Each of the SOFT SIL GEL32 component parts should be mixed in the recommended one-to-one ratio (by volume or weight).
Automated mixing and dispensing is recommended for this product due to the very short pot life.
Please our sales Manager to discuss machine dispensing options.
The curing process begins as soon as the components are mixed and the working or pot life of the mixed system is dependent on the ambient temperature conditions.

Note: Chilling the separate component parts, before and after mixing, will extend the pot life, but not
indefinitely.

Data sheet

Adhesion
Fully cured SOFT SIL GEL32 exhibits good adhesion to most substrates such as:
Aluminium, stainless steel, ABS, polycarbonate, PCB boards, Nylon 6,6
Inhibition of Cure
Great care must be taken when handling and mixing all addition cured silicone elastomer systems, that all the mixing tools (vessels and spatulas) are clean and constructed in materials which do not interfere with the curing mechanism. The cure of the rubber can be inhibited by the presence of compounds of nitrogen, sulphur, phosphorus and arsenic; organotin catalysts and PVC stabilizers; epoxy resin catalysts and even contact with materials containing certain of these substances e.g. moulding clays, sulphur vulcanized rubbers, condensation cure silicone rubbers, onion and garlic.
