RTV2 poly addition silicone rubber bag for shaping
System for the production of reusable silicone vacuum bags.
ZA 22 WT 20 Thixo Spray can be applied by spraying (with a spray machine) or by brush. It has very good mechanical properties and excellent chemical compatibility with polyester resins and vinyl-ester resins. Good compatibility also with epoxy resins.
IMPORTANT! To avoid two layers of silicone separating, the second layer must be applied within 4 h (@23C) of the first. If the second layer of silicone is applied more than 4 h later, the two layers may not adhere perfectly, leading to problems during use.
Higher temperatures reduce this time; lower temperatures extend it.
To extend the life of the mould, we recommend removing the composite product as soon as the resin polymerises inside the vacuum bag.
