Safety & Health
- Deareation and Precaution
Any air trapped during the mixing cycle should be removed in order to avoid bubbling in the silicone rubber mold. This involves placing the container in a suitable vacuum chamber and apply a vaccum, which causes the mixture to froth to around four times its original volume. With a 20 mm. vacuum, deareation is completed approximately 2 minutes after the frothing ceases.
Curing may be inhibited if substrate contains water, sulfur, nitrogen compounds, organometallic salts, phosphorous compounds, etc. – a preliminary test is therefore recommended.
