5.How to use Rtv-2 silicone rubber For Cornice molding ?
1. Stir the base (Part A) well beofre use (except when depending on machine ).
2. Shake the catalyst container (Part B) well before use.
3. This is a 100 Part A to 4 Part B mixing ratio by weight.Weigh the desire amount of base into a clean mixing container.
4. Weight the proper amount of catalyst into the container. Mix the base and catalyst together by stirring with a stick until a uniform color is obtained. Scrape the container walls and bottom well to insure a thorough mix.
5.Though it is often unnecessary to deair the material due to its low viscosity some may choose to do so. If so,place the container into a vacuum chamber and evacuate the entrapped air from the mixture using a vacuum pump capable of achieving 29 inches of mercury vacuum.The mixture will rise, crest and then collapse in the contanier. Interruption(bumping) of the vacuum may be necessary to prevent overflowing the container. Keep the mixture under full vacuum for 2-3 minutes.
6. Bleed air slowly into the vacuum chamber. When the chamber is at atmospheric equiplibrium,remove the cover plate and take out the container.
7.Pour the deaired material slowly in a steady stream from one end of the mould so that the material flows evenly over the pattern. This should minimize emtrapment of air bubbles under the flowing material. A mold may be poured firstly over the pattern, which will also help reduce the possibility of entrapping air on the pattern and in the cured rubber.A mold release agent may be applied on the pattern first to improve release.
