Application:
Reproduction of cement and plaster products with intricate details, especially used in pouring, brushing and pieces mold
INTRODUCTION:
Our RTV silicone rubber for mold making, is normally of milkwhite color and in a viscous liquid state. It is composed of 2 parts(A: Silicone rubber, B: Curing agent), which are mixed in a proper ratio and react to turn solid during some curing time. It embraces 2 categories, namely condensation cured type and addition cured type. In order to cater to different applications and customers, we have various items with different hardness depending on customers' requirements.
Our products are applicable to multipule fields and purposes, including candle casting, resin casting, polyurethane casting, gypsum product reproduction, lifecasting, metal casting, concrete casting, etc.
As some customers may need to make colored molds, we also have our own pigments to match with the silcone rubber. If need be, it will be our pleasure to sell you colored silicone rubber, or you may do the dying process by yourselves. Just choose the best way for you.
Below is a general use guidance for our RTV silicone rubber:
TECHNICAL GUIDELINES:
1. Stir the liquid silicone (Part A and part B) well before use (except when depending on machine ).
2. Weigh the desired amount of part A into a clean mixing container, and then weigh the proper amount of part B into the container. Mix the two component together by stirring with a stick. Scrape the container walls and bottom well to insure a thorough mix.
3. Though it is often unnecessary to deair the material due to its low viscosity and our special formulation, it is better to do so to obtain a bubble free rubber. 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 container. Interruption (bumping) of the vacuum may be necessary to prevent overflowing the container. Keep the mixture under full vacuum for 2-3 minutes.
4. Bleed air slowly into the vacuum chamber. When the chamber is at atmospheric equilibrium, remove the cover plate and take out the container.
5. 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 entrapment of air bubbles under the flowing material. A "ready" 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.
6. Allow the rubber to cure for 2-4 hours at 24C before removing the cured rubber mold from the pattern. Heat acceleration is recommended if necessary.
FIRST AID:
Inhalation: Remove source(s) of contamination and move victim to fresh air. Contact physician immediately.
Eye Contact: Flush eyes with plenty of water. If irritation persists, seek medical attention.
Skin Contact: In case of skin contact, wash thoroughly with soap and water; Remove contaminated clothing and launder before reuse; Seek medical attention if rash develops.
Ingestion: Do not induce vomiting unless instructed by a physician. Contact physician immediately.
After first aid, get appropriate in-plant, paramedic, or community medical support.
