True Skin 20 - Professional Platinum Silicone Elastomer

This is a castable, two-component, addition-curing silicone elastomer system. After mixing parts A and B in the correct proportions, the system will cure at ambient temperature within 24 hours, but the cure rate can be accelerated by applying heat. The cured rubber exhibits excellent physical and electrical properties.

Use and Curing

IMPORTANT: The "A" part of the product contains the platinum catalyst; great care must be taken when using automatic dispensing equipment. Ensure it is not contaminated by residual hydride-containing rubber in the dispensing equipment, as curing will occur.

Mix

Both 'A' and 'B' parts must be thoroughly stirred to ensure a uniform mixture. Place the required amount of 'A' and 'B' parts by weight in a 1:1 mixing ratio in a clean plastic or metal container approximately three times their volume and mix until the mixture is uniform in color. For best results, we recommend degassing intermittently at 30-50 mbar for 5-10 minutes.

Curing conditions

Mixing the components at temperatures between 15 and 25°C is recommended to ensure sufficient pot life for degassing and handling. Pot life can be extended to several hours by cooling the components before mixing.

Inhibition of Hardening

Great care must be taken when handling and mixing. Curing can be inhibited by the presence of nitrogen, sulfur, phosphorus, and arsenic compounds; organotin catalysts and PVC stabilizers; epoxy resin catalysts; and even contact with materials containing some of these substances, such as modeling clay, sulfur-cured rubbers, condensation-curing silicone rubbers, onions, and garlic.
