MIXING INSTRUCTIONS:
1. Weigh out the required amount of RTVS 16.
2. Measure the required amount of catalyst. See RTVS Catalyst Selector Guide.
3. Mix thoroughly, scraping both the bottom and sides of the mixing container.
4. Evacuate mixture @29 in Hg. for 3-4 minutes to insure a void-free casting.
5. Pour into unit or cavity.
CURE SCHEDULES:
Overnight at room temperature (24 hours at 25°C.) Faster tack-free surfaces achieved using varied catalysts.

HANDLING PRECAUTIONS:
RTV silicone rubber base compounds and the curing agents for addition cure products are non-hazardous and practically non-toxic. Curing agents for condensation cure products contain tin soaps which can irritate eyes and skin of some individuals. Avoid contact with skin; if contact occurs, wash affected areas at once with soap and water. Avoid contact with eyes. In case of contact with eyes, flush with water for 15 minutes; call a physician.
PLEASE REFER TO MATERIAL SAFETY DATA SHEET FOR FURTHER FIRST AID INFORMATION.
