Key Differences from Silicone Sealants"},"content":{"rendered":"

When deciding on sealants, you will see the terms RTV and silicone. Related but distinct, important differences between them have implications for their performance and applications.<\/p>\n

Basic Definitions<\/h2>\n

RTVA (Room Temperature Vulcanizing)<\/strong>: Sealant that cures at room temperature with heat. The word itself refers to the process of curing; not the makeup of the material.<\/p>\n

Silicone<\/strong>: A synthetic polymer composed of silicon, oxygen, carbon and hydrogen that can be found in both adhesives and sealants.<\/p>\n
