Product Data Sheet

TREMPRO® JS-773+ is a high solids, non-skinning, non-drying, synthetic, butyl elastomer sealant.

TREMPRO JS-773+ is designed for caulking of panel joints. TREMPRO JS-773+ is also ideal for buttering or bedding non-porous components that are squeezed together by fastening or for caulking of the interior panel joints of PEMB panels. It can be used to separate dissimilar metals to prevent galvanic action.

Features & Benefits

TREMPRO JS-773+ is a synthetic, high solids, butyl sealant that will not skin over or cure. It will remain permanently flexible for the lifetime of the sealant, continuing to allow for movement and compression between components. This enables components to be assembled after the sealant is applied without compromising the integrity of the seal, making it a perfect choice for factory‑assembled panel systems.

• Long open time offers flexibility during application, allowing large assemblies to be positioned before fastening
• Provides excellent air and vapor sealing
• Resists cracking or hardening over time
• Provides long-term elasticity
