TREMPRO® JS-773+ Butyl Elastomer Sealant

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

Basic Uses: TREMPRO® JS-773+ is designed for in-plant caulking of panel joints. It is also ideal for buttering or bedding non-porous components that are squeezed together by fastening or for caulking the interior panel joints of PEMB panels. Additionally, it can be used to separate dissimilar metals to prevent galvanic action. The product exhibits excellent adhesion to various metals and metal finishes, including hot-dip galvanized steel, Galvalume®, Kynar 500®, stainless steel, polyvinylidene fluoride (PVDF), aluminum, and fiberglass.

Packaging:

• 10.1-oz cartridges
• Quart (850ml) cartridge
• 20-oz (600-mL) sausages
• 5-gal pails
• 52-gal drums

Colors: Off-White

Availability: Available immediately from your local Tremco Field Representative, Tremco Distributor, or Tremco Warehouse.

Limitations:

• Not recommended for use on exposed applications.
• For in-plant use only.

Substrate Preparation: Ensure the joint surface is sound, clean, and dry for good adhesion.

Application: TREMPRO® JS-773+ is easily applied with conventional caulking equipment. Pails and drums can be applied with standard pumps, with Tremco recommending a minimum 20:1 ratio pump. The sealant will adhere to substrate and mating surfaces in temperatures ranging from -5°F (-20°C) to 120°F (49°C). Store the product at room temperature for optimal performance. Assemble components within 24 hours after application to prevent tracking and dirt attraction that may inhibit adhesion. For recommendations on extended storage conditions, consult Tremco Technical Services at 1-866-209-2404. Extended exposure to elevated temperatures may alter the non-skinning and non-drying characteristics of the sealant. Damaged sealant can be repaired; consult Tremco Technical Services or a Sales Representative for repair procedures.

Clean Up: Tooling is recommended immediately after application to ensure firm, intimate contact with the joint interface. Dry tooling is preferred. Excess sealant and smears adjacent to the joint can be removed with mineral spirits or a similar solvent.

Warranty: A repair or replacement warranty is available for all Tremco products. Visit Tremco Warranties for details.
