QuickSeal Tapes
QuickSeal tapes from Seal Trust™ are pressure sensitive adhesive tapes, which remain flexible even in cold temperatures. QuickSeal tapes may be used on metal roofs to strip in side laps, end laps, and other penetrations prior to the application of a coating system (with the use of QuickSeal Fabric Tape). QuickSeal tapes may also be used on EPDM, TPO, CSPE/Hypalon, CPE, SBS, APP modified, asphalt BURs, all metal roofs, tiles, aluminum, galvanized steel, gypsum board, wood, polyethylene, propylene, polystyrene, fiberglass, brick, concrete, masonry and OSB. This product may be used to repair gutters, chimney flashings, and metal roofs on mobile homes and transport vehicles. QuickSeal tapes make a watertight seal. Can be installed in temperatures down to 20°F (with EPDM Tape Primer). Available in black, white, and fabric. The fabric facer is designed to be coated to match the surrounding roofing surface. The white TPO facer makes QuickSeal tapes UV resistant.
Storage: Store in warehouse without excessive heat. Do NOT store long term on roof.
Shelf Life: 5 years if stored between 60° and 80° F.

Latex Bonding Adhesive Product Information:
Seal Trust™ Latex Bonding Adhesive is a white water based adhesive used in adhering EPDM or TPO membranes to various substrates. Product goes on white and dries by evaporation to a clear film.
Application Instructions:
Each gallon covers approximately 100 square feet ONLY. Apply enough adhesive to roof substrate so that membrane will be coated by adhesive when rolled into it. MEMBRANE MUST BE LAID INTO WET ADHESIVE. Wrinkles may be brushed out while adhesive is still wet. ON HOT DAYS, THE ADHESIVE MAY DRY TOO FAST TO USE THIS PROCEDURE. If so apply a thin coat of adhesive to the roof surface and the back of the membrane. For highest initial bond strength join after film becomes tacky. Initial tests indicate that adhesives may be used at temperatures as low as 40F. DO NOT ALLOW MATERIAL TO FREEZE. Meets OTC VOC requirements.

Product Information:
Seal Trust™ TPO Neoprene Bonding Adhesive is designed for use with TPO membranes to adhere to insulation boards such as ISO and wood fiber and also to wood, metal, masonry and approved roofing substrates. It may also be used as a general contact bond adhesive for both vertical and horizontal surfaces. May be applied using brush, roller or squeegee and also may be sprayed applied using proper equipment.
Application Instructions:
Recommended application instructions for use in TPO projects are printed on the container label. Care must be taken to ensure adequate adhesive coverage when using some substrates with irregular surface patterns. Stir well before use. May be warmed to room temperature before use to promote easier application. Apply a thin coat to both intended surfaces and let adhesive “dry” until it is tacky to the touch. Mate both surfaces and apply mild pressure. Once the intended surfaces are mated, it will not be possible to reposition them without breaking the bond. Membrane should be rolled when completed. CAUTION. Keep bonding adhesive out of the seam areas at all times!
