TremPro JS-773 is formulated for ground waterproofing of frame joint surfaces and can also be used in-plant

TremPro JS-773 is used as an exterior or interior joint sealant, illmod 600 can be used as a primary or secondary seal in vertical joints. It is suitable for vertical expansion joints, joints in pre-cast concrete, masonry, and facades, roofing and insulated metal panels, exterior insulation finish systems (EIFS), and primary seal in starter track assemblies for window wall.

TremPro JS-773 is also useful for greasing or bedding non-porous constituents that have been fastened around each other, as well as for ground caulking the internal segment spliffs of PEMB panels. TremPro JS-773 is simple to apply with standard silicone sealant. Conventional compressors can be used with containers and drums. Tremco advises a compressor with the least ratio of 20:1. It can be utilized to avoid conductivity intervention by separating dissimilar materials. The product adheres well to metallic materials and metal completes such as hot-dip galvanized steel, Galvalume, Kynar 500, coated steel, polyvinylidene fluoride (PVDF), aluminum, and fiberglass.
