Trelleborg C-56 is custom engineered to meet the most exacting standards of the precast concrete industry. It remains flexible and forms a permanent bond to a wide variety of substrates including concrete, metals and plastics.
Adhesion and cohesion at the time of installation are excellent and improve after the joint has been formed and placed into service.
This sealant is designed not to shrink, oxidize or harden and has excellent resistance to temperature extremes, acid and alkaline environments. It is also designed to fully comply with current ASTM standards and specifications as required by federal, state, and local agencies for use by the precast concrete industry and contractors.
Joint surfaces should be clean and dry. Due to the high adhesive quality of Trelleborg C-56, priming of the joint surface is usually not required. In case of wet or unusually demanding applications, it is recommended that an adhesive primer be applied to the joint surface and allowed to dry before application of the sealant.
The size (cross-section) of Trelleborg C-56, required for a specific joint is determined by the annular space resulting in a fully sealed joint. The joint must be coupled with sufficient compression to form a proper watertight seal.
