PACTOTop Seal PS is a two-part high performance polysulphide civil engineering and construction sealant. It has a low modulus and is a chemically curing polysulphide joint sealant developed for dynamic joints. The product has been formulated to seal and reseal high movement joints in building and civil engineering structures and for the sealing of joints subjected to rapid movement.
This sealant cures to form an elastomeric rubber like seal, through a chemical reaction and is capable of accommodating cyclic movement during the curing process. It has the ability to withstand repeated cycles of compression and extension over a wide temperature range.
PACTOTop Seal PS will bond to most building substrates including concrete, brick, stone, wood and mill finished aluminum. Primers are available for most types of substrate.
The sealant possesses excellent application and tooling characteristics which results in achieving a high standard of finish.
PACTOTop Seal PS is available in both gun and pouring grade, for horizontal, vertical and overhead applications.
