Two Component Polysulfide Sealant
Two-component polysulfide sealant, as known as a two-component, non-sag, premium polysulfide sealant, which is also called polysulfide sealant for building made up of liquid polysulfide rubber, and add tackifying resin, vulcanizing agent, accelerant and fortifier into it. It contains two components and it can vulcanize and crosslink by itself at room temperature. The two components have clear color difference, which makes the mixing more convenient. It can keep good air tightness and water resistance in continuous vibration and temperature changes. In addition, it has a good bonding effect for metal, concrete and other materials.
The polysulfide sealant is suitable for outdoor or indoor and can be used to seal both static and dynamic joints:
