Product Description

Product Description

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.

Advantages	Disadvantages
Better water resistance. Better physical properties, recovery adhesion, peel adhesion, and tensile adhesion. Best air tightness among all the sealants. Can maintain flexibility over a wide temperature range. Can resistant water, oils, grease, most solvents, mild acids and alkalis. Cost lower than one component sealant.	Requires mixing, but easily to mix. Light colors be a problem. Limited filling life, and very short filling life at 100 °F. Slight odor. Poorer UV resistance compared with urethane and silicones. Need primers for porous substrates.

Application

The polysulfide sealant is suitable for outdoor or indoor and can be used to seal both static and dynamic joints:

• Used to caulk at concrete, building, and bridge.
• Used in anti-leakage caulking of various types of expansion joints, such as waterworks, swimming pools, reservoirs, power plants, dams, sewage treatment works and water supply and drainage systems and other projects.
• Used as the joints of precast concrete, and the seams of the glass and construction.
• Used in the seaming of metal siding, and the bonding of aluminum window frame.
