Model:polysulfide joint sealant
Polysulfide sealant
Description
Double component polysulfide sealant is a two-component waterproof material which is singly packed and solidifies under ambient temperature. It is also called sealing paste because it is a paste. The polysulfide sealing paste is based on liquid polysulfide rubber, with addictive of various chemical assistants and polymer material, processed with special synthesis procedures. It is a perfect poison-free waterproof sealing material
Advantage:
1. Two component polysulphide sealant
2. High resilient with excellent recovery characteristics
3. Permanent and uniform watertight seal
4sed for flexible joints in Subway, highway pavement, Airport Runway, reservoirs
5. Excellent resistance to fatigue and stays flexible throughout its service life-won’t become brittle, caulk or crack due to ultra violet exposure
6. Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes
7. Excellent adhesion to most common building substrates
8. Good resistance to ageing. Retains joint soundness once cured
9. Resistance against mild chemicals, hydrocarbon fuels, sea water
10. Non-toxic, can be used in potable water applications, swimming pools and tank
