Liquid polysulfide rubber as the basic material, adding tackifying resin, vulcanizing agent, accelerant and fortifier makes up the two-component polysulfide sealant (double-component polysulfide sealant). It is a kind of two-component sealant that can vulcanize and crosslink by itself at room temperature. Its appearance is exquisite and even paste or ropy liquid, so it is also called two-component polysulfide sealing paste. It is made up of A component and B component. A component is hoary even paste and B component is black even paste. The two components have clear color difference, which makes the mixing more convenient. The mixing ratio is A : B=100 : 8 - 12. It has good bonding effect to metal, concrete and other material. It can keep good air tightness and waterproof ability in continuous vibration and temperature changes.
The classification of two-component polysulfide sealant:
It can be divided into two kinds according to the flowability: non-slumping and self-leveling.
It can be divided into two kinds according to the movement ability: 25 and 20.
It can be divided into two kinds according to the tensile modulus: high modulus (HM) and low modulus (LM).
Features:
Excellent adhesion performance: it has good bonding effect to cement, steel, glass, wood and natural stone.
Resistant to water: it is stable facing sea water, tap water and distilled water.
It is not resistant to concentrated acid and alkali. But it is stable facing the diluent inorganic acid, alkali and various salts.
Excellent anti-aging and resistance to high temperature. It can work in the temperature of -40°C - +120°C for long time.
Resistant to ultraviolet.
Non-toxic, good air tightness and high elasticity. It has the best air tightness among all the sealants.
