Composition and properties of polymer waterproof sealant:
Polysulfide sealant waterproof system of liquid polysulfide rubber as the main material, with tackifying resin, curing agent, accelerator, reinforcing agent made of strong sealant. This sealant has excellent resistance to oil, hydraulic oil, water and atmospheric aging resistance of various chemical properties and the heat and is generally can be vulcanized. According to the group can be divided into two components (or three components) and one component type. The machining process with premixed - grinding - filling.
A detailed description of high modulus two-component poly sulphur seal:
Construction temperature is over 5 DEG C, otherwise it will affect the adhesion and curing speed. High modulus two-component polysulfide sealant. Self leveling two-component polysulfide sealant. In the long-term use will not cause yuan loss. During the expansion of two-component polysulfide sealant is a kind of waterproof performance is very stable, is the molecular end with -SH based, -SS- bond in the molecular chain of liquid polysulfide rubber as the main agent, sealing material with metal peroxide as two-component curing agent, two component mixed with a given proportion, often forming temperature curing rubber like elastic body.
