A two-component polysulfide sealant (glue) is a liquid rubber as main material, the production process for synthesis of polymer materials and adding a variety of special chemical additives, is a novel waterproof sealing material non-toxic, excellent water resistance, oil resistance, aging resistance, corrosion resistance and sealing. Good, strong adhesion, good elasticity, long service life is known.

Polysulfide sealant (glue) technical index standards: JC/T483 - 2006 performance name of type A and type B grade a nonconforming product qualified fine first density, g/cm3 1。50 + 0。1 for the period, H 2 ~ 6 dry time table, H = 24, exudative rheology index less than or equal to 4 Sag (type N), mm more than 3 leveling (L type), mm smooth C -30 -40 -30 low temperature flexibility, tensile bond of maximum tensile strength, MPa = 1。2 = 0。8 = 0。2 = 100 = maximum elongation,%400300200加热失重,%10610

A detailed description of high modulus two-component sealant:

High modulus two-component polysulfide sealant before construction to remove oil, sticky surface attachment, dust and other debris, ensure the adherend surface dry, smooth, to prevent bad adhesion。 The high modulus of two-component polysulfide sealant。 Polysulfide sealant。 Safe, non-toxic two-component polysulfide。 Sealing glue is a kind of waterproof performance is very stable, is a molecular terminal 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 as an elastomer。Water sealing materials are widely used in civil engineering。 1, with weather resistance, good durability, long-term use of cracks
