Construction method of poly sulphur waterproof sealant:

1, sealed surface treatment: before construction to remove oil viscosity on the surface of the attachment of dust and other debris, ensure the adherend surface drying, smooth to prevent bad adhesion。 2, filling the back lining material: according to the design requirements, to the joint is filled in the backing material。

3,Sealant preparation: according to mix instructions given, two component mixed evenly, can be used, regardless of mixer or hand mixed, should reach uniform color no color. Mixing should prevent bubble mixing, coating should prevent bubble mixing, compaction, fill seal waterproof two-component polysulfide. Room temperature vulcanized sealant is liquid polysulfide rubber based prepared two-component sealant, it can be in continuous expansion, vibration and temperature change to maintain good durability, air tightness and water resistance. The product is equipped with a coat paint has good adhesion to metal, concrete material, convenient construction and operation simple, is the building construction, waterproof and permeability of the indispensable sealing material.

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.
