Two component polysulfide sealant liquid polysulfide rubber as the basic material, polysulfide sealant is a kind of two-component sealant which can vulcanize and crosslink automatically at room temperature. It can perfectly bond metal and concrete.
Liquid polysulfide rubber as the basic material, polysulfide sealant is a kind of two-component sealant which can vulcanize and crosslink automatically at room temperature. It can perfectly bond metal and concrete, can maintain good performance for air tightness and waterproof in continuous expansion, vibration and changing temperature, additionally, pretty good functions of oil resistance, solvent resistance, durability.
1. Excellent construction performance, water resistance, oil resistance and chemical resistance; 2. Wide range of application, superior adhesion with the majority of metal and nonmetal building materials. 3. Curing in room temperature, curing speed can be controlled, non-corrode the building material. 4. Low modulus, high extension and elasticity, can withstand the continuous and obvious cycle displacement. It can be used in conditions of continuous expansion, vibration and changing temperature for a long time.

Scope of Application
Waterproof seal for metal, concrete wall joint, underground engineering (such as tunnel, culvert), reservoir, etc. Expansion seal for highway pavement, runway's expansion joint, building crack's repair and recovery seal.
1. Carefully clean the bonding surface by steel brush or fur brush, make sure no dust, no attachments, and erase oil pollution by acetone, guarantee the bonding surface dry and clean. 2. Tamping plate joint by polystyrene material which is slightly wider than the joint, adjusting the depth of the plate joint nearly to 50% of the seam width. 3. According to the instructions formulating the two-component sealant, mixing uniformity, according to the actual amount formulating, so as not to waste. 4. Place the evenly mixed sealant into the cylinder, press into cracks by squeeze gun, then compact it with scraper to make even and neat.
Polysulfide sealant is non-flammable, no explosion danger products, can transport as general non-dangerous goods. Take strict precautions against sunlight and rain, ban close to heat source, preventing hit and extrusion, keep the packing is in good condition in transportation. Stored in cool, dry and ventilated warehouse. In no more than 27℃conditions, since the date of production, storage period for six months.
A small package contained 6 barrel in carton, A and B tie in, total weight 25 KG.
A big drum package, net weight 200KG of A component, net weight 20KG of B component,tie in.
