1.non-toxic,no pollution, 2.anti-mildew, anticorrosion 3.waterproof, good resistance to oil,acid,alkali
Polysulfide sealant manufacturers,we are a big factory in Beijing!
The sealant is double-components cream,component A is white polysulfide sealant, component B is black curing
agent, mix ratio 12:1 to 10:1. The polysulfide sealant used for waterproof joint sealing or caulking in
subway,tunnel,driveway,highway,bridge, natatorium, cistern, hydro powerstation, sewage treatment, water supply
and drainage system.
The sealant is a netural substance, main characters:
1.non-toxic,no pollution,2.anti-mildew, anticorrosion3.waterproof, good resistance to oil,acid,alkali4.Tack free time less 24 hours, waterproof test can be carried out at 7 days, maxium adhesion will get in 28
days.
Instructions:
1.Clean working surface, make it dry, no dirt no oil.2.Mix component A and B by ratio 12:1 to 10:1(in lower temperature use more component B, high temperature use
less component B), fully mix two components until mixer’s color looks pure, well-distributed.3.Inject the mixer into joint by sealant gun, use trowel make surface plain.4.Use any waterproof cloth(fabric) keep the joint surface from rain or water in 24 hours.
