Difference between china POLYURETHANE SEALANT FOR GENERAL USE and polysulfide sealant

(Summary description)China POLYURETHANE SEALANT FOR GENERAL USE universal two-component polyurethane sealant is a two-component polyurethane sealant with polyethylene adipate as raw material, solvent polyurethane resin as main component (component a) and trimethylolpropane-t1) I adduct as curing agent (component B).China POLYURETHANE SEALANT FOR GENERAL USE is also known as 101 polyurethane sealant. Universal two-component polyurethane sealant is mainly used for the bonding of insulating materials, packaging materials, composite films, porous materials, cryogenic protective materials, etc.

Information

Polysulfide sealant is a sealant synthesized with liquid polysulfide polysulfide rubber as the main body and combined with vulcanizing agent, accelerator, reinforcing agent and other additives. Polysulfide sealant is also divided into single and two components, with little difference in performance. It has excellent properties such as oil resistance and weather resistance, and has good bonding effect with most materials. It is widely used in the sealing of metal and glass, and the concrete caulking of water pools, dams, bridges and tunnels.

China POLYURETHANE SEALANT FOR GENERAL USE universal two-component polyurethane sealant is a two-component polyurethane sealant with polyethylene adipate as raw material, solvent polyurethane resin as main component (component a) and trimethylolpropane-t1) I adduct as curing agent (component B).China POLYURETHANE SEALANT FOR GENERAL USE is also known as 101 polyurethane sealant. Universal two-component polyurethane sealant is mainly used for the bonding of insulating materials, packaging materials, composite films, porous materials, cryogenic protective materials, etc.

1、 The tensile property and toughness of china POLYURETHANE SEALANT FOR GENERAL USE are stronger than polysulfide sealant. The elongation at break of polyurethane sealant can reach about 900%, while polysulfide sealant can only reach 400%. Therefore, polyurethane sealant should have better construction effect in the caulking of expansion joint and deformation joint.

2、 Polysulfide sealant has a wider application range than china  POLYURETHANE SEALANT FOR GENERAL USE, and its application is more extensive. Its adhesion on some special materials such as glass and plastic is better than china POLYURETHANE SEALANT FOR GENERAL USE, but polysulfide sealant cannot be mixed with silicone sealant, which will greatly reduce the adhesion of polysulfide sealant.

3、 Polysulfide sealant will release sulfide gas before and after curing. The gas not only contains peculiar smell and pollutes the environment, but also endangers human health if inhaled for a long time. Finally, the surface drying and complete curing time of china POLYURETHANE SEALANT FOR GENERAL USE is shorter than that of polysulfide sealant, which is a better choice for construction projects in a hurry.
