China Jinwei Anion Polyacrylamide Auxiliary in Car Paint Industry

Polyurethane auxiliary curing agent is a one-component polyurethane, Hydrophobic or Hydrophilic resin, which reacts with water to produce a flexible or inflexible grout suitable for waterproofing and sealing cracks and joints of concrete surfaces, and for effectively stopping water leaks.
Hydrophilic Polyurethane foaming agent is used in ground improvement. once contact with water, it expands quickly to block its cracks and stop water leaks. It can also be used in conjunction with the low amount of catalyst and form an colloid to stop water and fill the cracks.
Auxiliary curing agent featuresIt has low sticky degree, so it doesn't lead to blocking due to the improvement of sticky degree inside coating pipe. Also, it is easy to construct & has good operation.It has good water-soluble performance, so do not result in the residual water exited in cracks which will destroy the foaming for a long time, finally leading to secondary water leakage.It finishes the solidification when going through water after 20-120 seconds.It has good stability and will not go bad during the construction after opening the seal. Also, it can keep in reserve, without deteriorating, for half a year before breaking the sea.It is well sticky with concrete and has good colloidality, no delaminating with concrete.It doesn't affect the physical property of the foaming when going through mete-acid, sea water and so on.It has a long-time water resistance, strong structure & high toughness.
