TM-197
|
Features and main uses：
|
|
TM-197 polyester resin is a kind of bisphenol-A unsaturated polyester resin. It has good chemical resistance, especially alkali resistance, which is significantly better than other polyester resins. Its pouring body has high thermal deformation temperature, which is suitable for manufacturing FRP pipes, containers, tanks and other chemical equipment.

Matters needing attention:
|
|
1. When the construction environment temperature is high and the gel time is short, the dosage of curing agent can not be reduced, and the inhibitor should be added as needed. When the surface is sticky, proper wax solution should be added.
|
|
2. The product should be stored in a cool place below 25 ℃ to avoid fire and keep away from heat and radiation sources. The shelf life of products stored below 25 ℃ is 3 months.
