Product Description

Saturated TGIC Polyester Resins for Engineering Machinery

NH3362 is a saturated carboxyl polyester resin for polyester/TGIC powder coating system, it is designed for low temperature curing powder coatings.

In recent years, the state has attached great importance to the construction of "revolutionary railways". The hot progress of my country's infrastructure projects and the bright future situation have also greatly stimulated the upstream raw material industry.
In terms of infrastructure projects and construction machinery, there are strict requirements for raw materials, such as weather resistance, anti-fouling, frost resistance, anti-corrosion and so on. Especially in the field of construction machinery, because most of them work in the field, the working conditions are harsh, and they are faced with the test of wind and sun, dust pollution and rain erosion. , hardness is a necessary prerequisite, so there are very strict requirements on coatings and their upstream polyester resins.
