Introduction
1. Product Overview
Low-temperature curing powder coating is a newly developed product designed specifically for applications where high-temperature baking is unsuitable.
It not only retains the characteristics of conventional powder coatings but also reduces the curing temperature to 140~160℃, significantly expanding the application fields of powder coating technology.
