1. Basic Product Overview

Acrylic/polyester powder coatings are characterized by their heat resistance, low-temperature curing ability, and excellent resistance to yellowing. This provides an innovative solution suitable for various applications, including reflectors for lighting fixtures, building materials, and road materials. 

2. Technical Details

This product overcomes the issues of block resistance during the curing of urethane-cured polyester resin-based powder coatings and the corrosion resistance and cost challenges of acrylic resin-based powder coatings through the reaction and curing of polyester resins containing carboxyl groups with acrylic resins containing glycidyl groups. This hybrid coating, which can cure at low temperatures of 160°C, has successfully reduced volatile organic compounds and excels in heat-resistant yellowing. 

3. Advantages

Acrylic/polyester powder coatings can reduce energy consumption due to their low-temperature curing ability. Moreover, their superior resistance to heat-induced yellowing ensures long-term maintenance of aesthetics. 

4. Disadvantages

However, due to the inclusion of acrylic resin, these coatings may be more expensive compared to conventional paints.
