Category：Application industries, powder Coating | Brand：MT
Introduction
1. Product Features
(1) Excellent adhesion, flexibility, impact resistance, and high hardness.
(2) Based on the specific requirements of appliance powder coatings, we have refined the functional properties of the coating and incorporated additional functional elements according to different application requirements.
(3) Excellent electrostatic charging performance and sufficient flowability enable the powder to easily reach grooves, recesses, and hard-to-coat areas, overcoming the difficulty of powder deposition in these areas (reducing the Faraday cage effect).
(4) High powder utilization rate, high coating efficiency, and large spraying coverage area. Compared with traditional paint coatings, it offers lower coating costs. It complies with international standards and contains no toxic or harmful substances.
