A detailed description

Product introduction

Product Application Features

The performance of water-based hot-melt PVDF coatings has reached (PVDF) fluorocarbon coatings (HG3793-2005) and American (AAMA-2605) standards.

The water-based hot-melt PVDF coating has been tested in the laboratory, and the performance of the professional spray gun has fully met the requirements of the end customer.

Convenient: no need to use hazardous chemicals solvents, diluted directly with water when using;

Safety: high flash point, non-flammable, non-explosive, non-corrosive, and not a hazardous chemical;

Environmental protection: Ultra-low VOC direct emissions, solving the problem of environmental protection emission inspection, without using combustion emissions;

Energy saving and emission reduction: The production process does not produce irritating odor and smoke, and the baking temperature of the paint film is reduced to 195 ± 5 ° C, which achieves the purpose of energy saving and emission reduction.

Easy to spray: suitable for a variety of water-based spray equipment such as Japanese blue, French SAMES
