Product Description
This product is synthesized by epoxy and polyester resin, with special properties
of the two materials, with advantages of excellent decorative effect, mechanical
properties and high corrosion resistance. It is widely used in metal lanterns
decoration as following:
•lantern decoration: ceiling lamp, table lamp, fluorescent light, energy-saving lamp,
flood light, explosion proof light, signal lamp, indoor light, outdoor light, wall light,
ground light, pendant light, down light, spot light, yard lamp, road light;
•we offer powder coatings with different colors, gloss and textures.
