Low density Polyester varnishes compound metal powder for coatings
A thermosetting powder coating based on epoxy polyester resin with excellent smooth glossy and
good flowout finishes.
Its outstanding overbake yellowing resistance and mechanical properties make it a wide range of indoor
applications as domestic appliances, home and office furniture,light fixtures, shelvings, machinery, ceiling panels,
Texture finish available too.
The raw materials of Powder coating are resins, pigments, fillers, harderner ect. Compared with lyquid paint, powder coating is environmental friendly and can reduce costs. Powder coating can form a harder finish than conventional paint and can be applied more efficient. While it also has disadvantages, it is not good for large amd heat-sensitive objects. Usually the thickness of film by powder coating is >30 μm.
Technic Data: Specific gravity: 1.2-1.8 ( depend on colors) Particle size distribution(Laser Particle size analyser): Less than 5% above 100μm;
50-65% above 32 μm Average particle size:35-45 μm Curing Schedule: 200°C 10minutes (metal temp) Optimal film thickness: 60-80μm 8-12 square meters, thickness 60μm(100% of utilization rate) The data above is rough and for reference only.
More information will be confirmed seperately.
