1. Environmental protection policies promote the great development of powder coatings
Powder coating is a kind of solid powder 100% coating, it is different from the general solvent-based coating and water-based coating, not the use of solvent or water as a dispersion medium, but with the help of air as a dispersion medium. It has no volatiles produced, easy to clean, no solvent, little harm to the operator, high utilization rate of spraying, excellent performance and so on.
With the increasing global attention to environmental protection, powder coatings are being applied more and more widely. It is worth noting that the use of powder coatings in China has exceeded 1 million tons, and the market is expected to reach 15 billion US dollars by 2026, with a compound annual growth rate of 6.8%.

2. New development trend of powder coating -- high temperature resistant powder coating
With the development of home building materials industry, China has gradually become the world's main production base for cookware, ovens, exhaust pipes and other equipment. The market demand for high temperature resistance of coating surface is more and more intense, while the general powder coatings on the market have low long-term temperature resistance. When the high temperature is 200 ℃ or above, the coating will appear fading, yellowing and chalking. This promoted the development of powder coatings to high temperature resistant powder coatings.
High temperature resistant powder coating is a kind of special functional powder coating, generally refers to the powder coating can withstand the temperature above 200℃ called high temperature resistant powder coating, according to the temperature is different, generally divided into 200℃, 300℃, 350℃, 400℃, 500℃ and above, Widely used in roasting oven, braising furnace, heating machine, heating pipe, muffler, oven, vehicle exhaust pipe, chimney and other equipment.
Because of the advantages of high temperature resistant powder coating in environmental protection, safety, utilization and other aspects, it will gradually replace the traditional high temperature paint.

3.IOTA GT silicone powder
Product characteristics
Pure silicone resin has excellent high and low temperature properties, arc corona resistance, electrical insulation and moisture resistance. Its weathering resistance, high mechanical properties, flame retardant, corrosion resistance, ozone resistance and chemical stability is very excellent. The resin is used for various high temperature resistant equipment coatings, high temperature anticorrosive coatings, powder coatings, insulating materials, weather resistant coatings, ink and other special environment coating protection. GT5 has high glass transition temperature and superior high temperature resistance.

application
Used as high temperature resistant powder coating or liquid resin. Can also be used with epoxy, polyester and other powder resin; Such as barbecue grill, muffler, exhaust pipe and other need high temperature anticorrosive coating, insulation materials or spacecraft, military equipment fields.

Usage method
A thermosetting composite system is prepared with silicone solid resin as the base material, mixed with filler, pigment, curing agent, auxiliary agent or glass fiber, etc., and can be processed by transfer molding, electrostatic spraying and solvent based methods.

advantage
1. No solvent, fully meet the requirements of environmental protection;
2. No sticking at room temperature, powder storage does not caking;
3. Can be mixed with IOTA GT3 to get different performance products;
4. High temperature resistance fluctuates slightly with different formulations, up to ≥700 degrees.
