With the increase in the types of decorative materials on the market, many people have begun to pay attention to the environmental performance of decorative profiles, and dry powder paint used for indoor use is one of them.
Compared with traditional solvent-based paints, dry powder paints are more energy-saving and environmentally friendly, and the construction process is relatively simple. So what are the types of dry powder paints? What are their characteristics?
Thermosetting dry powder coating
This type of dry powder coating uses thermosetting resin and curing agent to heat and cure to form an insoluble, infusible, hard coating film.
Since the resin used in thermosetting dry powder coating has a low degree of polymerization, it has good leveling and decorative effects after construction, good anti-corrosion, and mechanical properties, and the coating is not easy to soften no matter how high the temperature is, but only decomposes.
Thermosetting dry powder coatings are mainly divided into polyester powder coatings, acrylic powder coatings, and epoxy powder coatings.
Thermoplastic dry powder coating
The main raw material of this dry powder coating is a common polymer, and its performance can well meet the needs of consumers.
Thermoplastic dry powder coating is simple to process, easy to spray, and can form a film after cooling, and its application range is very wide.
However, thermoplastic dry powder coating has a high melting point, low coloring, and poor adhesion to metal, which leads to certain restrictions on its application.
Thermoplastic dry powder coatings mainly include polyethylene powder coatings, polyvinyl chloride powder coatings, nylon powder coatings, fluoro resin powder coatings, fluoro resin powder coatings, etc.
Environmentally friendly and non-toxic
Dry powder coating is a material that does not volatilize any harmful substances. It is a non-toxic, fireproof, and waste-free environmentally friendly building material.
Recyclability
Dry powder coating is the product with the highest utilization rate among all building material coatings. It is sprayed during construction, and the remaining powder after spraying can be recycled and reused, with a utilization rate of more than 99%.
Automated operation
When construction workers use dry powder spraying, the work is completed in one go, no primer is required, and the coating thickness is guaranteed. Due to these characteristics, dry powder spraying can be automated, thereby reducing costs and improving efficiency.
Excellent performance
Dry powder coating is easy to apply and can cover corners well. The coating has good adhesion, good density, strong impact resistance, high toughness, excellent corrosion resistance, and electrical insulation.
Convenient storage and transportation
Compared with solvent-based paints, dry powder paints are safer and more convenient to store and transport, while solvent-based paints need to be transported with great care and will evaporate.
