Thermosetting coatings play an important role in the field of raw materials for chemical production, and their upstream and downstream related products are extensive. This article will detail the upstream and downstream related products of thermosetting coatings, including upstream raw materials, production equipment, and downstream applications.

1. upstream raw material

1. resin: the main component of thermosetting coating is resin, commonly used resin is epoxy resin, phenolic resin, amino resin and so on. These resins have good chemical resistance, heat resistance, electrical insulation and other properties, is an important part of thermosetting coatings.
2. Pigment: Pigment is an important additive in thermosetting coatings, mainly used to adjust the color and hiding power of the coating. Commonly used pigments are inorganic pigments and organic pigments, such as titanium dioxide, carbon black and so on.
3. Filler: Filler is an inert substance in thermosetting coatings, which mainly increases the coating volume, reduces the cost, and improves the hiding power. Commonly used fillers are calcium carbonate, talc, etc.
4. Solvent: Solvent is a volatile component in thermosetting coatings, which mainly plays a role in adjusting the viscosity of the coating and improving the construction performance. Commonly used solvents include benzene, alcohols, esters, etc.

2. production equipment

1. Mixing equipment: used to mix various raw materials of thermosetting coatings. Commonly used mixing equipment includes high-speed dispersing machine, sand mill, etc.
2. Filling equipment: It is used to fill the produced thermosetting coating into the packaging barrel. Commonly used filling equipment includes automatic filling line, manual filling machine, etc.
3. Testing equipment: used to detect the performance indicators of thermosetting coatings, such as viscosity, solid content, chemical resistance, etc. Commonly used testing equipment is viscometer, spectrophotometer, etc.

3. Downstream Applications

1. Construction: Thermosetting coatings are widely used in the construction field, such as interior and exterior wall coatings, waterproof coatings, etc., with excellent weather resistance, water resistance, stain resistance and other properties.
2. Automotive field: Thermosetting coatings are commonly used in the automotive field for body paint, chassis rust, etc., and have excellent corrosion resistance, wear resistance, decoration and other properties.
3. Home appliance field: Thermosetting coatings are commonly used in the field of home appliances, such as shell, internal parts, etc., with excellent heat resistance, electrical insulation, chemical resistance and other properties.
4. Petrochemical field: Thermosetting coatings are commonly used in storage tanks, pipelines, equipment, etc. in the petrochemical field, and have excellent oil resistance, chemical resistance, heat resistance and other properties.

In short, thermosetting coatings have a wide range of upstream and downstream related products in the field of chemical production raw materials, and their application fields are also very wide. With the continuous development of science and technology, the performance and application of thermosetting coatings will continue to expand.
