What are the characteristics of low-temperature curing powder coatings
source：www.cnjindu.com | Release time：2026年07月15日1. Low baking temperature, suitable for thermal sensitive substrates
The curing conditions for ordinary powder coatings are generally 180-200 ℃; The low-temperature baking temperature has been lowered to 120-160 ℃.
Can spray aluminum alloy thin materials, plastic parts, fiberglass parts, PCB boards, wood, paper composite boards;
For previous wire and die cast aluminum parts: thin aluminum materials should avoid high-temperature deformation, prevent high-temperature oxidation of workpieces, and be suitable for subsequent spraying of precision rolled products.
2. Save energy consumption and reduce production costs
Reduce energy consumption during oven heating; Shorten the heating and insulation time, and shorten the curing time from 15-20 minutes to 8-12 minutes;
The power consumption and natural gas consumption of the production line have decreased, improving the output speed of the assembly line and enhancing the production rhythm of the chain plate line.
3. Excellent comprehensive performance of the coating film
Good coating adhesion, excellent impact resistance and bending performance; The finished product is resistant to salt spray, moisture and heat, and oil stains;
Resistant to chemical solvents and corrosion from cleaning agents; Outdoor formula is UV resistant and not easily faded after long-term use;
The surface is smooth and delicate, with less orange peel, and has a good appearance texture. It can achieve high gloss, matte, and sanding effects.
4. Outstanding environmental characteristics (shared by powder coatings+advantages of low-temperature formula)
No solvents, no VOCs, no volatile harmful substances; Compliant with domestic environmental standards; No exhaust emissions during the production process;
Overloaded powder can be recycled and reused, with a material utilization rate of over 95%; Compared to liquid paint, it significantly reduces solid waste;
The curing process does not release gas and is suitable for factory enclosed workshops and machine vision production line environments.
5. Strong production adaptability
Existing electrostatic spraying equipment can be used without the need for large-scale modification of spraying machines;
Controllable coating thickness (40-120 μ m); Good coverage of edges and corners, and even powder coating on the edges and corners of wire accessories and stamped parts;
It can be combined with automated assembly lines and chain plate conveyor lines to achieve batch continuous production.
2、 There are limitations
The cost of raw materials is higher than that of conventional high-temperature powder coatings, and special low-temperature curing resins are selected for the resin system;
Strict storage requirements: It needs to be stored in a cool environment below 25 ℃, and the powder is prone to clumping in high-temperature warehouses;
Strict control of baking parameters: When the temperature does not reach the set value, the coating curing is incomplete, resulting in insufficient hardness and paint peeling problems. Higher temperature control accuracy is required during production;
Low temperature powders are not suitable for environments with high temperature resistance and long-term working conditions (above 200 ℃).
3、 Mainly applicable industries
Precision hardware industry: rolling mill accessories, photovoltaic welding strip accessories, aluminum alloy die-casting parts, wire components;
Medical device accessories: metal components of staplers;
Electronics industry: PCB components, shells, precision sheet metal parts;
Furniture industry: MDF density board, wooden board;
Equipment casing: automation equipment sheet metal, chain plate line rack, instrument casing.
