Powder Coating Solutions for New Energy Battery and Energy Storage Equipment

With the explosive growth of the new energy industry, outdoor energy storage power stations, power battery cabinets, photovoltaic brackets, charging pile shells and wind power supporting equipment have put forward extremely strict comprehensive performance requirements for surface coatings. Different from ordinary industrial coatings, new energy equipment works in outdoor open environments for a long time, facing extreme conditions such as high temperature, low temperature, rain erosion, salt fog corrosion and strong ultraviolet radiation. At the same time, as electrical equipment, it must have excellent electrical insulation and flame retardant safety performance to avoid electric leakage, short circuit and fire hazards.

New energy special functional powder coating integrates five core performances: high electrical insulation, UL94 V0 grade flame retardancy, long-term salt spray resistance, wide temperature resistance and outdoor weather resistance. The formula adopts halogen-free environment-friendly flame retardants, high-resistivity insulating fillers, anti-aging agents and heavy-duty anti-corrosion pigments. It can form a dense and stable protective film on the surface of metal equipment, which not only isolates external corrosive media and delays equipment aging, but also effectively isolates current, prevents electric leakage accidents, and suppresses flame spread in case of equipment failure.

The production difficulty of new energy powder lies in the compatibility and uniform dispersion of multi-functional components. High-content flame retardant and insulating fillers are easy to cause poor powder fluidity, deteriorated spraying performance and brittle coating film. Improper process control will lead to unqualified flame retardant grade, insufficient insulation performance and poor weather resistance, which cannot pass industry safety certification. Therefore, professional customized production processes and equipment are required for supporting production.

TYOPSUN has developed a special production process for new energy insulating and flame-retardant powder. The segmented mixing process ensures full fusion of flame retardant, insulating and anti-corrosion components without component conflict and precipitation. The temperature-controlled twin-screw extrusion avoids thermal decomposition of flame retardant materials and ensures stable functional performance. The graded milling process optimizes powder particle size distribution, ensures excellent spraying fluidity and film-forming toughness, and avoids coating cracking and peeling.

The finished new energy powder has passed industry authoritative certification, with stable insulation performance, excellent flame retardant effect, salt spray resistance of more than 1000 hours and strong outdoor weather resistance. It is widely used in energy storage cabinets, battery shells, photovoltaic equipment and charging pile facilities, providing safe and durable surface protection for the new energy industry.
