Valve Powder Coating
Characteristics of Valves
Valves typically have the following characteristics:
Thick and uneven walls
Irregular shapes
Rough surfaces
High thermal inertia, leading to slow temperature rise
Severe collisions during handling
Due to these characteristics, using conventional powder coatings often results in various issues. Our company has developed a specialized powder coating for valves through material selection and experimentation. This valve-specific powder coating not only offers the usual decorative appeal but also has the following outstanding features:
Excellent Adhesion, Impact Resistance, and Surface Scratch Resistance: The coating will not be damaged during normal handling and collisions of valves.
Low-Temperature Curing: The baking conditions are 160°C for 15-20 minutes or 180°C for 10 minutes. Compared to conventional powder coatings that require 180°C for 15-20 minutes, this coating improves spraying efficiency and saves energy.
High-Gloss Coating: The high-gloss powder coating for valves has excellent leveling properties, no sagging, good coverage, and excellent edge coverage. The coating thickness can be around 100 µm.
Defoaming for Cast Iron Valves: This coating effectively addresses defoaming issues for cast iron valves.
Improved Powder Transfer and Coverage: By adjusting the powder particle size and introducing new materials in the formulation, the Faraday cage effect is mitigated, resulting in better powder transfer and larger coating area.
Customizable Gloss and Texture: The coating can be tailored to meet customer requirements for various gloss levels and textures.
