Epoxy Modified Acrylic Dispersion Resin Salt Spray Resistance For Hardware Coatings

WL-AD398 is an epoxy-modified hydroxyl acrylic dispersion with excellent salt spray resistance, good adhesion to various substrates, and thixotropic properties. After reacting with isocyanate curing agent, epoxy modified acrylic dispersion forms a 2K PU coating with high cross-linking density, which has higher hardness, wear resistance, impact resistance, excellent adhesion, chemical resistance, and weather resistance. WL-AD398 is specifically designed for matte coatings, and is highly recommended for hardware coatings.

WL-AD398 provides long-lasting corrosion protection in high-humidity and high-salt environments. It also exhibits strong adhesion to various substrates, including metals and plastics. Its thixotropic property improves application performance, reducing sagging and ensuring uniform coating on vertical surfaces. In addition, it is of water-based system, and provides matte finish, which makes the coating compliant with environmental regulations, and offering low-gloss and aesthetically pleasing appearance.

These characteristics make WL-AD398 an excellent resin choice for 2K PU hardware coating, particularly in demanding environments. By utilizing WL-AD398, hardware coating can achieve superior corrosion protection, durability, and aesthetic appeal, meeting the demands of both functional and decorative applications.

For instance, it could be utilized in the preparation of 2K PU paint for metal tools like wrenches and pliers. Its salt spray resistance could protects tools from corrosion in humid or salty environments. Its adhesion also ensures the coating firmly adheres to metal surfaces, preventing peeling. The thixotropy facilitates uniform coating on complex-shaped tools, reducing sagging. The matte finish provides a professional, non-reflective appearance to the tools. Apart from metal tools, it is this resin based 2K PU is also applicable in metal furniture, architectural hardware (e.g., door handles, balcony railings, window frames), and decorative hardware like lamps, ornaments, fixtures.
