Description: Polyester Acrylate 5501 is a high-performance UV resin with excellent compatibility with most UV monomers and UV resins. Owing to its outstanding balance of properties, it has become a fundamental resin in LED-UV wood coating systems.
One of the most prominent features of 5501 is its low viscosity and high solids content, which provides greater flexibility in formulation. This ensures smooth application while simultaneously increasing solid content and reducing solvent usage, achieving the perfect balance between performance and environmental responsibility.
The resin also offers fast curing speed, particularly under LED-UV light sources. This enables rapid film formation, significantly boosting production efficiency and energy savings—meeting the modern wood coating industry’s demand for speed and sustainability.
In terms of film properties, 5501 delivers excellent leveling, creating smooth and uniform coatings free from pinholes, orange peel, and surface irregularities. Combined with its good sandability, it supports multi-layer coating processes with ease, ensuring flat, refined, and visually appealing finishes.
Furthermore, 5501 exhibits superior pigment affinity and substrate wettability, enhancing pigment dispersion and stability for brighter, more consistent colors, while also improving adhesion to wood substrates for long-lasting durability.
With its exceptional curing performance, aesthetic benefits, and robust processing properties, Polyester Acrylate 5501 stands out as the resin of choice for LED-UV wood coating systems. Choosing 5501 means achieving coatings that are not only efficient and eco-friendly but also elegant and durable.
