Product Description
• Low Viscosity and Easy Application: A4025 has a low viscosity range of 300-800 mPa.s at 25°C, making it easy to apply and ideal for applications requiring a thin, even coating.
• High Toughness and Wear Resistance: With a Shore hardness of 93 and a pencil hardness of 3H, A4025 provides a tough, durable finish that is resistant to wear and scratches. This makes it perfect for high-traffic areas such as flooring and wood coatings.
• Excellent Yellowing Resistance: A4025 shows impressive resistance to yellowing, with initial yellowing at 800 mj/cm² measured at 0.64 and final yellowing at 8000 mj/cm² measured at 2.45. This ensures long-lasting clarity and aesthetic appeal.
• Fast Curing Speed: The resin cures quickly at 200 mj/cm², enhancing production efficiency and reducing downtime in manufacturing processes.
• Strong Adhesion to Plastics: A4025 demonstrates excellent adhesion to ABS and PC substrates with a 5B adhesion rating, ensuring a secure bond for durable and long-lasting coatings. However, it shows limited adhesion to aluminum surfaces.
• Slight Odor Post-Curing: After curing, A4025 emits a mild odor, which is considered acceptable in most industrial environments.
Applications
• Rigid PVC Flooring Coatings: A4025 is ideal for use in coatings on rigid PVC flooring, providing a durable, wear-resistant finish with a gloss level within 5 degrees, ensuring a visually appealing and long-lasting surface.
• UV Spray Coatings and Varnishes: The resin’s low viscosity and fast curing properties make it suitable for UV spray coatings and varnishes, delivering a smooth, even finish with excellent leveling.
• High-Hardness Wood and Flooring Coatings: With its high hardness and wear resistance, A4025 is recommended for wood and flooring coatings that require a tough, scratch-resistant surface with excellent resistance to yellowing and abrasion.
Conclusion:
The A4025 polyurethane acrylate resin is a robust solution for manufacturers seeking a resin with low viscosity, high toughness, and superior adhesion to plastics like ABS and PC. Its fast curing speed, excellent yellowing resistance, and durability make it an ideal choice for a wide range of applications, including rigid PVC flooring, UV spray coatings, and high-hardness wood finishes.
