ZC6546：Preferred High-hardness Polyurethane UV Topcoat for Vacuum Plating Applications

ZC6546 is a four - functional solvent - based polyurethane acrylate that offers a remarkable set of properties, making it a highly sought - after material in various coating applications.

Key Features and Benefits

1. Excellent Adhesion

• ​​Strong Bonding to Substrates​​: ZC6546 exhibits excellent adhesion properties, enabling it to firmly attach to a wide variety of substrate surfaces. This ensures that the coating remains stable and does not easily peel off, even under normal use or exposure to external forces. Whether it is a smooth or rough surface, ZC6546 can form a reliable bond, providing a solid foundation for the coating.
• ​​Enhanced Coating Durability​​: The strong adhesion of ZC6546 contributes to the overall durability of the coating. It helps the coating withstand various environmental factors such as temperature changes, humidity, and mechanical stress, ensuring long - term protection and performance of the coated product.

2. High Hardness

• ​​Outstanding Wear and Scratch Resistance​​: With its high hardness, ZC6546 provides excellent wear and scratch resistance. This property is crucial for protecting the underlying substrate from damage caused by daily use, such as abrasion from contact with other objects or cleaning processes. The hard coating acts as a shield, maintaining the integrity and appearance of the coated product over time.
• ​​Improved Product Longevity​​: By offering superior protection against wear and scratches, ZC6546 extends the lifespan of the coated products. This is particularly important in applications where the products are subject to frequent handling or exposure to harsh conditions, ensuring that they remain in good condition and retain their aesthetic appeal.

3. Excellent Gloss and Color - Rendering Properties

• ​​Uniform and Full - bodied Color​​: ZC6546 has outstanding gloss and color - rendering properties, which allow the coating film to have a more uniform and full - bodied color. This enhances the visual appeal of the coated product, giving it a high - quality and professional look. Whether it is a matte or glossy finish, ZC6546 can achieve the desired color effect with precision.
• ​​Accurate Color Representation​​: The excellent color - rendering ability of ZC6546 ensures that the true colors of the pigments are accurately presented. This is essential in applications where color accuracy is critical, such as in the automotive, consumer electronics, and cosmetic industries. It allows for consistent and vibrant color reproduction, meeting the high - quality standards of these industries.

4. Good Color Development

• ​​Precise Pigment Color Presentation​​: ZC6546 demonstrates good color development, which means it can precisely present the colors of the pigments. This property is important for achieving the desired color effects in coatings, especially when using different types of pigments or color combinations. It allows for fine - tuning of the color to meet specific design requirements, ensuring that the final product meets the aesthetic expectations of the end - user.

5. Excellent Resistance to Hand Sweat and Boiling Water

• ​​Stability in Complex Environments​​: ZC6546 has outstanding resistance to hand sweat and boiling water, which is a significant advantage in daily use scenarios. Even when exposed to the moisture and salts present in hand sweat or subjected to the high temperatures of boiling water, the coating can maintain its performance and stability. This ensures that the coated products remain in good condition and retain their functionality and appearance over time.
• ​​Long - term Protection in Harsh Conditions​​: The excellent resistance to hand sweat and boiling water of ZC6546 provides long - term protection for the coated products in harsh environments. It prevents issues such as discoloration, peeling, or degradation caused by exposure to moisture and heat, ensuring the durability and reliability of the products.
