With the advancement of technology, electronic products are not only becoming more diverse but also increasingly intricate. Addressing these high-end requirements, we introduce our water-based two-component polyurethane coating specifically designed for electronic devices. This coating blends the durable and flexible properties of polyurethane with the environmental benefits of water-based paints. With its exceptional adhesion, swift curing times, and superior resistance to chemicals, it ensures your electronic products always radiate a rich fusion of technological and contemporary hues.
●Primer Coating:
This primer lays a solid foundation for electronic products, strengthening adhesion and
ensuring the durability and integrity of the subsequent layers. Using water as its primary
solvent, it significantly reduces harmful VOC emissions, making a positive environmental
contribution.
● Colored Coating:
Specially designed for electronic items, our colored coating offers a variety of trendy color
options to meet the diverse needs of consumers. Its rapid drying and lasting characteristics
further optimize production efficiency, ensuring products always shine like new.
●Clear Coating:
Our clear coat offers a diverse range of finishes to cater to your needs, from sleek glossiness
to subtle matte. This coating not only safeguards electronic products from scratches and
wear but also ensures they always present a polished and elegant appearance. Whichever
style you choose, it highlights the product's premium feel and enduring allure.
