The surface coating treatments for PU waiting chairs are generally divided into two types: ordinary paint film and anti-fouling coating:
Ordinary paint film
During the production process of PU waiting chairs, a single layer of paint film needs to be sprayed on the surface of the product to ensure the uniformity and beauty of the product's color. However, since the traditional process does not add a new coating for protection, the anti-seepage and anti-fouling of its products are difficult to guarantee.
After the PU waiting chair is sprayed with a paint film, its epidermis is similar to human skin, with tiny micropores that are invisible to the naked eye. These densely packed micropores on the surface are very likely to leak during use, causing the surface to be contaminated.
Its waiting chair has the following disadvantages:
1. Not anti-seepage, easy to cause bacteria: When cleaning the surface, water easily penetrates the paint film to breed bacteria, causing the surface of the PU waiting chair to mold and discolor.
2. Not resistant to dirt: After long-term use, the small micropores on the surface of the PU surface film are easy to hide dirt and form stains that are difficult to clean, affecting the aesthetics of the product
3. Affecting the service life: The PU surface is easy to breed bacteria and mildew and easy to hide dirt. After long-term use, its surface tissue is easy to change, causing the PU surface to age and fade, which has a certain impact on its service life.
Anti-fouling coating
After years of research, a new breakthrough has been achieved in the preparation process of the anti-fouling coating of the PU waiting chair. A dense anti-fouling coating with a thickness of 5μm~10μm is added to the surface of the PU waiting chair using polymer materials.
Its waiting chair has the following advantages:
1. Anti-penetration and anti-mildew. After the PU surface is treated with a coating, it has a certain waterproof function and is not easy to breed bacteria. It is difficult to mildew within the normal service life, ensuring the service life of the product.
2. Wear-resistant and dirt-resistant. The PU surface coating is tightly attached to the PU surface, which has a certain protective effect on the PU surface film, greatly improving the wear resistance of the product, and at the same time, it is not easy to produce stains on the surface of the product.
2. Not easy to fade, not easy to stain, easy to clean. Since the anti-fouling coating on the PU surface has the characteristics of anti-penetration, dust, water stains, oil stains and other dirt on the PU surface can be cleaned with ordinary furniture cleaners. In addition, the anti-fouling coating also protects the paint from fading caused by oxygen aging, allowing the product to maintain bright colors for a long time.
