Paints and coatings undergo prolonged exposure to UV rays and need to be formulated to withstand the elements. “When it comes to withstanding sun and UV rays, color fade resistance is key,” says Camilo Quiñones, Market Segment Manager of Architectural Coatings at BASF.
Fig. 10, chemical degradation of the acrylic melamine coating exposed to full UV, 50°C and 70% RH is displayed. Difference T-FTIR spectra (Fig. 10a) show intensity decreases and increases in
Industrial UV resistant exterior paint. Ultra violet (UV) radiation is one of the main causes of fast deterioration of exterior paint. Constant exposure to UV light can lead to premature loss of colour and gloss as well as flaking and cracking of the coating. Therefore, nowadays, many exterior paints are UV protective as a standard. Also UV UV Protection. Acrylic roof coatings are highly reflective and UV resistant. These important qualities can save money by drastically reducing cooling costs during the hot summer months. Minimizing the sun’s impact on the roof surface not only helps sustain lower energy costs as the system ages but also cools internal building temperatures and
To achieve long-term performance, exterior coatings require resistance to degradation by UV radiation, resistance to hydrolysis, and resistance to erosion by rain and snow. The durability of a coating is typically assessed by exposing it at selected outdoor locations to quantify the coating’s real-world performance.
A fully cured surface of high-quality epoxy resin is extremely durable and abrasion-resistant. The material is mechanically very strong without deformation. It is also acid-resistant and not susceptible to corrosion. Therefore, high-quality resin is also used as a cut-resistant coating for kitchen worktops. Possible Disadvantages of using Resin
Vinyl acrylic binders are supposed to match the all-acrylic emulsions in gloss and tint retention. VAE products are acclaimed for scrub resistance. Styrene acrylics are promoted for gloss, chemical resistance and dirt pickup resistance. The exterior performance claims for the nonacrylic binders raise two issues.
