Our proprietary formulas contain a mixture of various active ingredients, including UVA and UVB stabilizers. Such absorbent shows great stability in the protection of plastics, paint, rubber and polymers. In the case study for CarbonPro Sports, of the Carbon fiber material, in bicycle frames, parts and components, and their coats and sealants.
These fomulas are extremely efficient and capable of absorbing UV radiation of 290-400 nm( Nanometers) wavelength (entire UVA/ UVB Spectrum - also known as oxidative stress) without affecting the color light refraction especially in light colors. On the contrary, creating a protective coat, that will only increase after the continous use.
These formulas have the benefit of sharing in the water a microemulsion system with particle size up (<50 nm) designed to provide fast and effective protection to the surface.
Ultraviolet (UV) Radiation and its effects on painted surfaces, adhesives and coatings
The effect of UV induced degradation of painted surfaces often results in several different modes of damage. A critical mode is discoloration. This usually manifests itself by a yellowing or darkening of the adhesive or sealant. Color development, which may occur at widely differing amounts depending on the polymer, is also often accompanied by a loss in adhesive and coating properties.
The following pictures illustrate the effect of photodegradation on a polyurethane hot melt adhesive. Both samples were placed in a weatherometer for 12 hours at 65°C. After only 12 hours, the sample without the use of a UV absorber was already yellow.
For adhesives and sealants such as paints and coats, that may be used outdoors or in applications susceptible to UV attack, protection from discoloration is essential in maintaining the appearance and integrity of the bond or assembled part.
This is especially important in carbon fiber composites, as the UV attack can diminish the strength and consistency of the material; making it more vulnerable to scratches and breakage.
Even in regions where the temperature is rather low an there is not much sun activity, the UVA and UVB rays can still cause oxidation, as they can be reflected from the snow, the pavement, water, etc
