Dapro® Ultraviolet Stabilizers
Ultrafine Titanium Dioxide Dispersions (Non-Pigmentary)
Dapro Ultraviolet Stabilizers are ultrafine titanium dioxide dispersions which offer protection to the film and substrate in clear coatings. Ultrafine titanium dioxide is 1/10th of the particle size of white (pigmentary) TiO2, and therefore, smaller than the wavelength of visible light. The particles absorb, scatter and reflect UV light, hence the UV protection.
The primary uses for these products are clear wood coatings, colored transparent wood finishes and clear coatings from which organic UV absorbers have a tendency to migrate and sublime. Examples would be aircraft finishes, coatings on plastic, and deck finishes.
Dapro Ultraviolet Stabilizers are available for use in most coatings vehicle systems. UVCW 30 is an aqueous formulation for use in high-performance waterborne coatings. UVAL 40 is a modified long-oil alkyd dispersion with exceptionally broad compatibility. UVST 35 is based on a modified thermoplastic acrylic compatible with most solventborne, high-performance coatings.
It is recommended that Dapro Ultraviolet Stabilizers be used in combination with hindered amine light stabilizers (HALS). These free radical scavengers have been demonstrated to provide synergistic effects with the ultrafine titanium dioxide. Normal levels of use are 1-2% Ultrafine TiO2 as dry pigment, and 0.4% HALS on total coating weight.
