Dapro® UVAL 40

Modified long-oil alkyd dispersion with exceptionally broad compatibility, which offers 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. Can be used for 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. Available for use in most coatings vehicle systems. Recommended to use it in combination with hindered amine light stabilizers (HALS). These free radical scavengers have been demonstrated to provide synergistic effects with the ultrafine titanium dioxide. Recommended usage levels: 2.5-5% of it, 1-2% Ultrafine TiO2 as dry pigment, and 0.4% HALS on total coating weight.
