Description:
Quantities of UVT materials were produced for incorporation into UV curable coating formulation. The UVT materials produced included fused quartz powder and borosilicate glass microspheres. A clear epoxide based UV curable coating was formulated as a control. White and black control formulations were derived from the clear formulation by the addition of titania and carbon pigments respectively. Trial coating of these formulations with and without the addition of UVT materials were applied to aluminum and plywood substrates for curing with synthetic and natural UV light. The trial coating were evaluated for time to cure, degree of curing, hardness, and adhesion.Summary/Accomplishments (Outputs/Outcomes):
Marginal improvements in cure time was observed for the white and black formulations with the addition of UVT materials over the control formulation. Addition of UVT materials to the pigmented formulations suppressed wrinkling of the surface observed in the control coatings cured under synthetic UV. Also, a noticeable off-white tan color evolved in the white control coatings when cured under both natural and synthetic UV. The addition of UVT materials to the white formulations suppressed the appearance of this tan color. However none of the pigmented formulations resulted in an acceptable coating based on comparisons to the clear control coating.Conclusions:
Improvements in the cure time and surface quality was observed for coatings incorporating UVT materials. However, no significant improvements in the hardness and adhesion of the UVT coatings was observed over the standard formulations. Commercialization is not considered feasible at this time without additional development of the technology.Supplemental Keywords:
