Flexible luminescent paints patented

Flexible luminescent paints patented Source: Jinan Chenghao Technology Co., Ltd.

Flexible luminescent paints are prepared from physical blends of hybrid epoxy acrylic resins, cementicious acrylic resins and optionally pure acrylic coating resins together with monopropylene glycol, suspension additives, rheological additives and photoluminescent pigments. The luminescent paints exhibit bright, even and long-lasting photoluminescent afterglow, excellent flexibility in both thin and thick layers, and are suitable for spraying, brushing, rolling and screen printing. Optional fluorescent pigments may be utilized to give daylight coloration and up-convert the photoluminescent emissions to the fluorescent emissions color. Extensive testing was conducted with thin metal panels coated with the paint and vinyl screen sheet printed with paint, with the paint in all cases in excess of 1 mm thick. The metal panels and vinyl screens withstood constant bending through 90 degrees in both directions without any cracking to the coating, with adhesion being maintained to the surface. The flexible luminescent paints may be applied, for example, to wood, metal, concrete and vinyl as the inventor John Russell Robinson explains.
