  • IMPROVED CHEMICAL COMPOUNDS THAT UNDERGO REVERSIBLE CHANGES IN PROPERTIES AND USES THEREOF
    Publication number: 20170009052
    Abstract: Free radical scavengers, especially those that require the presence of oxygen, are useful in extending the life of photochromic, thermochromic, electrochromic, radiochromic, magnetochromic, photo-electrochromic and similar dyes. Particularly, preferred scavengers are the quinones be it O, M or p- and, most preferably, either the ortho, meta or para-hydroquinone. The so-enhanced dye can be used as a coating or cast as a film.

  • UV curable deck sealer
    Patent number: 6583195
    Abstract: A substantially 100% solids sealer composition for use with wood and, in particular, weathered wood surfaces and other porous surfaces is prepared from a mixture of UV curable acrylates and a photoinitiator blend. The composition may further include fillers, fungicides, insect repellents, animal repellents, UV light absorbers, pigments, dyes, and the like. The photoinitiator blend is used at relatively low levels to controll the degree of polymerization.

  • Finishing composition which is curable by UV light and method of using same
    Patent number: 5773487
    Abstract: A sprayable coating composition is formulated using one or more acrylates and one or more photoinitiators which act to polymerize the composition when exposed to ultraviolet light. Because of the use of low molecular weight monomers or oligomers, the composition is essentially free of volatile organic solvents, and therefore evaporative emissions in curing are substantially eliminated.
