Abstract
Described is a UV-curable sealant composition, which is preferably a one part sealant. The one part sealant is made from urethane acrylate, acrylate ester, precipitated silica, and photoinitiator. More specifically, the one part sealant is made from about 15-35 weight percent aliphatic and/or alicyclic urethane acrylates, about 40-70 weight percent of acrylate esters, about 0-10 weight percent of precipitated silica, and about 3-8 weight percent of photoinitiator. Also described are methods of applying UV-curable sealant composition to a surface such as a floor and UV curing the UV-curable sealant composition, thereby extending the life of the surface.
Claims16
A sealant composition comprising an admixture of about 15-35 weight percent of aliphatic and/or alicyclic urethane acrylates, about 40-70 weight percent of acrylate esters, about 0.5-10 weight percent precipitated silica, and about 3-8 weight percent photoinitiator.
A one part UV-cured sealant composition comprising about 15-35 weight percent of urethane acrylate, about 40-70 weight percent of acrylate ester, about 0.5-10 weight percent precipitated silica, and about 3-8 weight percent photoinitiator, wherein the one part UV-cured sealant composition has been applied to a surface and cured by UV-radiation at a wavelength that initiates said photoinitiator to cure the UV-cured sealant composition.
