Title:
PRECISE CONTROL OF SURFACE TEXTURE OF ULTRAVIOLET RAY CURAB-LE SUBSTRATE
Document Type and Number:
Japanese Patent JPS5959270
Kind Code:
A
Abstract:
The present invention relates to a three-stage UV curing process whereby a UV-curable substrate is initially exposed to long wave length light of low intensity, thereby causing the bottom portion of the substrate to gel while leaving the top surface essentially unaffected. The first stage irradiation is followed by irradiation with shorter-wave length UV light under an inert atmosphere, thereby causing the surface of the substrate to gel. The final stage of the curing process involves conventional exposure to strong UV light whereby the entire structure is cured to give a product having finely controlled surface texture. The resulting products are useful as surface coverings, and particularly as floor and wall coverings.
