Title:
PHOTOCURABLE RESIN COMPOSITION FOR LINING MATERIAL, PHOTOCURABLE LINING MATERIAL AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/070816
Kind Code:
A1
Abstract:
Provided is a photocurable resin composition for a lining material, the composition being characterized by containing: (A) a resin component containing (a1) a carboxyl group-containing epoxy (meth)acrylate and (a2) an unsaturated monomer as essential components; (B) a thickening agent; and (C) a photopolymerization initiator. This photocurable resin composition for a lining material exhibits suitable thickening behavior and excellent curing properties and can yield a cured lining material product having excellent bending strength, tensile elongation and heat resistance, and can therefore be advantageously used for renovating pipes such as sewer pipes.
