▎ 摘 要
NOVELTY - A composition comprises a combination of resin (24) and graphene material (22). USE - Composition used for forming product and composite such as boat hull, pipe, swimming pool, spa, tank, storage vessel, cladding, roof material and concrete pipe line (all claimed). ADVANTAGE - The composition prevents the damage of product and composite by hydrolysis which causes cracking and increases lifetime of the product. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) product which comprises structure containing composition; (2) manufacture of product which involves coating the composition with a colored gel coat and coating top coat; and (3) water-resistant composite which comprises matrix of graphene material and resin. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of moisture diffusion into composite result in degradation.
