Abstract
A method of coating a concrete floor is disclosed in which the concrete surface is coated with a homogeneous liquid coating composition containing maleate or fumarate unsaturation in combination with vinyl ether unsaturation and a ketonic photoinitiator, the wet coating is allowed to seep into the concrete surface and to flow out on the concrete surface to form a smooth coating, and this coating is cured by exposing it at light having a wavelength in the range of from about 200 to about 600 nanometers.
Claims19
A method of coating a concrete floor comprising coating said floor with a homogeneous liquid coating composition comprising a vinyl ether monomer, oligomer or polymer;
- a polyethylenic maleic or fumaric polyester and a ketonic photoinitiator, allowing the wet coating to seep into the concrete surface and to flow out on the concrete surface to form a smooth coating, and curing said coating by exposing the same to light having a wavelength in the range of from about 200 to about 600 nanometers.
A method of coating a concrete floor comprising coating said floor with a homogeneous liquid coating composition comprises a blend of a polyvinyl ether oligomer and a maleic or fumaric-unsaturated polyester, the equivalent ratio of the vinyl ether and maleate or fumarate groups being in the range of about 3:1 to about 1:3, and an hydroxy or alkoxy-functional acetophenone derivative or a benzoyl diaryl phosphine oxide as photoinitiator, allowing the wet coating to seep into the concrete surface and to flow out on the concrete surface to form a smooth coating, and curing said coating by exposing the same to light in the range of from about 200 to about 600 nanometers.
Concrete coated with a photocured homogeneous liquid coating composition containing maleate or fumarate unsaturation in combination with vinyl ether unsaturation and a ketonic photoinitiator.
