Claims30
A method of coating a cementitious substrate, the method comprising:
- causing a wet look coating composition to be applied to at least a portion of the cementitious substrate to provide a hardened wet look coating, the coating composition comprising:
- a multistage latex polymer comprising an emulsion polymerized first stage and an emulsion polymerized second stage;
- wherein the multistage latex polymer has an overall Fox equation Tg of at most 5° C. and comprises:
- interpolymerized monomers comprising diacetone acrylamide (DAAM);
- and
- at least one stage having a measured Tg of at least 60° C.;
- wherein the composition comprises less than 100 g VOC/L, according to ASTM D6886-2018.
A method of coating a cementitious substrate, the method comprising:
- causing a wet look coating composition to be applied to at least a portion of the cementitious substrate to provide a hardened wet look coating, the coating composition comprising:
- a multistage latex polymer comprising an emulsion polymerized first stage and an emulsion polymerized second stage;
- wherein the multistage latex polymer comprises:
- interpolymerized monomers comprising diacetone acrylamide (DAAM);
- at least one stage having a measured Tg of at least 60° C.;
- and
- core-shell polymer particles, wherein a chain transfer agent is in the shell of the core-shell polymer particles;
- wherein the composition comprises less than 100 g VOC/L, according to ASTM D6886-2018.
A low VOC aqueous wet look coating composition, the composition comprising:
- a multistage latex polymer comprising an emulsion polymerized first stage and an emulsion polymerized second stage;
- wherein the multistage latex polymer has an overall Fox equation Tg of at most 5° C. and comprises:
- interpolymerized monomers comprising diacetone acrylamide (DAAM);
- greater than 1 wt-% of a chain transfer agent, based on the total weight of monomers used to form the multistage latex;
- and
- at least one stage having a measured Tg of at least 60° C.;
- wherein the composition comprises less than 100 g VOC/L, according to ASTM D6886-2018.
A method of coating a cementitious substrate, the method comprising:
- causing a wet look coating composition to be applied to at least a portion of the cementitious substrate to provide a hardened wet look coating, the coating composition comprising:
- a multistage latex polymer comprising an emulsion polymerized first stage and an emulsion polymerized second stage;
- wherein the multistage latex polymer comprises:
- interpolymerized monomers comprising diacetone acrylamide (DAAM);
- at least one stage having a measured Tg of at least 60° C.;
- and
- core-shell polymer particles, wherein the shell of the core-shell particles is formed from components comprising one or more chain transfer agents;
- wherein the composition comprises less than 100 g VOC/L, according to ASTM D6886-2018.
