Abstract
This invention relates to coating compositions that include water; a latex polymer and a silane coupling agent. The latex polymer preferably comprises acetoacetoxy functionality, or is a multistage latex, or is an acetoacetoxy functional multistage latex. The silane coupling agent is preferably a functionalized silane coupling agent (more preferably an epoxy-functional silane coupling agent). The compositions may be used to coat a variety of substrates, including wood, cement and fiber cement. Articles having the coating applied thereto are also provided.
Claims20
A coating composition, comprising:
- water;
- a multistage latex polymer having acetoacetoxy functionality;
- and
- at least about 0.25 weight % and less than about 10 weight %, based on the weight of the latex polymer solids, of an epoxy-functional silane coupling agent that improves adhesion of the coating composition to a cementitious substrate.
