Abstract
Resin compositions having a reduced solubility and methods for making and using same are provided. In at least one specific embodiment, the resin composition can include a phenolic resin, a latent acid, a catalyst, and a liquid medium. The catalyst can be a base compound and can be present in an amount of about 2 wt % to about 7 wt %, based on the combined weight of the phenolic resin, the latent acid, the catalyst, and the liquid medium.
