Abstract:
1. A liquid resin composition, comprising, based on the total weight of the liquid resin composition: (I) at least 30 wt % of a novolac resin having a glass transition temperature less than or equal to 60° C., wherein the novolac resin is obtained by reacting formaldehyde and phenol in the presence of an acid catalyst, and wherein the novolac resin contains less than 0.1% by weight of free formaldehyde; (II) at least 10 wt % of a reactive diluent, wherein the reactive diluent is a liquid at room temperature and comprises at least one functional group selected from the group consisting of a hydroxy, an aldehyde, an epoxy, an oxazolidine, and a lactone; and (III) from 20 wt % to 40 wt % of a crosslinking agent, wherein the liquid resin composition has a viscosity of less than or equal to 7,000 mPa·s at room temperature.
