Starch-based adhesives used in any application that requires water resistance must contain additives that resist water. Commonly used additives of this type are urea-formaldehyde, melamine-formaldehyde, and resorcinol-formaldehyde precondensates, poly(vinyl alco­hol), and poly(vinyl acetate). The greatest water resistance is imparted by the formalde­hyde-based precondensates; poly(vinyl alcohol) and poly(vinyl acetate) are used for adhesives that are resistant to cold water but can dissolve in hot water.
