Liquid Phenolic Resole Resin in Alcohol Product description Phenolic resins are synthetic polymers formed as condensation products of phenols and aldehydes. This step-growth polymerization reaction can be either acid- or base-catalyzed. In acid, the reaction forms novolac resins. These resins require a curing agent - often hexamethylenetetramine or hexa.They are not heat-sensitive. In alkaline solution, the polymerization reaction produces resole resins. These resins are
