Resins are solvent extracted yielding from an alcohol-soluble substance that is less dense, more sticky and liquid-like, called a Resinoid. The absorption of water by resins is a phenomenon of considerable importance since it is accompanied by dimensional changes. The further undesirable effect of absorbed water in acrylic resins is to reduce the tensile strength of the material. For more details, visit http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2635902/.
