Type of resin used to produce plywood which has formaldehyde emissions higher than Phenol but lower than Urea. Melamine resin is manufactured by mixing urea with formaldehyde under heat and pressure. The substances begins to polymerize and are forced into a mold which create the desired shape. The materials finish polymerizing and create a finished product, melamine resin. Melamine-formaldehyde resin is similar to urea-formaldehyde resin in its processing and applications, but melamine resins are more moisture-resistant, harder, and stronger. Melamine moldings are glossy and one of the hardest plastics, and they retain a dust-free surface. However, their use in coatings is decreasing because of restrictions on the emission of formaldehyde, a major component of these coatings.
