DECORATIVE SURFACES Types and Inspection

DECORATIVE FOILS

Decorative foils are an intermediate-range paperbased overlay and are also called impregnated papers. They are generally pre-impregnated with a blend of melamine, acrylic and urea resins during the paper-manufacturing process or post-impregnated after the paper is fully cured. Decorative foils weigh between 40 and 200 grams/ m2 untreated. During the impregnation process, the cellulose papers typically gain between 20 and 50 percent of their base weight. Those between 100 and 200 grams are dubbed specialty papers and are more likely than lighter-weight varieties to be used for exposed decorative surfaces.

DECORATIVE PAPERS – LIGHT BASIS WEIGHT PAPERS

Decorative papers, also called light basis weight papers range in weight from 23 to 50 grams/m2. The decorative paper may contain acrylic, polyester or other resins added during the paper making process to improve the internal bond strength. The paper is then printed and top coated with polyurethane, urea, polyester, acrylic or melamine or a combination thereof for increased durability and performance for decorative use.

HIGH PRESSURE LAMINATES FOR DECORATIVE SURFACES

High Pressure Laminates (HPL) is the direct descendent of the original plastic laminate. It is considered to be one of the most durable decorative surface materials and is available with special performance properties including chemical, fire, and wear resistance. Special grades of high pressure laminates can be post formed around curved edges by application of heat and restraint.

THERMALLY FUSED LAMINATE (TFL) PANELS FOR DECORATIVE SURFACES

Thermally fused laminate (TFL) Panels, once known as thermally fused melamine or TFM, is made by fusing a resin-impregnated sheet of décor paper directly to a substrate. Heat and pressure activate the resin in the saturated TFL panel sheet, creating a cross-linked bond with the substrate. This effectively seals the substrate. Particleboard and MDF are ideal substrates for TFL because they are consistent, uniform in strength and free of defects.
