Advantages:

  1. The cover of the least expensive coating that is used in inexpensive furniture and appliances
  2. Paper coating against abrasion, scratches and other mechanical strength, and resistance to heat and humidity is less than crowns melamine laminate.

Technical Specifications:

Paper coated with a layer of decorative paper usually basis weight 140.40 grams per square meter (before impregnation) impregnated with resins, melamine formaldehyde and dried, was formed. This coating is then impregnated basis weight of up to 300 grams per square meter reach. This coating for sheets of various sizes that are mostly rolls and simple forms, patterned, matte or gloss are produced. Paper crowns using glue and presses categorical or continuous (roll, rollers) attach on the board. Adhesives used are urea formaldehyde, polyvinyl acetate, PVA and so on.
Coated paper is used in addition to the coverage in the papers MDF, to create a simple edge tape and the adhesive and coating profiles and folded edges of the tool is used.
Used for coating MDF with wheels (with size 100 Grit) are grinding. Surface must be clean and without dust and roughness. The size, MDF for the coating work is important, because if not the same grading in plantations with high-speed coating makes the difference is the quality of adhesion of coating to boards.
