Prelam MDF Board – Exterior Grade
Advantages
-No risk of de-lamination
-Resistant to abrasion, household chemicals, steam, cigarette burns and cracking
-Can be used where the panel is exposed to high moisture and humidity
-Free from waves, air pockets or any other bonding defects
-Unlike pre-laminated particle board and plywood, the edges are smooth and hence it reduces the cost of finishing
-No additional cost in finishing the surface of panel
-Available in wide range of shades in pastel & wood grain
Applications
Furniture,Partition,Flooring & Ceiling,Wall paneling,Kitchen cabinets and shutters
