Prolam says its hot-melt polyurethane reactive P·u·R undercoating for the underside of laminated trailer floors is designed for superior moisture resistance, eliminating the challenges of traditional water-based paint coatings.

In climates with extreme weather conditions, water-based paint systems may break down when subjected to intense water spray and road debris. Specific areas such as trailer wheel locations are prone to degradation, according to Prolam; once water-based paint breaks down, the wood absorbs moisture, causing warping, swelling and deterioration of glue bonds.

P·u·R surpasses water-based coatings in industry standardized tests for elongation, abrasion, adhesion and water absorption, the company says, and it can be applied to the underside of laminated trailer floors in several possible configurations. For more information, go to
