Wood Composite Release Agents

Benefits of McLube Platen Sealers and Mat Coatings include reduced buildup of binder resins, high temperature tolerance to reduce browning, and reduced cost per meter2 of board.

About These Products

McLube’s line of wood composite release systems include semi-permanent platen sealers as well as dilutable, non-staining release coatings for mats, screens, and cauls. Our platen sealers and mat coatings work in tandem to protect equipment and prevent buildup of even the most tenacious resins so you can run presses longer.

Formaldehyde Regulations and pMDIs

While formaldehyde is an essential ingredient of cellular metabolism in mammals, studies have linked prolonged inhalation of formaldehyde gases to cancer. Engineered wood composites have been found to emit potentially harmful amounts of formaldehyde gas in two ways: unreacted free formaldehyde and chemical decomposition of resin adhesives. When exorbitant amounts of formaldehyde are added to a process, the excess will not have any additive to bond with and may seep from the wood product over time. Cheap urea-formaldehyde (UF) adhesives are largely responsible for degraded resin emissions. Moisture degrades the weak UF molecules, resulting in potentially harmful formaldehyde emissions. McLube® offers release agents and platen sealers designed for those manufacturers who use reduced-formaldehyde UF and melamine-formaldehyde adhesives.

Many oriented strand board (SB) and plywood manufacturers use phenol-formaldehyde (PF) because phenol is a much more effective additive. Phenol forms a water-resistant bond with formaldehyde that will not degrade in moist environments. PF resins have not been found to pose significant health risks due to formaldehyde emissions. While PF is an excellent adhesive, the engineered wood industry has started to shift toward polyurethane binders like pMDI to achieve even greater water-resistance, strength, and process efficiency. pMDIs are also used extensively in the production of rigid polyurethane foams and insulators for refrigeration.

pMDIs outperform other resin adhesives, but they are notoriously difficult to release and cause buildup on tooling surfaces. McLube® has developed a full line of release agents and platen sealers for pMDI adhesives based on decades of experience working with castable urethane and polyurethane foam manufacturers. Our release agents for pMDI will reliably release these tenacious adhesives and dramatically reduce buildup on platens and other wood press substrates.
