How should release agents be applied in a wood pressing operation?

Application of release agents depends on the type of pressing operation and the specific parameters of the mill. For multi-opening “daylight” presses, the release agent is typically sprayed onto the wood furnish directly or, when necessary, onto transfer belts or caul screens which transfer the release agent onto the bottom of the wood mat or billet.

For continuous presses, the release agent is most typically sprayed directly onto the pressing belt just prior to the inlet of the press. In some cases a transfer roller is used to apply the release agent to the belt instead of a sprayer.

Finally, internal release agents are sometimes used in the process. Internal release agents are mixed with the wood furnish, usually just before or after the binder is incorporated.
