Abstract
The present invention provides a method for making a medium density fiberboard having a surface layer that is substantially similar to the subsurface layer. In one embodiment the method includes the step of applying a sealer composition having at least one of a release agent, bonding agent, or plasticizer to a fibermat and consolidating the fibermat.
Claims31
A method of making a medium density fiberboard, comprising:
- providing a fibermat having one or more layers of a mixture of wood fibers and a binder;
- providing a sealer composition having at least one of a release agent, bonding agent, or plasticizer ingredient;
- applying the sealer composition to at least one major surface of the fibermat;
- and then
- consolidating the fibermat, thereby forming a medium density fiberboard with an unsanded surface layer having a cohesive strength that is substantially similar to or greater than the cohesive strength of a subsurface layer of the fiberboard.
A medium density fiberboard having an unsanded surface layer with a density that is substantially similar to the density of the subsurface layer of the fiberboard.
A method of making a medium density fiberboard, comprising:
- providing a fibermat having one or more layers of a mixture of wood fibers and a binder;
- providing a sealer composition having at least one of a release agent, bonding agent, or plasticizer ingredient;
- applying the sealer composition to at least one major surface of the fibermat;
- consolidating the fibermat, thereby forming a medium density fiberboard with a surface layer that substantially accepts paint, lamination or gluing, without being sanded.
A method of making a medium density fiberboard, comprising:
- providing a fibermat having one or more layers of a mixture of wood fibers and a binder;
- providing a scaler composition having at least one of a release agent, bonding agent, or plasticizer ingredient;
- applying the sealer composition to at least one major surface of the fibermat;
- and then
- consolidating the fibermat, thereby forming a medium density fiberboard without a deficient surface layer.

- providing a sealer composition having at least one of a release agent, bonding agent, or plasticizer ingredient;
- applying the sealer composition to at least one major surface of the fibermat;
- and then,
- consolidating the fibermat, thereby forming a medium density fiberboard with an unsanded surface layer having a density that is substantially similar to or greater than the density of a subsurface layer of the fiberboard.
