Abstract
Described herein are methods for preparing multilayer composites comprising a fiberglass substrate encapsulated, at least in part, by a calendered film; along with products produced from same. The methods improve the efficiency of the manufacturing process and provide a product with improved performance characteristics.
Claims15
A method for preparing a multilayer composite comprising:
- providing a fiberglass substrate;
- applying a calendered film to a first major surface of the fiberglass substrate such that at least a portion of the fiberglass substrate remains exposed after the calendered film is applied to the first major surface of the fiberglass substrate;
- and
- applying a foamable resin to a second major surface of the fiberglass substrate,
- wherein at least a portion of the foamable resin layer is in contact with said calendered film layer.

A method for preparing a multilayer composite comprising:
- providing a fiberglass substrate;
- applying a calendered film to a first major surface of the fiberglass substrate such that at least a portion of the fiberglass substrate remains exposed after the calendered film is applied to the first major surface of the fiberglass substrate;
- applying a foamable resin to a second major surface of the fiberglass substrate;
- and
- further comprising the step of embossing the foamable resin layer and embossing the calendered film layer.
