Abstract
A method of applying a protective film to a construction panel comprising: (a) selectively applying an adhesive composition to a peripheral region of a surface of the construction panel; and/or selectively applying an adhesive composition to a peripheral region of a surface of the protective film; and (b) applying a protective film to the surface of the construction panel to bond the protective film to the construction panel. A construction panel comprising a protective film layer on a surface of the panel and a peripheral adhesive composition layer located between said surface of the panel and the protective film layer, wherein the peripheral adhesive composition layer extends from an edge of the panel and across from about 0.1% to about 25% of the width of the surface.
Claims17
A method of applying a protective film to a construction panel, the method comprising:
- (a) selectively applying a first adhesive composition to a peripheral region of a surface of the construction panel at a coat weight of from 15 to 25 grams per square metre;
- (b) applying the protective film to the surface of the construction panel and bonding the protective film to the peripheral region of the surface of the construction panel by applying a pressure of from 400 kPa to 500 kPa to the peripheral region;
- wherein:
- a second adhesive composition is applied to the entire surface of the construction panel at a coat weight of from 30 grams to 60 grams per square metre prior to the step of selectively applying the first adhesive composition to the peripheral region of a surface of the construction panel;
- and
- the peripheral region extends from a position inset from the edge of the construction panel by a distance of from 0.5% to 2.5% of the width of the surface of the construction panel and across from 0.5% to 2% of the width of the surface of the construction panel.
