CONSTRUCTION BOARDS HAVING A PRESSURE-SENSITIVE ADHESIVE LAYER
A construction board comprising a foam layer, an pressure-sensitive adhesive layer that is at least partially cured, and a release liner.
1 - 17 . (canceled)
18 . A method of forming a construction board composite, the method comprising:
(i) providing a first facer having first and second planar surfaces, where a pressure-sensitive adhesive layer is disposed on said first surface of said first facer, and a release member is removably attached to said adhesive layer;
(ii) applying a developing foam to the second surface of said first facer;
(iii) providing a second facer; and
(iv) applying the second facer to said developing foam.
19 . The method of claim 18 , where said first facer is a glass mat.
20 . The method of claim 19 , where said first facer is a coated glass fiber mat.
21 . The method of claim 19 , where said glass fiber mat has a thickness of from about 0.015 to about 0.03 inch.
22 . The method of claim 18 , where said second facer is a glass mat.
23 . The method of claim 22 , where said second facer is a coated glass fiber mat.
24 . The method of claim 23 , where said glass fiber mat has a thickness of from about 0.015 to about 0.03 inch.
25 . The method of claim 18 , where said developing foam is a polyurethane foam.
26 . The method of claim 18 , where the pressure-sensitive adhesive layer has a thickness of from about 2 to about 15 mil.
27 . The method of claim 18 , where the pressure-sensitive adhesive layer is a polyacrylate.
28 . The method of claim 18 , where said applying a second facer forms a sandwiched structure, and further comprising the step of heating the sandwiched structure.
