Abstract

Self-sealing fasteners and associated building panels, systems, and methods are provided. In one aspect, a fastener includes an elongated fastener body with an external surface extending between the first end and the second end, and a coating material disposed on at least a portion the external surface. In another aspect, a fastener includes an elongated fastener body with an external surface extending between the first end and the second end, and a polymer annulus surrounding at least a portion of the external surface of the of the elongated fastener body at or adjacent the head of the fastener.

First claim

What is claimed is:

1. A building panel, comprising:
a panel core having a first surface and a second opposed surface;
a mat associated with the first surface of the panel core, and forming an external surface of the panel; and
at least one dot of coating material disposed on the external surface of the panel,
wherein the coating material displays a viscosity of less than 1 Pa·s, measured at a shear rate of 1000 Hz and at a temperature of 150° F.

2. The building panel of claim 1 , wherein the coating material comprises a pressure-sensitive hot melt.

3. The building panel of claim 2 , wherein the pressure-sensitive hot melt comprises a polymer selected from a group consisting of styrene block copolymers, styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylene/butylene-styrene, styrene-ethylene/propylene adhesives, ethylene-vinyl acetate, ethylene-acrylate copolymers, polyolefins, polybutene-1, amorphous polyolefin, polyamides, polyesters, polyurethanes, including reactive or thermoplastic polyurethanes, polycaprolactone, polycarbonates, fluoropolymers, silicone rubbers, and thermoplastic elastomers.

4. The building panel of claim 2 , wherein the pressure-sensitive hot melt has a melt temperature of at least 330° F.

5. The building panel of claim 1 , wherein each dot contains the coating material in an amount of from about 0.05 g to about 0.5 g.

6. The building panel of claim 1 , wherein the building panel comprises a grid of a plurality of the dots of coating material disposed on the external surface of the panel.

7. The building panel of claim 1 , wherein the building panel is a gypsum panel in which the panel core comprises gypsum and the mat is a fiberglass mat, wherein gypsum of the gypsum core penetrates a remaining portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated.

8. The building panel of claim 6 , wherein the grid of the plurality of the dots of coating material comprises columns of dots equidistantly spaced at a standard stud spacing, such that the dots align with studs having the standard stud spacing.

9. The building panel of claim 8 , wherein the standard stud spacing is 16 inches or 24 inches.

10. The building panel of claim 1 , wherein the building panel comprises from 0.0001 lb/ft 2 to 0.0025 lb/ft 2 , of coating material.

11. A building panel, comprising:
a panel core having a first surface and a second opposed surface;
a mat associated with the first surface of the panel core, and forming an external surface of the panel; and
a plurality of dots of a coating material disposed in a grid on the external surface of the panel, wherein the grid comprises columns of dots equidistantly spaced at a standard stud spacing,
wherein the coating material displays a viscosity of less than 1 Pas, measured at a shear rate of 1000 Hz and at a temperature of 150° F.

12. The building panel of claim 11 , wherein the coating material comprises a pressure-sensitive hot melt.

13. The building panel of claim 12 , wherein the pressure-sensitive hot melt comprises a polymer selected from a group consisting of styrene block copolymers, styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylene/butylene-styrene, styrene-ethylene/propylene adhesives, ethylene-vinyl acetate, ethylene-acrylate copolymers, polyolefins, polybutene-1, amorphous polyolefin, polyamides, polyesters, polyurethanes, including reactive or thermoplastic polyurethanes, polycaprolactone, polycarbonates, fluoropolymers, silicone rubbers, and thermoplastic elastomers.

14. The building panel of claim 12 , wherein the pressure-sensitive hot melt has a melt temperature of at least 330° F.

15. The building panel of claim 11 , wherein each dot of the plurality of dots contains the coating material in an amount of from about 0.05 g to about 0.5 g.

16. The building panel of claim 11 , wherein the building panel is a gypsum panel in which the panel core comprises gypsum and the mat is a fiberglass mat, wherein gypsum of the gypsum core penetrates a remaining portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated.

17. The building panel of claim 11 , wherein the standard stud spacing is 16 inches or 24 inches.

18. The building panel of claim 11 , wherein the building panel comprises from 0.0001 lb/ft 2 to 0.0025 lb/ft 2 , of coating material.
