Abstract
An activatable material coated device comprising a device and an activatable material, comprising at least about 5.5% or greater blowing agent, blowing agent accelerator or both. The activatable material is milled into a particulate size of from about 500 microns to about 10000 microns and the device is heated to a temperature of at least about 30° C. but below an activation temperature of the activatable material and contacted with the particulate of the activatable material, adhering the activatable material to the device.
Claims20
An activatable material coated device comprising:
- a. a fastening device selected from a bolt, a nut, a weld nut, a screw, a clamp, a flange, a grommet, a rivet, a retaining pin, a peg, a nail or a tree-fastener;
- b. an activatable material, comprising:
- i. at least about 5.5% or greater blowing agent, blowing agent accelerator or both;
- ii. a curing agent;
- and
- iii. one or more fillers or reinforcing components;
- wherein the activatable material is milled into a particulate size of at least 5000 microns and at most 100,000 microns;
- and
- wherein the device is heated to a temperature of at least about 30° C. but below an activation temperature of the activatable material and contacted with the particulate of the activatable material, adhering the activatable material to the device, so that the device is coated with a layer of the activatable material prior to activation of the activatable material.
A method for producing an activatable material coated device comprising:
- a. providing a fastening device selected from a bolt, a nut, a weld nut, a screw, a clamp, a flange, a grommet, a rivet, a retaining pin, a peg, a nail or a tree-fastener;
- b. pelletizing an activatable material;
- c. optionally freezing the activatable material;
- d. milling the activatable material to a particulate having an average size of at least 5000 microns and at most 100,000 microns;
- e. heating the device to a temperature of at least about 30° C. but below an activation temperature of the activatable material;
- and
- f. contacting the device with the milled activatable material thereby adhering the activatable material to the device;
- wherein the activatable material comprises at least about 5.5% by weight or greater blowing agent, blowing agent accelerator or both.
