Seal coated devices

An activatable material coated device comprising:

• a) a device for fastening, baffling, sealing, or reinforcing;
• b) an activatable material, comprising:
• i) at least about 5.5% or greater of a blowing agent, a blowing agent accelerator, or both;
• ii) a curing agent;
• iii) one or more fillers or reinforcing components;
• and
• iv) one or more components comprising an acetate, a methacrylate, or a combination thereof;
• wherein the activatable material is dry to the touch prior to activation and located into direct contact with the device for fastening, baffling, sealing, or reinforcing prior to activation and is milled into an initial particulate size of at least 10 microns and at most 500 microns;
• wherein the activatable material is a frozen material prior to being milled;
• wherein the activatable material is adapted to be activated to expand to a thickness of from about 1 mm to about 10 mm greater than an initial thickness and adhere at temperatures of at least 180° C.;
• 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, so that the particulate activatable material softens and adheres to the device.
