摘要:
A heated substrate is dipped into a fluidized bed containing particles of polymer to coat the substrate. The coating can subsequently be leveled (and cured if thermosetting) by heating the coated substrate above the melting point of the polymer. The process can be employed to provide desirable properties such as corrosion resistance and aesthetic qualities to the substrate, and to apply very thin coatings.

This invention provides moisture stable tuftstring carpet assemblies. The pile surface structure comprises a moisture stable backing substrate, a plurality of elongated pile articles each comprising an elongated, moisture stable support strand having bonded thereto a plurality of "U" shaped bundles of multifilament yarn. The pile articles are bonded to the backing substrate. Different backing substrates and support strands may be used.
摘要:
The present invention relates to methods for bonding articles made of polymers, and in particular, fluoropolymers. According to a first embodiment of the present invention, the method comprises the steps of coating the surface of either one or both of the articles to be bonded with a third polymer so that one or both of the articles has a layer of the third polymer adhered thereto, and bringing the articles into contact with each other after the articles are coated in order to bond the articles together. According to a second embodiment, the method comprises the steps of placing a composite layer comprising either conductive or magnetic materials, or both, between the articles, bringing the articles and the composite layer into contact with each other and electromagnetically heating the composite layer to bond the articles together.
