Abstract
A contiguous surface film for a composite strip, such as a weatherseal is disclosed, wherein the surface film is formed of a colliquefied powder coating. The surface film can be located on a carrier, sealing or trim portion of the weatherseal, wherein the surface film can be colored, and selected to provide a desired surface characteristic such as reduced coefficient of friction.
Claims32
A composite strip, comprising:
- (a) a resilient body;
- and
- (b) a colliquefied powder coating forming a contiguous surface film on a portion of the resilient body, the surface film having a thickness less than 0.2 mm.
A composite strip, comprising:
- (a) a substrate having a first portion formed of a first material and a second portion formed of a different second material;
- and
- (b) a powder coating colliquefaction forming a contiguous surface layer bonded to the first portion and the second portion.
A weatherseal comprising a colliquefaction of a powder coating defining a contiguous surface film on a portion of the weatherseal.
A composite strip for sealing an interface between two confronting surfaces, the composite strip comprising;
- (a) a base;
- (b) a sealing portion for contacting one of the confronting surfaces;
- and
- (c) a colliquefication of a powder coating forming a contiguous surface film on one of the base and the sealing portion.
A method of forming a surface film on a portion of a weatherseal, comprising:
- (a) creating an electric potential between the portion of the weatherseal and powder coating;
- (b) exposing the powder coating to the electric potential to attach the powder coating to the portion of the weatherseal;
- and
- (c) melting the powder coating on the portion of the weatherseal to form a contiguous surface layer on the portion of the weatherseal.
The method of claim 28, further comprising employing a thermosetting material in the powder coating.
A method of forming a surface film on a weatherseal, comprising:
- (a) forming a resilient body about an electrically conductive member;
- (b) exposing the electrically conductive member to an electrical potential to form a surface charge on the resilient body;
- (c) exposing the surface charge on the resilient body to an oppositely charged powder coating to attract the powder coating to the resilient body;
- and
- (d) melting the powder coating on the resilient body to form a contiguous surface layer bonded to the body.
A method of forming a contiguous surface film on a weatherseal, comprising:
- (a) retaining a powder coating on the weatherseal;
- and
- (b) colliquefying the retained powder coating to form a contiguous surface film.
