Abstract
Materials are bonded together by means of an adhesive which comprises a blend of a poly(arylene sulfide) and polytetrafluoroethylene. Coatings of the adhesive can be applied to each of the materials to be bonded and partially cured. The coated surfaces can then be placed in contact with one another and curing of the adhesive completed.
Claims7
The method of bonding a first material to a second material which comprises applying a coating of a mixture of a poly(arylene sulfide) and polytetrafluoroethylene to each of the materials, heating each coating to effect a partial cure of the poly(arylene sulfide) before the two materials are placed adjacent one another, and thereafter placing the two materials adjacent one another so that the thus partially cured coatings of each material contact one another, and heating the mixture to effect a cure of the poly(arylene sulfide) and thereby bond the two materials together.
