ABSTRACT:
New sealing adhesive bed compositions for glazing are form retaining and comprise elastomeric material initially mixed with plasticizers of low volatility and finely divided solids which either are of fibrous form or produce thixotropic mixtures with the plasticizers. A ratio range of from 3/4 to 21/2 parts non-volatile plasticizers to one part elastomeric material, and from 0.3 to 21/2 parts such finely divided solids to one part elastomeric material is present. Other kinds of finely divided solids and other ingredients may be present. The glazing strand is formed by extrusion, and the formed strand is not cured after extrusion. The tapes permanently deform under pressure when the glass is installed, have low spring back and exhibit little or no creep or cold flow in service.
