PROCESS FOR COATING HOT MELT ADHESIVES |
摘要 |
Hot melt adhesive masses are provided with a tackless surface by a process which comprises the steps of: a) extruding the hot melt adhesive through an appropriate die orifice; b) spraying the surface of the extruded adhesive with a molten film forming low molecular weight polymer or formulated polymeric material, the material being selected so that it will not appreciably detract from the properties of the adhesive composition when remelted therewith; c) heating the surface of the coated adhesive at a temperature and for a period of time sufficient to remelt the film forming polymer so as to form a continuous coating thereof yet insufficient to appreciably melt the adhesive; and d) cooling the thus coated adhesive mass to a temperature suitable for handling.
