摘要： Solvent-free hot melt compositions for use as sealants, adhesives, caulking compounds or the like are produced by intimately blending elastomeric polymers with tackifying resins and plasticizers to obtain products having a hardness at room temperature of at least about 5 on the Shore A Durometer scale while being sufficiently soft at temperatures of about 150.degree. F. or higher to permit them to be easily extruded or otherwise applied. Adhesion promoters, lubricants, fillers and the like are preferably added to the composition to improve the properties thereof. The products are characterized by their stability over a wide range of temperatures, their resistance to oxidation and weathering, and their low moisture vapor transmission properties.

摘要： A preformed or prefabricated hot melt sealant strip of essentially any desired length and with any desired cross-sectional configuration is formed by hot extrusion, cooled, and coiled or spooled and may be subsequently used, for example, as a sealing means in the assembly of multiglazed windows, to seal and set automobile windshields and the like. The preferred cross-section is U-shaped if the sealant strip is to be utilized for multiglazed windows but the strip may have a T, E, L shape, or the like, depending on the intended end use. Any hot melt adhesive or sealant composition is suitable as long as it is not too tacky in the cooled state. Some tackiness is acceptable but it requires the use of an abherent or release liner if the strip is to be packaged in such a manner that it is in contact with itself. The sealant strip may then be placed about a dessicant filled spacer element and located between two panes of glass. The sealant may then be activated by subjection to thermal energy to seal the unit.
