BRUKSFAERDIGA LIMBEHAOLLARE.

摘要

The ready-to-use adhesive packs are characterised by the following features: a) adhesives based on thickened creamy or pasty emulsion polymers which are readily spreadable but do not flow without the application of pressure and which contain a homopolymer and/or copolymer of adhesive character stabilised with protective colloids or thickeners in the aqueous phase as a disperse solid are b) present in containers which can be grasped with one hand and have a discharge opening for the adhesive and a means for controlled dispensing of adhesive wherein c) there is provided a means which reduces the adhesive-filled interior of the container at a rate commensurate with the rate of discharge of adhesive in such a way that the adhesive material remaining behind in the container is always void-free and safe from air return. The preferred adhesives are stabilised aqueous emulsion polymers having viscosities (Brookfield RTV, 20 DEG C and 20 rpm) of at least 15,000 mPas, in particular within the range from 50,000 to 500,000 mPas, and they contain as thickeners of virtually unlimited storage life polyethylene glycol or copolyethers of ethylene oxide and propylene oxide having an average molecular weight of at least 3,000.
