摘要:
An emulsifier system comprising a) a salt of a sulfuric monoester of a C9-C15 alcohol or of an alkoxylated C9-C15 alcohol, and b) an alkoxylated C8-C16 alcohol, and the use of this emulsifier system for preparing aqueous polymer dispersions.
摘要:
Aqueous polymer dispersions contain, as a dispersant, a mixture of an ethylene oxide/propylene oxide copolymer, an ethoxylated alkylphenol and/or an ethoxylated fatty alcohol, an ethoxylated polysaccharide and, if required, as a further component, sulfuric acid half-esterified with an ethoxylated alkylphenol and/or an ethoxylated fatty alcohol.
摘要:
Binders for non-tacky, non-soiling, flexible coatings based on aqueous copolymer dispersions which contain zinc-amine complexes essentially consist of(A) from 99 to 90% by weight of a (meth)acrylate copolymer dispersion whose polymer has a glass transition temperature of from -40.degree. to -1.degree. C. and(B) from 1 to 10% by weight of a water-soluble zinc-amine complex salt of a polymeric carboxylic acid,the percentages by weight being based on the total amount of polymer.
摘要:
An aqueous polymer dispersion whose polymer is composed of vinyl-aromatic structures and conjugated dienes, and which has a reduced content of alkali metal ions, is used for producing water-vapor barriers; the invention also relates to the aqueous, low alkali metal polymer dispersion itself.

摘要:
The invention relates to a process for applying at least two chemically different, flowable media, particularly solutions of polymers, dispersions or combinations thereof as adhesives, coating materials or coatings. By means of a multiple cascade die 1 at least two chemically different, flowable media 30, 32 are applied to web-form substrates 20; 40, 41 continuously in one operation. The total amount within a multilayer application 51 is between 2 g per m2 to 200 g per m2. The ratio of the individual layers 31, 33 within the multilayer application 51 to one another is between 0.1 to 100.
