C. of 60 Pa.s,D. from 0 to 20% by weight of an organic solvent with an evaporation number of 0.
摘要:
A viscous cellulose substance containing paste which is characterized by containing an alkoxylated plasticizer and a ratio of solid to the organic solvent phase of .gtoreq.1 and which can be used to prepare a lacquer consisting at most of 25% of an organic solvent.
摘要:
Improved cellulose ester-polymer combinations contain a cellulose ester A and at least one polymerized monomer B of the following formula ##STR1## wherein the substituents have the meaning given in the description and wherein the particles of the combinations are essentially 0.1 to 10 mm in size.
摘要:
Improved cellulose ester dispersions in the aqueous phase contain dispersed particles which contain cellulose esters, a polymerized monomer A having a polymerizable double bond and a polymerized monomer B having at least two polymerizable double bonds.
摘要:
Water soluble, polymerizable binders suitable for surface coating contain co-condensed residues of at least two polyalkylene glycols with different molecular weights, an alkoxylated polyol, a polycarboxylic acid and an optionally substituted acrylic acid.
摘要:
Nitrocellulose moistened with alcohol, particularly for polyurethane lacquers, characterized in that a lower aliphatic tertiary alcohol is used as moistening agent.
摘要:
The present invention relates to polyester acrylate/urethane dispersions based on polyester acrylate prepolymers containing hydroxyl groups, obtainable by polyaddition of A. 40-90 wt. % of one or more polyester acrylate prepolymers containing hydroxyl groups and having an OH content of 40-120 mg of KOH/g and B. 0.1-20 wt. % of one or more mono- and/or difunctional compounds reactive towards isocyanate groups, which compounds contain groups which are cationic, artionic and/or have a dispersant action due to ether groups with C. 10-50 wt. % of one or more polyisocyanates D. 0.0-30 wt. % of polyols together with a subsequent reaction with E. 0.1-10 wt. % of one or more di- and/or polyamines.
摘要:
The invention relates to novel branched polyesters containing allyl groups, which polyesters are water-emulsifiable, and their use as raw materials for lacquers.
摘要:
The invention relates to free-flowing, quick-dissolving lacquer binder granules based on cellulose esters, more particularly cellulose nitrates, and to a process for their production.
摘要:
This invention relates to new water-emulsifiable polyester resins, a process for their production and their use as a lacquer row material. These lacquer binders are produced by the reaction of at least one prepolymer A which contains (meth)acryloyl groups and at least one unsaturated water-emulsifiable polyester B with at least one polyisocynate C.
