摘要:
This invention relates to novel suspensions containing (a) 30 to 95 wt. % of water, (b) 70 to 5 wt. % of at least one silane or siloxane having at least two groups corresponding to formula (I) —(CH2)mSiRnX3-n (I) wherein R denotes C1-C18 alkyl and/or C6-C20 aryl, X denotes OH, C1-C4 alkoxy, C6-C20 aryloxy, C1-C6 acyloxy and/or hydrogen, m is 1 to 6, and n is 0 to 2, (c) 0.1 to 30 wt. % of at least one emulsifier, and (d) 0 to 20 wt. % of one or more additives and/or auxiliary substances, with the proviso that the sum of components (a) to (d) totals 100 wt. %. The present invention further relates to the preparation and use of such suspensions.
摘要:
Process for preparing non-aqueous dispersions, wherein a liquid prepolymer is emulsified in a non-aqueous liquid, the droplet size of the emulsion is adjusted to 0.1 to 30 .mu.m and the droplet size distribution U.sub.90 is adjusted to less than 2 by means of a jet disperser, and the droplets are cured by a chemical reaction.

The present invention relates to innovative polyisocyanate mixtures comprising cycloaliphatic structural elements and containing exclusively linear-aliphatically attached free isocyanate groups, to a process for preparing them and to their use as a starting component in the production of polyurethane plastics, more particularly as a crosslinker component in polyurethane coating materials and coatings.
摘要:
The present invention relates to blocked polyisocyanates containing at least one radiation-curable groups and at least one structural unit of the formula (II) wherein R1, R2 and R3 independently of one another are hydrogen or a C1-C4 alkyl radical or a cycloalkyl radical, R4 is a C1-C4 alkyl, C6-C10 cycloalkyl or C7-C14 aralkyl radical and x is an integer from 1 to 5. The present invention also relates to a process for preparing these blocked polyisocyanates and to dual-cure coating, adhesive or sealant compositions containing these polyisocyanates.

摘要:
A process for the preparation of dual-cure hardeners, coating systems which contain these hardeners, and the use of these coating systems, as well as substrates coated with these coating agents. The dual-cure hardeners are prepared by reacting at least one diisocyanate or polyisocyanate A with the product B of the reaction of B1 acrylic acid, methacrylic acid and/or dimeric acrylic acid with B2 glycidyl methacrylate and/or glycidyl acrylate, wherein B contains less than 0.2 wt. % of epoxide groups
