摘要:
Low molecular mass adduct compositions of isocyanatoalkyltrialkoxysilanes and aliphatic alkyl-branched diols or polyols are provided. The adduct compositions are liquid at temperatures of greater than 0° C. Coating compositions which provide scratch resistant clearcoat coatings upon curing are also provided.
摘要:
The invention relates to plastisols which even without the addition of adhesion promoters exhibit high adhesion to metallic and cathodically deposition-coated substrates.
摘要:
The invention relates to an apparatus for extracorporeal blood treatment having a dialyzer which is divided into a first and a second chamber 29, 30 by means of a semipermeable membrane wherein the first chamber 29 is arranged in a dialysate path and the second chamber 30 can be connected to a patient's blood circulation by means of a blood supply line 32 and a blood discharge line 31, an inlet 20 for fresh dialysate, an outlet 36 for spent dialysate, a measuring device 37, wherein the measuring device 37 has at least one radiation source 1 for substantially monochromatic electromagnetic radiation. Thereby the measuring device 37 for determination of a luminescence of the spent dialysate flowing through the outlet 36 has at least one detector system (5) for detecting the intensity of the electromagnetic radiation generated by luminescence.
摘要:
The invention relates to compounds made of (cyclo)aliphatic diisocyanates, produced according to a multi-stage method (phosgene-free production), which comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleavage of the latter into the (cyclo)alkylene diisocyanates and alcohol (urea route), and aromatic acid halides, and to the use thereof.
摘要:
A composite is produced by I. producing a reactive composition containing A) at least one organic diisocyanate and/or polyisocyanate; B) at least one compound having at least one functional group reactive toward NCO groups, wherein the ratio of NCO groups of A) and the functional groups of B) varies from 1:2 to 2:1; C) a catalyst mixture containing C1) at least one titanium compound and C2) at least one bismuth compound in a C1:C2 ratio of 100:1 to 1:100; and D) optionally, an additive; wherein the amounts of A)-D) add up to 100% by weight, II. directly impregnating a fibrous carrier with the composition from I., to obtain an impregnated fibrous carrier, III. shaping the impregnated fibrous carrier to give a molding, and IV. curing the reactive composition I.

The invention relates to plastisols which even without the addition of adhesion promoters exhibit high adhesion to metallic and cathodically deposition-coated substrates.
摘要:
Detection device for quantitative detection of predetermined molecules, in particular medium size protein molecules, in a sample liquid with a light source for emitting measurement radiation, a section for irradiating the sample liquid and a light detector for measuring the detection radiation exiting the section for irradiating the sample liquid, as well as an analysis stage located downstream of the light detector for analyzing the detector signal, wherein the light source is designed such that the measurement radiation has a spectral range exciting the intrinsic fluorescence of a molecule to be determined, and the light detector is designed such that at least one spectral range of the detection radiation is measured, in which the molecule emits intrinsic fluorescence radiation.
摘要:
The invention relates to NCO-functional prepolymers prepared from dicyclohexylmethane diisocyanate (H12MDI hereinafter) and polyether polyols, with a reduced tendency to crystallization, a fraction of the H12MDI being blended with further monomeric isophorone diisocyanate (IPDI hereinafter), so making it possible to reduce or prevent entirely the tendency to crystallization, and also to the preparation and use.
