Abstract:
The invention relates to prepregs and composite components produced therefrom (mouldings), obtainable by the use of powdery reactive polyurethane compositions.
Abstract:
The invention relates to low monomer 1:1 monoadducts of reactive olefinic compounds and diisocyanates, to the production and to the use thereof.
Abstract:
The present invention relates to the use of alkoxysilane components in the presence of acid-generating photoinitiators in radiation-curable, free-radically crosslinkable formulations which in the cured state offer a particular degree of corrosion control for metallic substrates.
Abstract:
The present invention relates to novel formulations which are thermally curable and curable by actinic radiation, known as dual-cure formulations. The present invention also relates to the use, for the production of pigmented and pigment-free coating materials, or else for adhesives and sealants, of the novel formulations that are curable thermally and curable by actinic radiation.
Abstract:
The invention relates to silica-containing radiation-curable formulations which in the cured state offer a particular degree of corrosion control for metallic substrates.
Abstract:
Low-temperature-curable polyurethane compositions with uretdione groups, containing polymers based on polyols that carry secondary OH groups.
Abstract:
A radiation curable powder coating composition, comprising I.) a binder comprising A) 60-90% by weight of at least one amorphous urethane acrylate; and B) 10-40% by weight of at least one crystalline urethane acrylate; wherein a Tg of a mixture of A) and B) is at least 35° C.; and II.) an auxiliary and an additive, excluding an UV initiator, crosslinks to yield a lightfast and weather-stable film.
Abstract:
The invention provides polyisocyanates containing isocyanate groups from 1,4-diisocyanato-2,2,6-trimethylcyclohexane, having a trimer fraction of more than 80% by weight and an NCO content of at least 19.3%.
Abstract:
Solid polyurethane hardeners (curing agents) having triazine groups, are prepared by reacting polyaddition compounds with a second compound having a >C═N— group. The polyaddition compounds are prepared by reacting a uretdione-functional polyisocyanate with a hydroxy-functional chain extender.
