摘要:
A process for the production of storage-stable epoxy prepregs is provided. In addition, composites produced from the prepregs based on epoxides and acids having groups reactive to free-radical polymerization is provided.
摘要:
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.
摘要:
The invention relates to silica-containing radiation-curable formulations which in the cured state offer a particular degree of corrosion control for metallic substrates.
摘要:
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.
