摘要:
The invention relates to a process for preparing free-flowing, pulverulent alkoxycarbonylaminotriazine from an alkanolic reaction mixture which is obtained in the preparation of alkoxycarbonylaminotriazines and comprises at least one alkoxycarbonylaminotriazine, at least one cyclic and/or acyclic carbonic ester, at least one C1-C13-alkanol which optionally comprises one or two oxygen atoms in the form of ether bonds and is optionally substituted by C1-C4-alkyl and/or hydroxyl, and also at least one alkali metal or alkaline earth metal alkoxide, with or without melamine and with or without catalyst, by atomizing and drying the reaction mixture in a spray drier.

A panel element is provided for arrangement on a water box of a front wall of a motor vehicle body, with a fastening edge for forming a fastening of the panel element arranged upstream of the water box in travelling direction of the motor vehicle and adjoining the water box and with at least one water-conducting depression for the controlled discharge of accumulating water.
摘要:
The invention relates to a printable precursor comprising an organometallic zinc complex which contains at least one ligand from the class of the oximates and is free from alkali metals and alkaline-earth metals, for electronic components and to a preparation process. The invention furthermore relates to corresponding printed electronic components, preferably field-effect transistors.
摘要:
A fastening device is provided for the releasable fastening of a panel element to the front wall structure of a motor vehicle body, with a brace, which on one end can be fastened with a fastening structure of the panel element and on the other end can be fastened with a fastening structure of the front wall structure. The brace is releasable and positively fastened to at least one of the fastening structures with at least one end section.
