ABSTRACT:
The present invention relates to resin mixtures which are fluid at temperatures up to 100.degree. C. and which crosslink either at elevated temperature or under the influence of moisture. Thermal crosslinking takes place at temperatures of 100.degree. C. and up, preferably at about 120.degree. C. The mixtures contain one or more mutually compatible polymers containing hydroxyl groups, in which at least 5% and not more than 90% of the hydroxyl groups are replaced by alkoxysilyl groups. The introduction of the alkoxysilyl groups is accomplished by the reaction of a diisocyanate with a hydroxyl group on the polymer, on the one hand, and with an aminosilane or mercaptosilane ester on the other. On the basis of their fluid-to-viscous consistency at room temperature or moderately elevated temperature, the resins can be applied in a thin coating and easily crosslinked in situ.
