摘要

Coating procedure in several stagesIn which a pre coated substrate optionally apply a coat of primer and then a layer of an aqueous Composition of coating product,(a) which contains at least an oligomeric or polymeric compound and (TO) with at least two hydroxyl groups,(b) at least an oligomeric or polymeric compound and (b) with at least two groups of alquiliden - 1.3 - dioxolan - 2 - ona, and (d) at least one Catalyst for Crosslinking.Characterized in that the compound (b) containing at least two groups of alquiliden - 1.3 - dioxolan - 2 - one of the formula (i) * * * * in the formula which represents the Union of the backbone of the polymer and R1.R2, independently represent Hydrogen, alkyl, alkoxy of C1 - C6, c1-c4 alkyl of C1 - C4, C5 and C6 cycloalkyl alkyl or phenyl, phenyl - C1 - C4; R3 represents Hydrogen,Alkoxy alkyl of C1 - C6 C1 - C4 - c1-c4 alkyl, cycloalkyl of c5-c6 or phenyl, phenyl alkyl of C1 - C4In which case mainly R3 represents Hydrogen; a represents a Chemical Bond or alcanodiilo of C1 - C4In which case mainly represents alcanodiilo of C1 - C4; X represents o or nr7; Z represents a Chemical Bond, PO2, SO2 or OR = C,Where z represents primarily c = or ; and represents a Chemical Bond, chch3 CH2 or, in which case and mainly represents a Chemical Bond; R7, IF present,Represents alkyl of C1 - C6.
