Beschreibung
Zusammenfassung:	Disclosed herein are coating compositions comprising a blocked polyol having a first hydroxyl group at position 1 carbon atom and a second hydroxyl group at position 2 or 3 carbon atom, wherein both the first and the second hydroxyl groups are blocked by a single hydrolyzable orthoformate group; and a polyisocyanate compound. Methods of producing and using said coating compositions are also disclosed. La présente invention concerne des compositions de revêtement comprenant un polyol séquencé comportant un premier groupe hydroxyle sur un atome de carbone en position 1 et un second groupe hydroxyle sur un atome de carbone en position 2 ou 3, le premier et le deuxième groupe hydroxyle étant séquencés par un seul groupe orthoformate hydrolysable; et un composé polyisocyanate. Cette invention concerne également des procédés de production et d'utilisation de ces compositions de revêtement.
