Document Type and Number:
Japanese Patent JP2758622
Kind Code:
B2
Abstract:
The process is characterised in that a substrate is coated with a product obtained by reacting A) a prepolymer containing an average of 2 ketoxime-blocked NCO groups and having a mean molecular weight of from 500 to 15,000, based on an aromatic polyisocyanate, with B) a chain extender of the formula
H2N-R'-NH2
in which R' is an aliphatic radical,
in the presence of solvents at temperatures of >50 DEG C and at a ratio between the number of equivalents of blocked NCO groups and NH2 groups of 1.43 to 1.02, with from 40 to 90 % of the available amino groups being reacted, and the reaction is subsequently completed at temperatures of >120 DEG C with crosslinking.
