Abstract
The invention relates to a modified allophanate compound bearing acrylate functions, resulting from the reaction of a particular allophanate with an ester from the reaction between an acid selected from acrylic acid and methacrylic acid and at least one polyol that does not contain an oxylakylene or aa (poly)oxyalkylene group. The invention further relates to the use of said modified allophanate for preparing a hydrophobic cross-linkable coating composition by means of UV radiation.
