Patent number: 7790236Abstract: The invention relates to a high gloss car wash-resistant coating composition comprising an epoxy-functional binder and a cross-linker reactive with the epoxy groups of the binder and a method to prepare such a car wash-resistant coating. The invention further relates to the use of said coating composition, as a pigment-free top coat or a clear coat, in the finishing and refinishing of articles, for example motorcycles, cars, trains, buses, trucks, and aeroplanes. The coating composition after curing forms a coating having an initial gloss of at least 81 GU and a loss of gloss (LoG) of less than 0.25, the loss of gloss being determined by the formula (I) LoG =(1?e(A/X)/(1+eK)+(1?eD*?Tg)??(I) wherein K=B*(Tgonset?C) In formula I A=?8.03, B=?0.21, C=328 and D=?0.00304.Type: GrantFiled: October 25, 2005Date of Patent: September 7, 2010Assignee: Nuplex Resins B.V.Inventors: Cornelis Adrianus Maria Vijverberg, Martin Bosma, Johannes Wilhelmus Maria Schellekens, Freddy Gerhard Hendrikus Van Wijk

Patent number: 7728075Abstract: The invention relates to a high gloss car wash-resistant coating composition comprising a hydroxyl-functional binder and a cross-linker reactive with the hydroxyl groups of the binder and a method to prepare such a car wash-resistant coating. The invention further relates to the use of said coating composition, as a pigment-free top coat or a clear coat, in the finishing and refinishing of articles, for example motorcycles, cars, trains, buses, trucks, and aeroplanes. The coating composition after curing forms a coating having an initial gloss of at least 81 GU and a loss of gloss (LoG) of less than 0.18, the loss of gloss being determined by the formula (I): LoG=A+B·E?·(X)?1·10(C·?Tg)+D·(E?)?0.5; wherein A=0.0132, B=1.0197, C=0.0113, and D=0.0566, E? reflects the tensile storage modulus at 40° C. in GPa, ?Tg the width of the glass transition temperature in ° C., and X the cross-link density parameter in kPA/K all three parameters determined in a DMTA test at 11 Hz and a heating rate of 5° C./min.Type: GrantFiled: April 23, 2004Date of Patent: June 1, 2010Assignee: Nuplex Resins B.V.Inventors: Johannes Wilhemus Maria Schellekens, Martin Bosma, Freddy Gerhard Hendrikus Van Wijk, Paul Marie Vandevoorde
