摘要

Binder solution containing 0.5-5 wt% of an organic solution of (meth)acrylate copolymer with a solid content of 50-90 wt% and 0.005-1 wt% additive(s) in a solvent mixture comprising (cyclo)alkyl acetate, (cyclo)alkoxy-alkyl and/or (cyclo)alkoxy-cycloalkyl acetate, alkylaromatic with at least two 1-6C alkyl groups and a small amount of 1-6C alcohol. Binder solutions (I) contains: (A) 30-50 wt% 3-10C (cyclo)alkyl acetate(s); (B) 30-50 wt% (cyclo)alkoxyalkyl and/or (cyclo)alkoxycycloalkyl acetate(s) with 1-6C alkoxyl groups and 3-10C cycloalkoxy groups; (C) 10-30 wt% alkylaromatic(s) with at least two 1-6C alkyl groups; (D) 0.01-1 wt% 1-6C alcohol(s); (E) 0.005-1 wt% additive(s); and (F) 0.5-5 wt% of an organic solution of (meth)acrylate copolymer(s) with a solid content of 50-90 wt%. Independent claims are also included for: (a) a method for small automotive repairs by cleaning on and around the damaged area, rubbing down and cleaning again, optionally filling, rubbing down and cleaning again, coating with filler and drying or hardening, rubbing down and cleaning, applying a basecoat with a spray gun working inwards from the original paint, drying in air and optionally removing over spray, applying a clearcoat (wet-in-wet), applying the above binder solution (I) as spot blender and then hardening all the layers; (b) a spot repair set for training and for use in method (a), comprising a box made of metal or stable, scratch-resistant plastic, a foam insert at the bottom of the box with a depression in the center and two other depressions symmetrically to the right and left, a container filled with ready-to spray binder (I) in the central hole, two small spray guns in the other holes and a foam insert in the lid, with a handbook and a CD-ROM describing the method.
