A filler based on high quality acrylic resins with reduced VOC content. Thanks to a high spraying viscosity, the product can be applied in very thick layers that perfectly repair even relatively large scratches and irregularities on substrate. The filler can also be applied in a primer version in compliance with the guidelines of the EU Directive 2004/42/EC of 21 April 2004 on the limitation of emissions of volatile organic compounds. The product can be used as a primer for solventborne and waterborne basecoats. The product has an excellent adhesion to various types of substrates.
