These type of products are designed based on the high quality acrylic resins and are specially formulated for repair and car paint stain by fast drying time . the mixing ratio of these products with their hardeners by considering the shade and density are between 35 – 50 % ( based on the weight of paint ) . In each cases these ratio are inserted on the cans . The consumption of thinner based on the weight of the paint ( without considering the hardener ) are about 10 – 30 % . and recommended viscosity for applying and spraying the ready paint ( mix of 2 components ) in the 20°C and 50 ± 5 relative humidity is 15 – 17 seconds by Ford cup 4 .
Applying method :
First of all premix and hemogenize the paint . Than add its hardener by considering the mixing ratio and mix them . After well mixing paint and its hardener , add the proper thinner and remix them . The quantity of thinner depends on the proper spray viscosity . Apply this ready mix paint on the proper primed surface 2 – 3 times by flash time about 5 – 15 minutes . In each time the dry film thickness must be 10 – 15 microns . The approximately drying time is based on the following table .
