SB 5050 MS Solvent Basecoat
DESCRIPTION
Base coat for solvent-based systems finished with the different BESA clearcoats for the bodywork or car refinish sector.
For applications and use in high quality jobs in bi-coat or tri-coat systems for metallic, pearl effect and solid colors. Combined with BESA putties, fillers and clearcoats, it guarantees a perfect vehicle finish, excellent gloss, aspect and durability.
It’s an easy-to-use system with a good performance, flexibility to repair and refinish any type of vehicle.
COLORS
Developed for the application of all solid, metallic, pearl and special effects colors of any car manufacturer worldwide, ensuring the accuracy of the color.
The color chart is sorted in chromatic order, which is a great help when matching the colors.
Furthermore, the use of the Spectrophotometer allows full access to the complete database, converting the color readings into the best and most accurate combination of colors.

APPLICATION INSTRUCTIONS
The application should start with a very thin layer to find out any possible mistake made during the preparation.
Continue with 1,5-2 regular coats for solid colors and 1 fade out control coat for effect, metallic or pearl colors. Flash-off between layers. With pearl and three-coat colors, apply thin layers until you achieve the original color. Prior to this, you must have applied the corresponding first coat which we advise to activate with 10% E-224 hardener.
With solid colors it’s very important not to exceed the recommended thickness in order to avoid thermoplastic phenomenon. It is recommended to activate the mixing 10% with E-224 hardener.
In spot repairs, it’s advisable to fade out. Apply the base coat to cover the repaired area, reduce the gun pressure and fade out the close areas. Flash-off until the whole area is evenly matt.
SURFACE PREPARATION
Degrease with SD-7/10, dry with a clean cloth and overpass a tack cloth.
It must be applied on thoroughly degreased surfaces and filled with BESACAR and BESAEXPRESS. On old paints or of unknown nature, it is recommended to apply a thin layer of the isolating filler BESAWET.
