Instructions for Use
Brush Application (Mix Ratio) |
N/A
SP350 Base : Volume - 8 parts, Weight - 100 parts SP350 Hardener : Volume - 1 part, Weight - 11 parts Mixing Procedure Remove the safety ring and press down on the cap to release the SP350 hardener. Shake the container for approximately 1 min. Remove the cap to be able to apply the SP350 primer with a suitable brush. If the material is not homogenous after 1 min shaking, please use a stick for further mixing (around 1 min) until the material is homogeneous. Do not hermetically close TUKS after mixing base and hardener. |

Application Recommendations
Number of Coats |
N/A With air spray gun, apply 1 wet coat to achieve 15 µm to 35 µm (0.6 to 1.4 mils) dry thickness. The number of coats depends on the size and the shape of the part on which it is being applied. The recommended dynamic air pressure is 1.5 bar to 4 bar (22 to 58 psi). |
Temperature |
N/A 15 to 59 ºC35 to 95 ºF |
Relative Humidity |
N/A 30 to 85 % |
Conditions |
N/A PRIMER SP350 may be applied in conditions outside of the limits shown above. Application must be done carefully to ensure a satisfactory result. Please contact your local AkzoNobel Aerospace Coatings representative to determine the appropriate application techniques when environmental conditions are outside of the recommended range. |
Equipment Recommendation |
N/A Gravity compressed air gun - Nozzle 0.8 mm to 1.8 mm. |
Note for Number of Coats |
N/A
If the thickness is too low:Apply a thin coat to obtain the desired thickness while respecting the recoating time. If the recoating time is exceeded, reactivate with an abrasive pad such as Scotch-Brite type A. If the thickness is too high:See your quality department. For micro-bubbles, runs or fish-eyes (depending on instructions given and type of part):Reactivate the surface using an abrasive paper grade 220 to 320, remove the dust and clean the surface using an approved cleaning solvent, apply a thin coat. In case of big default, non-conformity:Strip the part with an approved paint stripper (only on simple part) or strip by sand blasting (in this case, the surface treatment must be repeated). |
Cleaning of Equipment |
N/A Clean equipment with a suitable solvent such as Mapaero D713 or D760. Dispose of waste in accordance with regulations. |
Note for Cleaning of Equipment |
N/A
Spray with dry and oil-free air. The use of thinner SP350 Plus is highly recommended. |

Note for Drying Times |
N/A
SP350 primer must be cured at minimum 40°C (104°F) before applying XS420 TopcoatDrying times have been determined using test plates of a thickness < 2 mm and for 20 µm (0.8 mils) of dry film. Before accelerated drying = 70°C (158°F), leave to flash off for at least 15 minutes at room temperature. The "recoatable" time is determined with XS420 top coat.To recoat SP350 with other waterborne or solvent-based paints, contact us.The qualification test was performed at 23°C (73°F) ± 2°C/35°F for fully cured in 7 days. |
