Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.

Thinner 1033 and 1035
Application method

Airless spraying, air assisted airless spraying and conventional spraying.

 

Airless application with the viscosity 20–40 s (DIN 4) can be reached with approximately 0–20 % of thinning. Nozzle tip 0.011"–0.015" and the nozzle pressure 100–140 bar. Spray angle shall be chosen according to the shape of the object.

 

Air assisted airless application with the viscosity 20–40 s (DIN 4) can be reached with approximately 0–20 % of thinning. Nozzle tip 0.011"–0.015" and the nozzle pressure 40–120 bar. Atomising air pressure is recommended to be used with pressure 2–3 bar. Spray angle shall be chosen according to the shape of the object.

 

Conventional application with the viscosity 20–40 s (DIN 4) can be reached with approximately 0–20 % of thinning. Nozzle tip 1.4–1.8 mm is recommended to be used with pressure 2–3 bar.

APPLICATION DETAILS
Application conditions The surface to be treated has to be clean and dry. During application and drying the temperature of the air, the surface to be treated and the lacquer has to be over +18ºC and the relative humidity of the air below 70%.
Preparation Wood surfaces should be sanded with sandpaper P150–240. Lacquered surfaces should be sanded with sandpaper P240–400. All sanding dust must be removed before lacquering.
Mixing of components Stir the lacquer carefully before use. Thin the lacquer to the viscosity required with Thinner 1033 or 1035.

Do not use iron containers as mixing container. Instead use plastic, enamel or acid resistant steel containers.
Cleaning of tools Thinner 1033 or 1035.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 640 g/l of paint.
Maximum VOC content in ready to use paint (thinned 20 % by volume) is 670 g/l.

HEALTH AND SAFETY LABELLING
according to Regulation (EC) No. 1272/2008
Containers are provided with safety labels, which should be observed. Further information about hazardous influences and protection are detailed in individual health and safety data sheets. A health and safety data sheet is available on request from Tikkurila Oyj. For industrial use only.
