Procedure

For Matt finish incorporate Aluminum stearate or extenders. Charge all above ingredients in Ball mill/Attritor mill and mix it for 6 to 8 Hours and then check the grinding after running for 8 hrs, in Ball Mill/ Attritor Mill. If grinding is not completed properly, then run for another 2 to 3 hours till grinding is completed. Then check on Heggman Guage or on a panel. The paste should be free from specks. Then unload into open container. Add Silex 50(65%) - 10 kgs. + MS 4 to 5 Ltrs, to adjust the viscosity in B4 Ford Cup. The Viscosity should be 100-125 Secs at room temperature in B4 Ford Cup or as required. Combination drier 2% can be added.

If viscosity of paint is to be reduced, then add further mineral spirit to adjust the viscosity. If the resin quality has to be increased, the further resin to be added adjusting the pigment volume concentration and viscosity. For air-drying properties, add 2% combination driver as mentioned below to the final paint quantity. Then finally air-drying time and stoving at 100 c can be checked. If drying is to be improved, then increase the drier quantity. If gloss is more, then increase the quantity of Aluminum Stearate for getting Mat finish. If hardness is to be improved, then add 2 to 3% of any Long Oil Alkyd Resin in the initial stages. This will improve the hardness and drying properties.

Drying Time

Surface dry        -            30 – 40 Minutes.

Tack free            -            1 ˝  to 2 Hrs.

Note:   

Viscosity is measured in B4 Ford Cup. Combination Drier can be used as per the requirement. The Drier combination recommended can be varied depending on drying requirement. Mineral Spirits (M.S) or M.T.O or white spirit. The procedure given in No.1 Black paint is same for all above given formulations. It is advised to add antiskinning agent in all in formulations to avoid losses due to skinning. The other additives like slip, antifloating etc can be used as per manufacturers recommendations. In case of reactive pigments such as Zinc Chrome, Zinc oxide, basic lead sulphates etc it is advised that they are not ground along with the main pigments in the resin as their possibility of reaction. They should be added only in the end allowing slight grinding for proper dispersion.
