SENNELIER COBALT DRIER
This drier is so effective that an excess dose can cause the opposite effect. Therefore use sparingly (0.5% approx.) May slightly tint the colour. Contains cobalt, zirconium, zinc and calcium salts. Highly concentrated: use in small doses, i.e. a few drops for a knob of colour (less than 0.5%).
Any excess may cause difficulties during drying. Provides well-balanced drying of the oil colour, both on the surface and in depth. No effect on hue or gloss. Available in a 75ml jar. Price per jar.
