Field of Application

Suitable as additive for all types of alkyd enamels (alkyd resin varnishes), except water emulsified alkyd enamels, for adding 5 - 15 % by volume, if rigid and hard substrates are to be coated. For interior and exterior use. Particularly suitable to accelerate the drying of Capalac SolidGold and applicable as hardener for Capalac EffektLack, Hochglanz-Buntlack and Seidenmatt-Buntlack in the colour shades RAL 9006 and 9007.

Material Properties

  • Accelerates drying up to 40 %.
  • Enhances the resistance to chemical and mechanical loads.

Material Base / Vehicle

Isocyanate.

Packaging/Package Size

500 ml, 1 litre

Storage

Containers should be tightly closed and stored in a dry and cool, but frost-free place.

Density

Approx. 0.98 g/cm3

Note

The additive is colourless and reduces the opacity (hiding/covering power), depending on the amount of added hardener; viscosity is slightly diminished. The gloss level of silk/semi matt and silk gloss finish is slightly increased. For professional use only!

Substrate Preparation

For brush or roller application mix thoroughly 5 - 10 % by volume of additive into the alkyd resin enamel, depending on the desired drying acceleration and finish-hardness. Maximum additive quantity for spray application: 15 % by volume.

Note: Do not add more than 15 % by volume, respectively 5 % by volume if using Capalac Dickschichtlack!

Workability

Pot Life (Workability Time):
At +20 °C the pot life is 8 hours.
Note: The end of pot life is not visible.

Drying/Drying Time

At +20° C and 65 % relative humidity.
With reference to the drying time given for respective products, the drying time is considerably reduced with the following margins corresponding to the quantities of added product:
Addition of   5 volume per cent: about approx. 20 %
Addition of 10 volume per cent: about approx. 30 %
Addition of 15 volume per cent: about approx. 40 %.
