Opaque shades are compatible with all paint and resin systems, except water-based acrylic products.
These highly concentrated dyes are completely UV-resistant and offer excellent coverage.
In paints:
They are added to binders at 5 - 25%
In resins:
Opaque dyes for epoxy differ from transparent shades — they are completely opaque and block light even at low concentrations.
Their texture is viscous and thick.
Compatible with all epoxy, polyurethane and polyester resins
Use:
Being very concentrated, opaque shades must be mixed in small proportions, around 1–10% by weight of the resin mass.
The proportion depends on the casting thickness — in thicker layers, a smaller amount is sufficient due to the cumulative opacity effect.
The various shades are miscible with each other, allowing the creation of custom colours.
Dosage of Opaque Dyes (Epoxy Pigment Pastes)
Standard epoxy resins (types 4000 / WWA / 4010):
Recommended dosage: 5% by weight of the resin alone.
Add the colourant before mixing with the hardener to allow sufficient stirring time.
Water-based resin 1010:
DDose 5–10% of pigments by weight relative to the resin alone.
Mix the pigments first into the hardener 1014 to make them water-soluble, then add resin 1010.
It is always advisable to perform a test beforehand, as the correct dosage depends on pigment density and colour strength.
Note: The 1010 dry film is very thin, so its coverage is lighter.
⚠️ Important : The dye’s weight does not replace any portion of resin or hardener — it is added in addition.
