Universal acrylic paints for versatile exterior and interior use.

Field of Application

Emission-minimised and solvent-free exterior and interior paint for versatile use with outstanding adhesive strength on nearly all substrates. The special formula reduces the writing effect (stress whitening) for tinted paint coatings.
Suitable for weather-resistant exterior coatings on smooth and finely textured substrates, providing higher protection against aggressive air pollutants.
Universal facade paint for application on mineral renders of mortar groups PII and PIII, concrete, fair faced brickwork, fibre-cement boards, stable existing coats of paint, galvanised surfaces, unplasticized (rigid) PVC and wooden parts of unstable shape. Do not apply on ETICS/EWI systems.

For heavy-duty, scrub resistant, texture-retaining interior paint coatings. Particularly suitable for highly stressed coatings on Capaver glass fibre wall coverings and outstandingly suitable for dimly-lit halls, corridors, staircases, storerooms, workshops and underground car parks, due to a high light reflectance value.
Amphibolin is also available with a silk-gloss/mid-sheen gloss level (Amphibolin Gloss 20).
Amphibolin-W (facade paint) is provided with a preservative against deterioration in the coating film due to algal and fungal attack. Hence, do not use indoors.

Material Properties

  • Driving rain resistant, water-repellent according to German standard DIN 4108.
  • High adhesive strength.
  • Non-yellowing.
  • Alkali-resistant, hence unsaponifiable.
  • Thin film coating, texture-retaining.
  • Highly cleanable and resistant to aqueous disinfectants and household detergents.
  • Easy to apply.
  • Contains special pigments with photocatalytic effect.

Material Base / Vehicle

100 % pure acrylate. Synthetic dispersion/emulsion according to German standard DIN 55945, containing wet adhesion promoter to achieve optimum adhesive strength.

Packaging/Package Size

  • Standard Product: 2.5 l, 5 l and 12.5 l.  Airfix: 25 l hobbock, 120 l paint barrel, 480 l stainless steel container
  • "Red Sandstone" (Rotsandstein): 5 l
  • ColorExpress: 1.25 l, 2.5 l, 5 l, 7.5 l and 12.5 l




White and "Red Sandstone” (Amphibolin Gloss 20 is only available in White).

Amphibolin / Amphibolin Gloss 20 / Amphibolin-W can be tinted with CaparolColor or AmphiColor® (AVA) colourants. Add up to max. 10 % of colourants for application on non-absorbent substrates, e.g. unplasticized (rigid) PVC or galvanised surfaces. 
If more than one bucket is manually tinted, all product must be thoroughly mixed before use in order to avoid colour differences.
Amphibolin / Amphibolin-W: Quantities of 100 litres or more in individual colours may be ordered ready tinted ex factory.Amphibolin is tintable to all current colour collections via the ColorExpress tinting & mixing machine system. Amphibolin-W is tintable in light colours up to luminosity/lightness index (LI) approx. 70.
Check tinted product before applying to avoid colour differences. Always use tinted paint of same batch, when applying on seamless surfaces.
Brilliant, intensive colours may have a lower opacity (hiding/covering power). It is therefore advisable to apply a first coat in a similar hiding pastel tint, based on white. Possibly a second finishing coat may be necessary.

Colour Stability as per German BFS-Merkblatt (Data Sheet) No. 26:
(Binder) Class: A
(Pigmentation) Group: 1 - 3, depending on the colour.

The "wet adhesion promoter", embedded in Amphibolin as demonstrated in our laboratory test on glass plates, prevents the swelling up of binding agent in extremely moist conditions, so that the coatings are permanently prevented from blistering and flaking.
