Caparol Capacryl Haftprimer Adhesion Primer Black

Field of Application

For adhesion promoting priming coats on existing paint coatings, enamel coats, wood, zinc/galvanised surfaces, unplasticized (rigid) PVC, aluminium, copper and many other problematical substrates before applying acrylic or alkyd resin enamels. Do not use alkyd resin enamels on zinc/galvanised surfaces.

Suitable Substrates

Wood, derived timber products, zinc/galvanised substrates, aluminium, copper, unplasticized (rigid) PVC, stable existing coatings. Do not apply on anodised aluminium. The substrate must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion. Maximum permissible moisture content (WMC) in dimensionally stable wood: 13 %, in limited dimensionally stable wood and wooden parts of unstable shape: 15 %

Substrate Preparation

Wooden Parts: Sand the surface in fibre direction, clean thoroughly, remove all seeping wood contents, e.g. wood resin/rosin and resin galls (resin/pitch pockets). Cut sharp edges (see BFS Data Sheet No. 18).

Zinc, Unplasticized (Rigid) PVC: Wash with light ammonia solution using a sanding pad as per BFS Data Sheet No. 5 and No. 22.

Aluminium, Copper: Clean with destined detergents, e.g. Gescha Multi-Star, then sand with a plastic abrasive fleece (see BFS Data Sheet No. 6).

Existing Paint Coatings: Sand the surface of existing coats of paint and/or treat slightly with alkali. Remove unstable existing coatings.

Method of Application

Capacryl Haftprimer is ready for use and can be applied by brush, roller or spraying equipment. Stir well before use and dilute to a max. of 5 % with tap (potable) water, if necessary.

Consumption

Approx. 100 - 130 ml/m2 per coat. Consumption is only a guide value and may vary, depending on substrate requirements. Determine the exact amount of material required by coating a test area on site.
