Acid-cured, chromate-free 2K primer, designed specifically for steel and aluminum
substrates for active corrosion protection.
– Excellent adhesion to iron, steel and galvanized substrates.
– Overlaps with all BIEL 1K and 2K systems
(except for epoxy coating systems and water-based base coatings).
– Can also be used for three-layer application
(KIS-21 / filler / top coat).
Ready to use!
The viscosity is achieved after the addition of a hardener.
Color: Translucent yellow-green
Consumption: 8-10 m2 /liter
2: 1 by volume (1:1 for large surfaces)
with the hardener KIS-21 (component B)
ready-to-use mixture for 12 hours at 20 ° C
Number of layers: 1-1. 5
Overlap: 30 min., max-8 hours
Surface for application:
– Galvanized steel
Thoroughly degrease the OP-01 degreaser with the product. Sand it with an abrasive.
Immediately before applying, degrease again.
Do not apply on thermoplastic substrates. Do not overlap polyester-based products.
The base should be clean, dry and fat-free. Lightly sand the surfaces.
Remove uncured old paint and primer coatings.
KIS-21 must be closed within 8 hours.
Protect the parts primed with KIS-21 from moisture.
Do not apply directly alkaline materials, such as, for example, EP-01,
EP-02M and EP-02C to KIS-21.
Do not keep leftovers in iron containers.
