Glossy alkyd resin varnish, non-aromatic & cobalt free.
Suitable for interior use on radiators.

LV Texte

Field of Application

Suitable for intermediate and finishing coats on primed radiators and pipelines of hot water heating systems, indoors.
Note: For interior coatings on large (seamless) surfaces the use of acrylic enamel Capacryl Heizkörper-Lack is advisable, due to the product typical odour development of alkyd enamels
(alkyd resin varnishes).

Material Properties

  • Non-aromatic solvent.
  • Cobalt-free.
  • Very easy to apply.
  • Fast-drying.
  • High opacity (hiding/covering power), even on edges.
  • Heat-resistant up to 180 °C
  • Highly non-yellowing in hot water heating system areas < 60 °C
  • Superior flow.
  • High impact strength and shock resistance.
  • Resistant to common household detergents and short-term resistance against weak acids and alkalis.

Material Base / Vehicle

Alkyd resin with non-aromatic solvents.

Packaging/Package Size

375 ml, 750 ml, 2.5 litres, 10 litres



Note: The typical yellowing effect on the surface of white and light-coloured alkyd enamels may occur (caused by low UV radiation or chemical influences due to e.g. ammonia vapour from detergents, adhesives, paint or sealing compounds). This yellowing is no product defect and cannot be objected.
