Product Description

Axalta ViterClad Bonding Coat is a modified two pack epoxy adhesion and stabilising primer, specially formulated for the maintenance and repair of architectural cladding.

Best Uses

Axalta ViterClad Bonding Coat is recommended for the maintenance of Corus Colorcoat HP200 cladding. Axalta ViterClad Bonding Coat is also used as a primer for cladding stripped to the bondcoat or galvanised substrate. Available in a wide colour range to suit all finishing shades.

Axalta ViterClad Bonding Coat is ideal as:

  • A patch primer for bare steel areas
  • Suitable for PVDF
  • An adhesion coat over existing cladding coatings, prior to the application of Axalta ViterClad PV or Axalta ViterClad 50 (see relevant Product Data Sheets)
  • Specially formulated for adhesion to stainless steel, carbon steel, galvanising, aluminium, copper, brass and PVF2, silicone polyester and other cladding types
  • Cures down to 0°C and is tolerant of slight surface moisture during application
  • Suitable for use as a blast/holding primer on blast cleaned cladding substrates


Any very shiny or glossy bare metal areas, and all stainless steel, should be abraded to provide a key. Stripped bare metal areas must be free from stripper residues, metal salts, rust, debris and metal spatter – use suitable hand, mechanical or blast cleaning methods. Thoroughly degrease preferably using ViterClene ‘C’ bio-degradable degreaser, rinse with clean water and allow to dry before coating. As stripper residues can be difficult to detect, wash surface thoroughly with detergent and rinse with clean water if these may be present.

For aged/degraded Plastisol, condition diagnosis and correct surface preparation are critical to performance. Please refer to our technical team for advice. ViterClad Bonding Coat can be applied over leather-grain effect HP200 Plastisol, but is not recommended as a full coat over the newer type HPS200* (dimple-effect) Plastisol.
When using as a patch primer for bare areas with aged HPS200 cladding, overlap onto sound areas of HPS200 should be kept to a minimum. Surfaces should be clean, dry and free from all grease, oil and general contamination.

Mix only in the proportions stated, mixing each component individually then together using a mechanical agitator. Agitate periodically during use to ensure product remains homogeneous.

Only apply in conditions of good ventilation which must be maintained during drying and curing. Do not apply when rain, mist, sleet or snow are imminent. During application and drying time of the paint coating, the surface should be dry, the Relative Humidity should not exceed 85% and the steel temperature should remain at least 3°C above the dew point. Only apply this product when the above conditions can be maintained throughout the critical application and drying/curing process. Paint temperature should ideally be at a minimum of 15°C. Do not apply above 40oC. Do not apply over standing or running water or ice.
