Axalta ViterClad Bonding Coat is a modified two pack epoxy adhesion and stabilising primer, specially formulated for the maintenance and repair of architectural cladding, in particular Corus Colorcoat HP200 cladding. Uses include as a primer for cladding stripped to the bondcoat or galvanised substrate, a patch primer for bare steel areas, and as an adhesion coat over existing cladding coatings, prior to the application of ViterClad PV or ViterClad 50.

Specially formulated for adhesion to stainless steel, carbon steel, galvanising, aluminium, copper, brass and PVF2, silicone polyester and other cladding types, Axalta ViterClad Bonding Coat has a wide colour range of over 350+ RAL and BS shades to suit all finishing shades.

The bonding coat cures down to 0℃ and is suitable for use as a blast/holding primer on blast cleaned cladding substrates.

Surface Preparation

• 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 Axalta Coating Systems for advice or contact Rawlins Technical on 0113 2455450 (option 2) or send a message to [email protected]. 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

Mixing

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.

• Base (3355) 3 parts by volume
• Hardener (4050 059) 1 part by volume

Thinner

1031 Thinner.

1031 Thinner can also be used to clean equipment.

Application Conditions

• Only apply in conditions of good ventilation which must be maintained during drying and curing.
• Do not apply in windy conditions where wind is likely to carry spray mist.
• 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℃ 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℃.
• Do not apply above 40℃.
• Do not apply over standing or running water or ice.

Application Methods

• Airless Spray: Output fluid pressure at tip 1500-2500 psi, Tip Size: 11-15 thou (0.28- 0.38mm)
• For application under cold or hot conditions, up to 5% addition of 1031 Thinner may be necessary
• Refer to Axalta Coating Systems ‘Epoxy Application and Curing Notes’

Product Notes
