Bitumen-Based Aluminium Paint | silvakote is a one-pack, aluminium pigmented bitumen solution.
A general purpose reflective aluminium paint for metallic, most bituminous and concrete surfaces.
- UV resistant.
- Highly reflective.
- Easy to apply.
Any surfaces to be coated with abe® silvakote should be clean, mechanically sound and dry.
Steel – should be free of rust and loose material as well as oil, grease and loose paint.
Galvanised steel – should be free of loose paint, grease and in the case of new material, free of anti-white rust treatment.
Bituminous surfaces and sheet waterproofing membranes – should be free of dust, chalking and any other loose material. New bituminous surfaces should weather for 8 weeks before coating.
Bonding / Priming
silvakote is normally applied directly to the surface but the following priming systems may be used where conditions so dictate.
Steel – etch primer.
Galvanised steel – no priming needed.
Bituminous surfaces – no priming needed except on ‘hungry’ sheet waterproofing membranes where a coat of bitu.®prime may be applied.
Typical Physical Properties of Dry Film
|Max. service temp||Dry 70°C|
|Weather resistance||Weathers well but dulls with age|
|Water resistance||Not recommended for immersion conditions|
|Solvent resistance||Will not withstand solvent spillage due to attack on bitumen|
|Chemical resistance||Film (aluminium) attacked by both acids and alkalis|
Steel and galvanised steel: 14 m2/1L @ 60 µm wft
Resulting dft: 20 µm
Bituminous surfaces: 6 – 8 m2/1L
Note: Due to the viscosity and aluminium pigments contained in silvakote this product exhibits both high spread and hiding characteristics. Low film build should, however, be avoided in the interests of longevity with due care during installation to apply the specified coating thickness.
silvakote may be applied by conventional spray or by brush or roller. On large applications it is often applied by soft broom or roofing mop. Coverage is very dependent on the porosity of the surface
