BITUMEN-BASED ALUMINIUM PAINT

silvakote

DESCRIPTION TYPICAL

silvakote is a one-pack, aluminium pigmented

bitumen solution.

USES

A general purpose reﬂective aluminium paint for metallic, most bituminous and concrete surfaces.

ADVANTAGE S

• UV resistant.

• Highly reﬂective.

• Easy to apply.

SURFACE PREPARATION

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.

MIXING

As the aluminium pigment settles very easily silvakote must be stirred well before use, using a ﬂat paddle. All settled material must be thoroughly dispersed. Keep silvakote well stirred during use.

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.

APPLICATION

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.

CLEANING

Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.

PROTECTION ON COMPLETION

It may be necessary to apply a further coat of silvakote after three years.

TEMPERATURE AND RELATIVE HUMIDITY

Application temperature range:

5°C to 50°C. Do not apply if surface is less than 2°C above dew point.

MODEL SPECIFICATION

Bituminous aluminium paint for metallic, concrete and waterproofed surfaces.

The aluminium paint will be silvakote, a one-component, aluminium reﬂective coating applied in accordance with the recommendations of a.b.e.® Construction Chemicals, including bitu.®prime where necessary.

PACKAGING

1L, 5 L, 25 L, 200L containers.

HANDLING & STORAGE

This product has a shelf life of 12 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.

HEALTH & SAFETY

Wet silvakote is ﬂammable and naked ﬂames should not be allowed in the vicinity of the work area. Adequate ventilation must be provided when working in conﬁned areas. Always wear gloves when working with the material and avoid excessive inhalation and skin contact. If material is splashed into the eye, wash with plenty of clean water and seek medical attention.

Cured silvakote is inert and harmless.
