Product Description

CRC ALU H.T. HIGH TEMPERATURE ALUMINIUM COATING

GENERAL DESCRIPTION

High temperature aluminium coating.

A high temperature paint based on silicone resins and active aluminium pigments.Alu H.T. is designed to build a hard lasting finish that will not burn off, chip or peel at high temperatures.
FEATURES

• High thermal stability: resists temperatures up to 600C.
• Excellent coverage.
• High durability.
• Quick drying at room temperature.
• Very good resistance to temperature fluctuations.
• Good weather stability. Although some loss of gloss can be noticed after extended exposure.
• Totally lead and chromate free.
• No chlorinated and no aromatic solvents.
• Aerosols use dimethylether (DME) propellant for controlled application and film properties.

• Stove pipes
• Stoves
• Heaters
• Kilns
• Incinerators
• Chimneys
• Exhaust manifolds
• Headers
• Engines
• Ovens
• Steam pipes

• Shake aerosol can very well for at least one minute after agitator ball is free. Stir or mix bulk product well to obtain a homogeneous dispersion. Repeat frequently while using.
• Apply to a clean, degreased, dry surface for best results. Remove rust and scale with a wire brush.
• Apply in light, even coats; best results are obtained with 2 lighter rather than 1 heavy coat. Additional coats can be applied after 15-30 minutes.
• Complete curing occurs during use, typically after 1 h @ 200C or 45 min. @ 250C.
• When spraying is finished, clean aerosol valve by turning can upside down and pressing button until only propellant escapes. If clogging occurs, remove button and clean orifice with fine wire.
• Do not use on energised equipment. Use in well ventilated area.
• A safety data sheet (MSDS) according EU directive 93/112 is available for all CRC products.
