CRC ALU H.T. HIGH TEMPERATURE ALUMINIUM COATING
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.
- High thermal stability: resists temperatures up to 600°C.
- 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
- Exhaust manifolds
- Steam pipes
TYPICAL(*) PRODUCT DATA (without propellant)
- 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 @ 200°C or 45 min. @ 250°C.
- 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.
