CRC ALU H.T. HIGH TEMPERATURE ALUMINIUM COATING

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 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.

APPLICATIONS

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

DIRECTIONS

• 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.

Superior High-Temperature Protection

CRC ALU H.T. High Temperature Aluminium Coating delivers reliable protection for metal surfaces exposed to extreme heat, up to 600C. This makes it an optimal choice for components like exhaust pipes, industrial machinery, and ductwork that operate at elevated temperatures. Its unique formulation resists oxidation and weathering, safeguarding against environmental damage and maintaining surface integrity over time.


Excellent Adhesion and Convenient Application

Formulated for strong adhesion, this aluminium coating bonds securely to clean, dry metal surfaces. Supplied as an aerosol spray, it ensures uniform coverage and ease of use, even on irregular shapes. Suitable for both industrial and automotive environments, each can is dimensioned for manageable handling and efficient spray patterns, delivering professional results with minimal effort.


Long-Lasting Performance and Compliance

CRC ALU H.T. Aluminium Coating is stored easily, with a shelf life of 24 months from manufacture when kept in a cool, dry location. Conforming to industry VOC regulations, it provides a safe, high-quality finish that protects valuable equipment from heat and the elements. Its robust weather resistance helps avoid costly repairs or replacements due to corrosion or oxidation.
