ColorCote AlumiGard (formerly AR8)

AlumiGard is a pre-painted aluminium product, using a marine grade aluminium alloy substrate, for all roofing and cladding environments.

AlumiGard is suitable for use in ‘very severe’ marine environments, right up to the waterline, as well as chemical or acidic exposure in harsh industrial or geothermal areas.

For industrial environments where chemicals in the atmosphere may impact durability, AlumiGard X with 70% Polyvinylidene Flouride (PVDF) topcoat provides additional protection from chemicals along with the corrosion resistance of an aluminium substrate.

Key Features
  • Superior protection in the most extreme environments.
  • Marine grade aluminium alloy, as used in boat building.
  • Acrylic or polyester top coat baked on a polyester primer, giving an extremely durable paint system.
  • Provides excellent gloss and colour retention and resists UV damage.
  • Option of 70% PVDF top coat, for greater paint protection in industrial environments where corrosive chemicals are present.
  • Available in over 40 colours.
Scope of Use

AlumiGard and AlumiGard X have outstanding colour and gloss retention and are suitable for roofing, cladding, and rainwater goods.

AlumiGard is ideal for interior and exterior applications, including ‘very severe marine’ and industrial sites where there is a very high risk of deterioration from corrosive elements in the environment. These include salt-laden, geothermal and heavy industrial environments (particularly acidic/low ph).

Where there are corrosive chemicals present in the atmosphere (such as airports, gas stations or loading bays), it is advisable to use AlumiGard X, with a 70% PVDF topcoat.

If users are unsure about which substrate and paint system is right for the build, ColorCote provide an online warranty enquiry form to give you a recommendation and warranty timing.



Limitations on Use

Do not use a pitch less than three degrees (eight degrees for standard corrugated profile) to avoid ponding and premature degradation of the coating system.

Buildings which have a highly alkaline (high ph) environment such as dairy factories and abbatoirs which use caustic cleaners, as well as fertiliser processing and storage facilities, may be better suited to ColorCote MagnaFlow.

Please contact ColorCote if unsure which product to use.
