What Is This Antifreeze Used For?

Starbrite Premium Pink Antifreeze is formulated for winterising compatible engines and potable water systems. It is intended to protect systems that may otherwise be exposed to freezing temperatures while a boat, vehicle, property or pool is out of use.

Typical applications include:

Yes. Starbrite Premium Pink Antifreeze is supplied as a ready-to-use formula.

• Pour or introduce the product directly into the system as required by the applicable winterising procedure
• Do not add water
• Do not dilute the product
• Continue the relevant blow-through procedure until the bright pink fluid is visible at the required outlets

Diluting the product would alter the supplied concentration and temperature rating.

Why Is the Antifreeze Bright Pink?

The bright pink colour provides clear visual confirmation as the antifreeze passes through an engine, pipe, hose or potable water system.

This helps the operator identify when the product has reached the relevant outlets or sections of the system during the blow-through process.

Is It Suitable for Potable Water Systems?

Yes. The product is specifically described as a non-toxic antifreeze for winterising potable water systems.

It can be used in compatible water-system components containing:

• Aluminium
• Copper
• Brass
• Solder
• Rubber
• Seals
• Hoses
• Plastics

The product is intended for system winterisation. Follow the product label and equipment manufacturer’s instructions before returning a potable water system to normal use.

Does It Contain Alcohol?

No. The formula is alcohol-free and uses propylene glycol as its base.

The supplied product information does not list ethanol or another alcohol as part of the formula.

Does It Provide Corrosion Protection?

Yes. Starbrite Premium Pink Antifreeze contains corrosion inhibitors intended to protect:

• Metal engine and plumbing components
• Aluminium parts
• Copper and brass fittings
• Soldered joints
• Rubber components
• Seals
• Hoses
• Compatible plastic parts

These inhibitors provide additional protection to system components during winterisation.

Temperature Rating and Cold-Weather Guidance

• Product rating: -50°F / -46°C
• Colder-region guidance: For regions where temperatures fall below -10°F / -23°C, consider the higher-rated -100°F / -73°C version

The supplied guidance recommends the -100°F formulation for particularly cold regions, despite the stated -50°F rating of this product. Select the formulation according to the product label, expected local conditions and the system manufacturer’s instructions.

How Should It Be Checked with a Refractometer?

When checking this formula with a suitable refractometer, use the propylene glycol scale.

• Typical propylene glycol scale reading: +12°F to +16°F
• Required scale: Propylene glycol / PG

The stated refractometer reading is the typical instrument reading provided for this formula and should not be substituted for the product’s stated -50°F / -46°C rating.
