DINITROL 81 hard wax 500 ml spray

Description

DINITROL 81 Spray protects steel, other metals and painted surfaces against corrosion, but unlike thicker underbody and cavity products it does not leave an opaque layer. Once the solvents have evaporated, a thin transparent wax film of approximately 25 μm remains on the part.

This means you can check the condition of the protected surface by eye at any time, without having to remove and reapply the protection.

Numbers and markings stay legible. On parts with a serial number, stamping or type plate there is no need for masking, you simply apply the protection over the whole surface.

The surface does not attract dust. The film dries hard, so dirt does not settle on stored parts the way it does on soft preservation waxes.

A solution for galvanic corrosion. Where two different metals meet and electrochemical corrosion is a risk, the wax layer seals the contact point off from moisture.

Dries in approximately 30 minutes. Parts are ready for handling or packing fairly quickly, which helps when shipping larger quantities.

Where It Pays Off Most

DINITROL 81 is most commonly used to preserve finished parts during storage and transport, where metal needs temporary protection but still has to be worked on or visually inspected.

It is also used in electrical installations, where a thicker opaque layer would get in the way of inspecting connections and terminals.

Surface Preparation

The substrate must be clean, dry and free from corrosion before application, as the wax will also preserve any rust that has not been removed first. Remove dirt, grease and any other residue that could impair the adhesion of the protective layer.

For degreasing before application, use DINITROL 7450 universal cleaner. Further products can be found in the surface preparation category.

How to Apply

• Clean and degrease the surface and let it dry
• Shake the can thoroughly before use
• Apply at 15–30 °C
• Apply an even wet coat of approximately 160 μm, which dries to approx. 25 μm
• Allow to dry for approximately 30 minutes

Note: this wax must not be painted over

DINITROL 81 is not a base coat for paint. If you need to renew or reinforce the protection, apply another coat of the same product.

Further anti-corrosion products for metal parts can be found in the DINITROL metal surface protection category.

Frequently Asked Questions – How long does the protection last?

It depends on the environment. Indoors and in storage it lasts considerably longer than when exposed to the weather outdoors. Because the layer is transparent, you can check its condition at any time and apply another coat as needed.

Can the wax be removed later?

Yes, the wax film can be removed with a standard hydrocarbon solvent such as white spirit or DINITROL 7450 universal cleaner.

How does it differ from DINITROL 4010?

Both leave a transparent film, but DINITROL 4010 withstands temperatures up to 200 °C and creeps into joints like a cavity wax, which makes it suitable for the engine bay. DINITROL 81 is a thinner preservation film (25 μm compared to 40 μm) intended mainly for the storage and transport of parts.
