Product Description

Cavity Sealant -D 330 KD1 A2- and Cavity Sealant -D 330 KD2 A1- are anti-corrosion agents containing solvents for sealing cavities with a high solid matter content.

As a thixotrope it has a well atomized solution and is therefore ideal for protecting areas that are difficult to access and narrow gaps between sheets of metal.

The cavity sealant infiltrates and pushes out moisture, it contains a high proportion of anti-rusting agent.

The cavity sealant atomizes very finely when sprayed, spreads very well, and penetrates all of the gaps to be protected (for example, welded joints), however, does not run too strongly out of the lower side of the weld.

The material can also be used at low temperatures above 10 °C (50 °F), and its flow characteristics are improved when the product and the bodywork are at room temperatures.

After drying, the material forms a plastic-like, waterproof film in a transparent beige color.

Application Instructions

Application

Is mostly used in garages for spraying the interior of cavities to supplement the cavity sealing for new vehicles and to treat cavity sealing after two to three years and in accident repair.

Note

Before starting to apply, it is necessary to read the safety measures and advice in the safety data sheet.

Even for products which are not required to be labeled by law, the usual safety measures must be observed for chemical emissions.

Cavity Sealant -D 330 KD1 A2- processing

The Cavity Sealant -D 330 KD1 A2- can be easily applied with the pressure feed spray gun and the appropriate probes.

The application pressure for the pressure feed spray gun is 5 to 6 bar. The material pressure reducer should be set to 5 bar.

If it is stored for a long time or if the temperature falls below +10 °C (+50 °F) the material becomes more thixotropic. This is broken however during spraying at the application temperature. The product shows its usual characteristics after spraying.

Note

Depending on the type of the cavity to be treated, the drying phase can last several days. Ensure that the vehicle is well ventilated during the drying process.

Cavity Sealant -D 330 KD2 A1- processing

Trim panels and trim should be removed. Any rust should be removed as far as possible.

For surfaces that are difficult to reach (such as semi-hollow spaces in doors) should be sprayed with the spraying hose from the lid instead of the spraying head.

The material should be at room temperature during application.

If it is stored for a long time or if the temperature falls below +10 °C (+50 °F) the material becomes more thixotropic. Shake the can thoroughly before use until the rattling of the balls becomes audible.

The body parts should be cleaned of dust and grease and then sprayed evenly. The can should be held in a vertical position when spraying.

When working with the “spraying hose”, it can be slowly guided in circles in all directions.

The spraying head with the round spraying nozzle enables the operator to apply a fine even coat on surfaces such as the underbody, giving these a perfect appearance.

Note

The Cavity Sealant -D 330 KD2 A1- is a product with a flammable propellant gas. Make sure that the cavities are well ventilated before closing again (for example, door trim panels) and that the vehicle is well ventilated during drying. Depending on the type of the cavity to be treated, the drying phase can last several days.

Caution

Do not spray functional parts such as the brake and exhaust systems.

Rubber and plastic parts should also not be sprayed.

Cleaning

Dripping cavity sealant can be easily wiped away.

The Plastic Cleaner -D 195 850 A1- is suitable for cleaning dried material.

Larger surfaces can be cleaned with a steam cleaner. Splashes on painted surfaces should be removed immediately.
