Volkswagen Golf Service & Repair Manual: Cavity-preservative agent

Designation:

Cavity-preservative agent -D 330 KD1 A2-

Cavity-preservative agent -D 330 KD2 A1-

Issued 04.2010

Product description

Cavity-preservative agent -D 330 KD1 A2- and cavity-preservative agent -D 330 KD2 A1- are solvent-based, high solid-content corrosion inhibitors for sealing cavities. It is a thixotropic solution with good atomizing properties, ideal for protecting areas that are difficult to access such as narrow gaps between panels. This cavity protectant infiltrates and displaces moisture and contains a high proportion of rust inhibitors. The cavity protectant is very finely atomized during spraying, has outstanding creep properties, penetrates well into narrow gaps (such as welded seams) which need protection but does not run significantly out of seams. The material can be applied even at low temperatures above 10 °C, but its creep properties improve when the product and the bodywork are at ambient temperature. When completely dry, this product forms a waxy film which is plastic, water-repellent and nearly transparent beige.

Technical data sheet

Application

Mostly used in the workshop for spraying the interior of cavities to supplement the cavity sealing of new vehicles and to restore cavity sealing after 2-3 years as well as after accident repair. Note Before using, read the safety measures and recommendations in the safety data sheet. Even for products which are not required by law to be labelled, the usual safety measures for chemical products must be observed.

Application of cavity-protection agent -D 330 KD1 A2-

The cavity-protection agent -D 330 KD1 A2- can be easily applied using the pressure-feed spray gun and the appropriate probes. The operating pressure of the pressure-feed spray gun is 5-6 bar. The material pressure reducer should be set to 5 bar. If the material is stored for a long time or if the temperature falls below +10 °C, it becomes more thixotropic. However, this will be reduced again during spraying at working temperature. The product also displays its normal properties after spraying.

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

Application of cavity-protection agent -D 330 KD2 A1-

All trim parts are to be removed. Any existing rust is to be removed as completely as possible. To treat hard-to-reach surfaces (e.g. partial cavities in doors etc.), the spray nozzle is replaced by the spray tube in the cap.

The material should be at ambient temperature during application.

If the material is stored for a long time or if the temperature falls below +10 °C, it becomes more thixotropic. Therefore, the can must be vigorously shaken before use so that the rattling of the ball can be heard. The body parts should be cleaned of dust and grease and then sprayed evenly. The can should be held vertically when spraying. When working with the “spray tube”, it can be slowly guided in circles in all directions. The spray head with the round spray nozzle enables the application of a fine, even coat on surfaces such as vehicle underbodies, giving these a perfect appearance.

Note Cavity-protection agent -D 330 KD2 A1- contains flammable propellant. Ensure that cavities as well as the entire vehicle are well ventilated during the drying period before they are closed again, for example, with door trim. Depending on the type of cavity to be treated, the drying phase can last several days.

Caution

Functional components such as brake and exhaust systems are not to be sprayed.

In addition, rubber and plastic parts are not to be sprayed.

Cleaning

Preservative which drips out can be easily wiped away.

Plastic cleaner -D 195 850 A1- is suitable for removing dried material.

Larger areas may be cleaned with a high-pressure steam cleaner. Splashes on painted surfaces should be removed immediately.
