Heavy duty ambient temperature immersion paint and carbon remover

Dasic D53 has been developed for the rapid removal of many varied types of paint schemes and carbon deposits. Used at ambient temperatures, it can be used for cleaning ferrous, copper, aluminium and magnesium components without attack on the base metals.

APPLICATIONS

Dasic D53 should be used at ambient temperature in a mild steel tank with a removable mesh tray to facilitate removal of excess paint residues. A highly inhibited seal layer incorporated within the product will separate out onto the surface of the solution to reduce evaporation losses and act as a reservoir of corrosion inhibitors. This layer also acts as an effective rinse when work is withdrawn from the tank, thus ensuring the loss of active ingredients due to drag out, is kept to a minimum. On installation, the depth of the seal layer should be checked and, if necessary, water added to bring the layer depth to between 3 and 6 inches. The seal depth should be checked regularly to ensure that it is maintained at a minimum of 3 inches.

a) General Paint and Carbon Removal

The parts to be processed should be immersed below the inhibited seal layer of the material. The required processing time can vary from a few minutes for an air-dried acrylic to several hours for a stoved epoxy or polyurethane. Carbon removal usually requires from 2 to 12 hours.
After removal from the tank, the components are water rinsed, preferably using an air/water spray gun and dried. As Dasic D53 is an alkaline product with a highly inhibited surface seal layer, any subsequent rusting of ferrous components will be retarded, although the metal surface will be extremely clean and, therefore, reactive. If storage of the clean components is anticipated, they should be protected with Dasic E24 Dispen.

b) Examples of Typical Uses

De-carbonisation of engine parts after dismantling.
Removal of paint from aircraft landing gear components, wheels etc.
The cleaning of rubber moulds to remove carbonized residue of release agents and rubber gloves.
The removal of carbonized oil residues from process plants, oil heaters etc.

NOTE

Extreme caution should be exercised when opening all paint stripping containers, this includes the wearing of protective clothing and face visor.

PACKAGING
25 litre and 200 litre drums.

Paintblast D103

Specially processed and naturally occurring ligno-cellulose material designed for use with the Dasic Paintblast System. This material is considerably softer than plastic media and does not fuse onto substrate surfaces. It is, therefore, also a viable alternative to conventional dry stripping processes

Complete paint removal system for aircraft components
The complete removal of modern chemically resistant paint finishes from aircraft components without damage to both the substrate and existing pre-treatment process is presenting an ever-increasing problem.

The Dasic Paintblast system is designed to overcome this problem by combining the chemical action of specially formulated ambient temperature stripping solutions with that of mechanical impingement using a specialised range of blast equipment incorporating Dasic Paintblast D103 as an effective but safe media. This system has been developed by Dasic International Ltd., in conjunction with British Aerospace and has been widely accepted and adopted by aircraft and component manufacturers and operators.

The use of very high tensile steels in the construction of hydraulic landing gear, for example, limits the exposure of such components in paint stripping solution due to possible embrittlement and is often found necessary to utilise a heated stripping solution to obtain reasonable results. Further heat treatment is then required to ensure de-embrittlement. Finally, any cadmium plated parts have to be replated. The Dasic Paintblast system eliminates this long and costly processing procedure.
Further examples of paint removal utilising the Dasic Paintblast system are as follows:
The removal of high baked epoxy coatings from close tolerance aluminium and magnesium components without damage to the substrate.
The localised removal of protective finishes from airframe sections (anodised sections of wing areas, rivet heads, etc).
The removal of finishes from composite (glass or carbon fibre) components without removing the vital fibre bonding gel coatings, using Dasic D143 as the initial chemical stage. Dasic D143 is safe for use on composite materials and is approved to Def Stan 1443.

APPLICATIONS


Stage One:

Components are immersed in Dasic D53 or D590 tank products for a minimum period of 30 minutes. Alternatively, Dasic D23V, Dasic D550 or Dasic D143 application strippers may be used at this stage.If time is available, a prolonged immersion time will have the twin advantages of removing a large percentage of paint in most cases in addition to speeding up the subsequent blast stage.

Stage Two:

Rinsed and dried components are then progressed to a post immersion stripping using Dasic Paintblast D103 a specially processed and naturally occurring lignocellulose material in conventional shot blasting equipment. The following parameters are recommended:
Nozzle diameter of 8mm
Pressure 2/3 bars
Distance from work 10-20 cm
Time 30 - 60 seconds
The foregoing operation parameters have been determined by experience gained using Dasic Paintblast D103 media in the aviation industry and are intended as a general guide. Slight variation of operating techniques may be required to obtain optimum results on size, shape and type of article being processed.

The Dasic Paintblast System

The Dasic Paintblast System provides the complete package for the removal of chemically resistant coatings from complex aircraft components with maximum ease and without causing substrate damage. The Paintblast System utilises a choice of two immersion materials, either Dasic D53 or Dasic D560, followed by a water rinse and then a low pressure impact treatment in a cabinet utilising Dasic Paintblast D103 media.
