Colouring Araldite for cabinet repairs.
I wonder if anyone has tried colouring Araldite for cabinet repairs. I have a small early pocket Japanese transistor radio which has a large chip of plastic missing from the top back edge of the case. The case is an off white colour and I would like to have a go at repairing it. I had thought of putting some masking tape on the underside and filling in the gap with Araldite coloured white with something. Has anyone tried this and what can be mixed with Araldite without stopping it from hardening?

Re: Colouring Araldite for cabinet repairs.
Hi John. I am not sure about colouring araldite for cream cabinets, but with regards to those sets with mottled brown colours, someone suggested "Magic marker" felt pens black and orange colours (available from specialist art shops). I am not sure if there is one in cream, but I could find out for you.
There is a specialist shop in Headingley, Leeds, that sells "Magic marker" pens. All you do is dab the felt pen on to the araldite surface, and in the case of brown mottled bakelite repaired with araldite, start with the orange pen, and then put black dots in and around the orange coloured area - they "fuse" together and seem to create a brown and black dot effect, like the original. It might be worth a try, but I think that they are expensive Best regards Mike |

Re: Colouring Araldite for cabinet repairs.
I've had success by filing some of the original casing, from an unseen area, and mixing in the filings with the Araldite.

Re: Colouring Araldite for cabinet repairs.
You can buy usefull shades of fibreglass pigments from here; http://www.cfsnet.co.uk/acatalog/CFS...PASTES_11.html
However I have no idea if they would work with Araldite but it might be worth a try David |

Re: Colouring Araldite for cabinet repairs.
Hi,
I've had some success and 1 failure using acrylic paint (from tubes; as used by artists) to colour araldite. The tricky bit is in adding enough paint to make a 'solid' colour, without making the resultant 'solid' too pliable/friable. As a rough guide, 20% was too much acrylic paint; 10% was OK. I think I may have chosen the most difficult colour - white. It's possible that there may be some difference between 'quick setting' araldite, and the normal (24hour) setting stuff. I would guess that the quick setting would be a better bet, on the grounds of a 'stronger' catalyst. In any case, I would recommend using some 'former' to support the repair, if possible (fibre glass repairs for rusty cars - those were the days - used a metallic mesh as a skeleton). dave

Re: Colouring Araldite for cabinet repairs.
I think colouring Araldite is unlikely to work, given the small amounts of Araldite involved in a typical repair. Colour matching will be practically impossible - it's *extremely* difficult with fibreglass resin (and you're using much bigger volumes there).
Best regards, Paul |

Re: Colouring Araldite for cabinet repairs.
I tried the Araldite and bakelite filings idea quite recently,without much success.I would recommend however, casting gel.Ive had good results with this liquid and there are a range of colour pigment dyes for use with this product.The main drawback is that this stuff is expensive and once opened it has a very short shelf life.

Re: Colouring Araldite for cabinet repairs.
Araldite is very hard when fully set. Its adhesion to some plastics is 'iffy'. Have you thought about using Milliput? The superfine white is pretty good, No need for support: it has the consistency of stiff putty when mixed and can be easily shaped as it slowly hardens, using a water-wetted craft knife or similar sharp tool. I haven't tried mixing paint with it and I don't recommend the idea. Best if you let it set fully, level it to very smooth and touch in with paint, which Milliput will take very well.
I have added oil colour to casting resin with success when moulding knobs but there is a tendency for the colour to separate out during the hardening when rbuilding thin missing areas of cabinets. Milliput is obtainable from craft and art shops and some stationers. -Tony |

Re: Colouring Araldite for cabinet repairs.
I have managed to add poster paint to casting resin, and it worked fine. One of the old craft shops in Leeds recommended this, FWIW.

Re: Colouring Araldite for cabinet repairs.
For a good dense colour match you could try artists pastels, which are almost pure pigment with a little binding agent and available in an enormous range of colours. Grinding these into a powder and mixing with clear epoxy resin seems to work well.
The colours could also be blended with milliput to obtain the necessary colour match, but I have not had the chance to try this yet. |

Re: Colouring Araldite for cabinet repairs.
How about trying glass fibre resin?
I've only ever used this on cars before, but I suppose the principle should be the same. The resin could be coloured using either fibreglass pigment, or filings taken elsewhere from the case (as has already been proposed). I would think that this would be more workable than Araldite. You should be able to get glass fibre kits from Halfords and the like. Hope this helps. |

Re: Colouring Araldite for cabinet repairs.
Quite often I mix Araldite (precision, not rapid) with Humbrol enamel paint with good results. Just a drop of Humbrol is enough to mix with a sugar-lump sized quantity of Araldite mixture to get the right colour. The mixture takes twice as long to harden though so no peeking before it goes hard .
