    Default Durable Clear Sealant for Hand Painted Resin Pendant?

    Hi everyone,

    I make pendants out of resin which have hand painted details. I recently received one back for a repair as the chain had broken, and I noticed that some of the hand painted details have rubbed off already (after only a couple of weeks of being owned and worn)

    Right now I use several coatings of 'Humbrol Gloss Cote', which is solvent based, to seal in the hand painted areas and give an overall gloss finish.

    There's a chance that this customer has been particularly rough with hers given the breakage, but I'm wondering if anyone can recommend a clear sealant which is really tough and will not yellow?

    I just tried doing a test with crystal clear Araldite, but it sits on the surface and puddles. I've also tried using an enamelling 2 part resin, hand painted onto the surface, but that had the same problem where it separates.

    Any help or advice is really appreciated, thanks so much

    Obviously your decorative colours are not durable enough. Can you use a marque of colours with a recommended protective coat?

    Can you add a layer of clear (doming) resin over the top of your hand painted details? That is a technique I have seen other resin artists use. Something like these: https://www.resin8.co.uk/doming-resin-78-c.asp

    You could do some research into ceramic coatings similar to those used for car bodywork, gadget protection etc. They are expensive but the quantities used for jewellery making are so small that a bottle should last a while.

    Be mindful of shelf life though - some of them are very short once opened!

    Thank you very much for the responses everyone. The ceramic coatings sounds like a good call - something more industrial and less hobbyist which is made to last. I really appreciate the advice!

    Be assured that all the R&D expenditure invested in resin technology is spent to fulfil industrial long-lasting purpose. The subsequent hobbyist usefulness is a thankful by-product.

    As far as ceramic coatings go you could investigate the Italian product, Legor Kliar Line Nano-Ceramic E-Coating which is an electrically plated ceramic, available in clear as well as colours.

    Legor: http://products.legor.com/EN/item/3922

    The U.K. distributor for Legor is Balco: balco.co.uk

    The U.S.A. distributor is Rio Grande: https://www.riogrande.com/product/ce...sparent/204725

    The Rio Grande site will give you an idea of the plating and oven cooking setup you would need, which I'm sure similar could be obtained in U.K.

    I haven't (yet) tried it personally, just currently a side-line investigation on my part.

    As a solution for your pendants however, these e-ceramics would depend on the availability of a clear conductive lacquer to plate onto and the ability of the resin and paint to survive the plating and oven baking stages

    Well, it looks as if you will now have to do lots of experiments, some long winded, some very expensive, to find a hard coating which will not affect your art work.

    I hope you do, but you will then be reluctant to share the result. It will be your stock in trade, or trade secret, and you will be disinclined to give a leg-up to the opposition. Dennis.

    How are you painting these?
    In my mind are you pouring a thin layer, then painting when cured and then doming the top? It shouldnt wear then?
    Only ive done a few resin pieces but had to stop when i looked like elephant man with the reaction i had!!!
    I couldnt be bothered with finishing touches so used a good jewellery resin to save time.
