As scale modelling acrylic paint Thinners and Cleaners are relatively expensive in comparison to volume, eg. 17ml Thinner $5, 85ml Cleaner $6.99, I aim to make my own. According to the Plastics Identification Code (PIC) below, PET bottles (Code 1) are solvent (eg. IPA) resistant. They are therefore ideal although expensive when postage costs are added and difficult to find. My research indicates Codes 2 & 4 may be suitable for mixtures of IPA/Distilled Water/Windex at the follow ratios:
Thinner:
1/2 cup (4ozs) Distilled Water
1/4 cup (2ozs) IPA
10 drops Acrylic Retarder
10 drops Flow Improver
Cleaner:
50% Windex
40% Distilled Water
10% IPA
10 drops of Glycerine
Plastics Identification Codes:
1 – Polyethylene Terephthalate (PET) is a clear, tough, solvent resistant plastic.
2 – High Density Polyethylene (HDPE) is a common plastic found in soft & rigid plastic forms. In rigid form is usually white or coloured, used for milk bottles, shampoo bottles & cleaning products.
3 – Polyvinyl Chloride (PVC) is found in pipes, toys, furniture and packaging but contains harmful chemicals.
4 – Low Density Polyethylene (LDPE) is usually a soft, flexible plastic used for different kinds of wrapping, bread bags, produce bags & bin bags.
5 – Polypropylene (PP) is a hard but flexible plastic used for ice cream containers, lids & plastic take away containers.
6 – Polystyrene (PS) is also known as Styrofoam is used to make cups, foam food trays and packing materials.
Is there a fellow contributor sufficiently competent to advise the suitability of LDPE and HDPE?
