Description
We have 6 high quality translucent tinting pigments ideal for creating subtle tints or translucent colouring of water-clear casting resins including polyester, polyurethane and epoxy casting resins.
The pack of 6 comprises of 6 vivid colours ideal for tinting or pigmenting jewellery, sculptures and design prototypes with anywhere between a faint hint of colour to a very strong, yet still translucent colour.
All that is needed is a tiny drop of these specially developed pigments to add translucent colour effects to resin castings, each 25ml bottle is enough to tint large quantities of resin. A subtle tinting effect can be achieved with less than 0.0004% – i.e. 1 droplet in a 35g casting, each bottle is capable of tinting approximately 40kgs of resin
The pack of 10 consists of our most popular colours, which include:
- Red
- Prussian Blue
- Green
- Purple
- Burnt Sienna
- Blue
- Yellow
- Black
- Orange
- Turquoise
The translucent pigments are compatible with:
Polyurethane casting resins such as water clear GlassCast casting resin, polyurethane the water clear polyester casting resins such as water clear polyester casting resin. Epoxy resins such as our epoxy coating resin and epoxy laminating resin.
How to Use
When using these colours, tinting clear resins you should use only a tiny amount of the translucent pigments i.e. x 1 droplet is enough to pigment around 20-40g of resin, depending on how strong you want the colour tint to be.
Remember that thicker castings will require a lower percentage of pigment because the tint will appear stronger the thicker the section is. Conversely, thinner castings will require a higher percentage of pigment in order to appear to be the same colour as thicker castings.
Suggested mixing ratio
Most scales are incapable of the accuracy required to measure pigment ratios of around 0.005%, we recommend as a guide is using the table below. However in all cases experimenting yourself by adding a tiny amount of pigment at a time until you achieve the desired level of tint you require.
Suggested Mixing Ratio Table
Mixing the Pigments / Colours
In most cases the coloured pigments will disperse very quickly into epoxy resin and polyurethane resin. When using the pigments to tint larger quantities of polyester resin it is recommended to make a resin ‘dispersion’ by mixing the pigment into a small amount of the resin first and then mixing the small pigmented batch of resin into the larger batch to aid distribution of the pigment throughout the resin.
When colouring / pigmenting more reactive materials such as fast curing polyurethanes you will find it helpful to mix the pigment into one side of the resin, either part A or part B, thoroughly before mixing the two parts together and starting the reaction. This allows as much time as is needed to thoroughly disperse the pigment before starting the reaction.
Supplied in a pack of 10, also in a smaller pack of 6
