OPAQUE PIGMENT 25ML

Our Opaque liquid pigments are designed to be compatible with most epoxy resins, polyurethane resins (rigid and elastomer) and polyurethane foams. Please conduct a small test with the material you intend to use to ensure compatibility.APPLICATIONThese liquid pigments are designed to rapidly disperse into the systems described above. We would recommend adding approximately 1/2% by weight of pigment to the material system. Some materials are naturally dark and/or opaque, and therefore it may be harder to achieve a specific colour. These materials may require anywhere from 1% to 5% of the pigment dispersion to develop the desired colour. Liquid pigments can often cause a negative effect on a material’s physical properties if too much pigment is added. Successful pigmentation is usually achieved when using the following guide:IN EPOXY RESIN SYSTEMSPigments are added to the “A” side (resin). If the hardener has darkened over time, a pigment dispersion of up to 5% by weight may be required.IN FLEXIBLE POLYURETHANE FOAMSAdd pigment to the “B” component. When working from large containers (5-gallons or drums), it is advisable to only pigment the amount of material to be used, especially if more than 2% is added. Stored materials may have a shelf-life reduction due to pigmentation.IN RIGID POLYURETHANE FOAM SYSTEMSThe pigment should be added to the “B” component. Due to the natural cream colour of most rigid foam systems, pigmentation is generally limited. For example, an opaque Black is likely to look Grey.IN AROMATIC SYSTEMSThe pigments are added to the “B” component. These systems are not colour stable. Lighter pigmented colors may darken slightly with age.IN ALIPHATIC SYSTEMSAdd pigment to the “B” component. These Water-Clear systems are easily pigmented and colour stable.STORAGEAmbient storage temperature – 18-27°C. Unopened containers will have a shelf-life of approximately 12 months when properly stored at recommended temperatures. Purge opened containers with dry nitrogen before re-sealing.Images are for illustration purposes only.Colour Chart Below.
