What is ISO 787-5 – Oil absorption value of pigments and extenders about?
ISO 787-5 discusses pigments and extenders. The aim of the ISO 787 series is to provide best industry practices for pigments and extenders that helps in determining the characteristics of paints.
ISO 787-5 is the fifth part of the ISO 787 series of standards that specifies a general method of test for determining the density of a sample of pigment or extender, using a centrifuge to remove entrained air.
Who is ISO 787-5 – Oil absorption value of pigments and extenders for?
ISO 787-5 on pigments and extenders is useful for
- Pigments and extenders manufacturers
- Paint manufacturers
- Quality control personnel
- Product development teams
Why should you use ISO 787-5 - – Oil absorption value of pigments and extenders for?
An extender pigment is a naturally occurring chemical substance (usually having a white color) that is added to paint or coating to improve its properties. The oil absorption value has an important guiding significance for the selection of extender, and it directly affects the cost and processing performance of the molding compound.
ISO 787-5 provides you with a test to determine the tamped volume and density of pigment or extender. ISO 787-5 also guides you with sampling, test procedures, and test reports.
If you are a manufacturer, ISO 787-5 can help you to improve the flow properties of your paints and other properties such as durability, cost, and resistance to corrosion or wear.
