What is ISO 787-4-Pigments and extenders about?
ISO 787 discusses general methods of test for pigments and extenders. ISO 787-4 is the fourth part of the ISO 787 multi-series and discusses the determination of acidity or alkalinity of the aqueous extract.
ISO 787-4 specifies a general method of test for determining the acidity or alkalinity of the aqueous extract of a sample of pigment or extender.
Note: When this general method in ISO 787-4 is applicable to a given pigment or extender, only a cross-reference to it should be included in the International Standard relating to that pigment or extender, with a note of any detailed modification which may be needed in view of the special properties of the material in question. Only when this general method in ISO 787-4 is not applicable to a particular material should a special method for the determination of acidity or alkalinity be specified.
Who is ISO 787-4-Pigments and extenders for?
ISO 787-4 on general methods of test for pigments and extenders is useful for:
- Paint manufacturers
- Quality control personnel
Why should you use ISO 787-4 -Pigments and extenders?
Pigments, dyes, and extenders are incorporated in binders to obtain decorative effects (e.g., color, gloss, dulling) or functional effects (e.g., corrosion protection) on a surface coating.
ISO 787-4 provides you guidance with sampling, test procedures, and expression of results for determining the acidity or alkalinity of the aqueous extract of a sample of pigment or extender. The test procedures include test solution, determination.
ISO 787-4 helps to improve the quality of your coatings by determining the acidity or alkalinity of pigment or extender.
