BS EN ISO 787-17:2019

What is ISO 787-17- Pigments and extenders about ?  

ISO 787 discusses general methods of test for pigments and extenders. ISO 787-17 belongs to ISO 787 multi-series and discusses comparison of lightening power of white pigments. 

ISO 787-17 specifies a general method of test for comparing the lightening (reducing) power of a white pigment with the lightening power of an agreed sample of the same type. 

Who is ISO 787-17- Pigments and extenders for ? 

ISO 787-17 on general methods of test for pigments and extenders is useful for: 

• Paint and Colour Manufacturers 
• Quality control personnel 

Why should you use ISO 787-17- Pigments and extenders ? 

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 such as durability, cost, and resistance to corrosion or wear. 

ISO 787-17 provides you with two procedures A and B. Procedure A is quicker than procedure B and is suitable for testing one sample of pigment; procedure B is better for testing several samples, especially if a pigment of unknown lightning power is being tested. ISO 787-17 helps you with the paint formulation and helps you in getting to good light colours.
