Chemistry KS3/4: How is paint made?

The uses of paint are described.

The constituents of an oil paint are described and the function of each ingredient is explained.

The differences between an oil paint and an emulsion paint are then explained. The raw materials are briefly described.

The process for making a variety of paints is fully automated.

Agitation at very high speed is needed in order to make sure that the ingredients are fully mixed.

Testing for quality control is also described and the clip ends with some examples of uses for ‘smart paints’.

Teacher Notes

KS4: Before showing the clip, students could be asked to suggest why paints are used, and how they clean brushes/rollers for different types of paints.

See if they can explain why some paints can be cleaned off using water and others need organic solvents (for example, white spirit).

Students can be asked to write down the ingredients of an oil paint and the purpose of each ingredient.

After watching the clip, ask students if they can think of other uses for smart paints and pigments (for example, thermochromic, photochromic or phosphorescent pigments).

Curriculum Notes

This clip will be relevant for teaching Chemistry.

This topic appears in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 in Scotland.
