Causes

At temperatures above 180°F/82°C, conventional coating systems can rapidly discolour (‘yellow’). At temperatures above 200°F/93°C conventional coating systems are not recommended

Solution:

Domestic hot water systems, radiators and associated pipework etc can be decorated using conventional alkyd systems (>93ºC).

For superior resistance to ‘yellowing’, Crown Trade Acrylic Gloss/Eggshell systems can be used following appropriate surface preparation and priming.
