General description
The thermal degradation behaviour of PMMA ( avg Mol. wt. ~350,000 g mol-1)was investigated in inert atmosphere, four weight loss steps were observed.
Application
Pigment-wetting binder for coatings.
PMMA (avg. Mol wt. ~350,000 g mol-1) containing Fe2O3 and TiO2 fillers have possible uses as flame retardants.
Features and Benefits
Contributes hardness, weather resistance, light fastness and resistance to chemicals.
