Description

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

PMMA (avg. Mol wt. ~350,000 g mol^-1) containing Fe₂O₃ and TiO₂ fillers have possible uses as flame retardants.

Pigment-wetting binder for coatings.

Features and Benefits

Contributes hardness, weather resistance, light fastness and resistance to chemicals.
