Notes for safe operation
Avoid contact with the skin and the eyes. Avoid inhaling vapor and smoke.
Do not approach the source of the fire.-smoking or open flames prohibited. Take measures to prevent static build-up.
Conditions for safe storage, including any incompatibilities
Store them in a cool place. Keep the container closed and store it in a dry and ventilated place.
Open containers must be carefully resealed and kept in vertical position to prevent leakage.
Recommended storage temperature: 2-8℃
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Tert-Butyl methacrylate (tert-BMA) can be used in the formation of homo and block copolymers by atom transfer radical polymerization (ATRP) for potential usage in coatings, biomaterials and flocculants.Used as coatings, fabric handling agents, insulating materials, etc.
