Boron trifluoride ethylamine - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | boroethylamine trifluoride is a latent curing agent for epoxy resin. Because of the strong complex of boron fluoride and amines, amines become inactive. When heated, boron fluoride precipitates and amines solidify. The amount added is generally 1% of the epoxy resin, because the complex is easy to absorb moisture and must be weighed quickly. |
| Application | boron ethylamine trifluoride is mainly used as a latent curing agent for epoxy resins. |
| Application | latent curing agent for epoxy resin |
| category | toxic substances |
| toxicity grade | poisoning |
| Acute toxicity | intraperitoneal-mouse LDL0: 422 mg/kg |
| flammability hazard characteristics | toxic fluoride and nitrogen oxide gases emitted by heat |
| storage and transportation characteristics | The warehouse is ventilated and dried at low temperature; It is stored and transported separately from food raw materials |
| fire extinguishing agent | carbon dioxide, sand, foam, dry powder |
