Accelerator DY Advanced Materials A LATENT CURING AGENT / ACCELERATOR GENERAL :

Transcription

1 Advanced Materials Accelerator DY 9577 A LATENT CURING AGENT / ACCELERATOR GENERAL : Accelerator DY 9577 is a boron trichloride-amine complex, which may be used either as a latent catalytic curing agent for liquid epoxy resins or as a latent accelerator for anhydride cured epoxy resins. CHEMICAL DESCRIPTION : Accelerator DY 9577 is a boron trichloride-amine complex. APPLICATIONS : Casting Encapsulation Filament winding Pultrusion Molding Electric tapes ADVANTAGES : Exceptional latency at temperatures up to 80 C Highly reactive at temperatures above 120 C Does not degrade electrical properties of cured system Soluble in liquid epoxy resins and hardeners Stabilizes pre-accelerated resins and hardener TYPICAL PROPERTIES * : Visual Appearance Amber/brown semi-solid Melting Point, C ( F) ( ) Water Content, %, max C (77 F), g/cm 3 (lb/gal.) 1.1 (9.2) * Typical properties are based on Huntsman s test methods.

2 FORMULATIONS : The amount of Accelerator DY 9577 used in any formulation will depend on the resin and hardener used and the reactivity required. In general, when Accelerator DY 9577 is used as a catalytic curing agent, 1 to 5 phr * will suffice. When used as an accelerator for anhydride cured systems, concentration of 0.1 to 1 phr of Accelerator DY 9577 is usually sufficient. * Parts per 100 parts of resin October 2007 Accelerator DY9577 Page 2/8

It should be stored in sealed containers at temperatures not exceeding 40 C. Containers should be kept closed to prevent moisture absorption and contamination. HANDLING/SAFETY PRECAUTIONS : Caution may cause irritation. May be harmful if swallowed or inhaled. Avoid contact with eyes, skin or clothing Avoid inhaling vapor Use with adequate ventilation Wash after handling Store in cool area in tightly closed containers to prevent contamination and water absorption. Read Material Safety Data Sheet Before Using. For Industrial Use Only. October 2007 Accelerator DY9577 Page 6/8

7 Caution To protect against any potential health risks presented by our products, the use of proper personal protective equipment (PPE) is recommended. Eye and skin protection is normally advised. Respiratory protection may be needed if mechanical ventilation is not available or is insufficient to remove vapors. For detailed PPE recommendations and exposure control options consult the product MSDS or a Huntsman EHS representative. FIRST AID : In case of contact : Eyes : Promptly flush eyes with water for at least 15 minutes. Skin : Promptly wash with mild soap and water Inhalation : Remove to fresh air. Give oxygen if breathing is difficult. Ingestion : If conscious, give large quantities of water to drink. Call a physician.
