Description and Introduction
Omicure BC-120 (Boron Trichloride Amine Complex) cas 34762-90-8 by Huntsman is boron trichloride amine complex designed for adhesive applications. It is used as a latent curing
agent and accelerator in the aromatic amine, acid anhydride or dicyandiamide cure of epoxy resins. Omicure BC-120 is used in potting adhesives.
Omicure BC-120 (Boron Trichloride Amine Complex) cas 34762-90-8, a Lewis Acid, is intended for use as a room-temperature- latent elevated-temperature catalytic curing agent for
epoxy resins. BC-120, in combination with liquid epoxies, produces clear homogeneous formulations.
To incorporate BC-120, heat the resin to 30-35°C and stir in the curing agent.
When used to cure EPALLOY 7190 (DGEBA), where 1 to 9 phr BC-120 are typically used, room temperature shelf lives of greater than
one year can be realized. Curing can be accomplished at temperatures above 120°C. Higher temperatures reduce cure times. When using
3 phr Omicure BC-120 (Boron Trichloride Amine Complex) cas 34762-90-8 with 7190, and curing for 2 hours at 150 °C, a Tg of 120 °C was obtained. Using higher amounts of BC-120 will shorten
cure times and increase Tg
Higher Tgs can also be achieved by using epoxy novolac resins in place of 7190
BC-120 can also be used as an accelerator in the aromatic amine, acid anhydride or dicyandiamide cure of epoxy resins. The pot lives
of these formulations will be significantly longer than those obtained when using BF3 MEA or DMP-30 as the accelerator. Typically
0.5 to 1.0 phr BC-120 are used for acceleration.
Applications of Omicure BC-120 (Boron Trichloride Amine Complex) cas 34762-90-8
As a latent accelerator in the dicyandiamide cure of epoxy resins used in:
Electric enamels ? Filament winding ? Pultrusion
Health and safety precautions：
CAUTION: Omicure BC-120 (Boron Trichloride Amine Complex) cas 34762-90-8 is a highly acidic material.Avoid contact with skin or eyes as BC-120 may cause irritation and burning. Do
not inhale vapors. Use with adequate ventilation.Wash exposed skin and contaminated clothing after handling.
OMICURE BC-120 should be stored in tightly closed, acid-resistant containers. Avoid exposure to humidity. If upon opening a
container, BC-120 is found to be in its solid state, mild heating (about 100 °F) in a sealed container will remelt the product.
