Non-brominated, Flame-retardant Aerospace Epoxies Introduced by Huntsman Advanced Materials
LOS ANGELES, May 3, 2005 – To meet stringent European Union environmental directives, Huntsman Advanced Materials has
developed a family of bromine-free, one- and two-component epoxy syntactics along with high-performance epoxy
laminating systems. The new Epocast® flame-retardant epoxies are formulated without including the chemical
components octabromodiphenyl ether (OBDE) and/OR pentabromodiphenyl ether (PBDE). Products that contain these
substances at levels of > 0.1 percent can no longer be sold or marketed in Europe. Nearly all of Huntsman Advanced
Materials’ non-OBDE/non-PBDE epoxy syntactics and laminating systems are qualified to leading aircraft manufacturers’
specifications governing materials used in the fabrication and repair of aircraft interior components.
According to Chris Mellings, Aerospace Marketing Manager at Huntsman Advanced Materials, “We are pleased to announce
our new OBDE- and PBDE-free, flame-retardant epoxies that combine good performance with sound environmental characteristics. The result of several years of research, Epocast® non-brominated syntactics and Epocast® epoxy laminating systems are representative of our continuing effort to provide customers with high-quality, leading-edge products.”
Bromine-free systems that are now part of the Huntsman Advanced Materials product line include:
- Low-density, two-component syntactics. Epocast® 1618-D/B syntactic is a low-flow paste that is qualified to
BMS 5-28, Type 18, Class 1. It features a 15-minute work life, 200°F (93°C) service temperature and 5,000 psi compressive
strength. In addition, low-density, non-brominated Epocast® 1633 syntactic products are now available in four different
colors and are qualified to both the BMS 5-28, Type 18, Class 2 and AIMS 08-08-001-04 specifications. Epocast® 1633
syntactic products have a 2-5 minute work life and exhibit a compressive strength of 6,500 psi.
- High-density, two-component syntactic. Epocast® 1636-A/B epoxy paste is qualified to the BMS 5-28, Type 6
specification. It has a two-hour work life, 350°F (177°C) service temperature and 15,000 psi compressive strength.
- Ultra-low density, one-component syntactic. Epocast® 1610-A1 is qualified to the BMS 5-28, Type 10 specification and
features a 30-day work life, a 200°F (93°C) service temperature, and a compressive strength of 2,400 psi.
- Medium-density, one-component frozen syntactic. Epocast® 1614-A1 epoxy paste is qualified to BMS 5-208, Type 14,
Class 1 and Class 2 as well as PWA 452 specifications. Featuring an eight-hour work life, the syntactic has a service
temperature of 350°F (177°C) and compressive strength of 14,500 psi.
- High-strength, one-component frozen syntactic. Epocast® 938-A1 syntactic is qualified to BMS 5-28, Type 13 and
Type 12, Class 1 and Class 2 specifications. It has a 24-hour work life, a service temperature of 350°F (177°C) and
compressive strength of 25,500 psi.
- Epoxy laminating systems. Epocast® 50-A1/Hardener 946 and Epocast® 50-A1/Hardener 9816 epoxy laminating materials
are qualified to BMS 8-201, Type 4 and Type 3 specifications respectively. They both have a service temperature of
200°F (93°C). The fast-setting Epocast® 50-A1/Hardener 946 system features a 15- to 20-minute work life; the slower
system, Epocast® 50-A1/Hardener 9816 epoxy laminating material, has a two-hour work life. Both products have compressive
strengths of 45,000 psi.
