Insert Potting with
Huntsman Aerospace Products
Lightweight, high-performance materials from
Huntsman have long been preferred by leading
aircraft manufacturers and repair facilities to
reliably reinforce honeycomb composite panels
before inserting fasteners. The fasteners are used
to install components in composite floor panels,
galley walls, bulkheads and lavatory cabinets.
Among the epoxy syntactic systems frequently
specified for aircraft composite reinforcing are:
Epocast® 1618-D/B low-density epoxy syntactic,
Epocast® 1633-A/B low-density epoxy syntactic
and Epocast® 1652-A/B medium-density epoxy
syntactic. Uralane® 5774-A/B polyurethane
adhesive is also used for potting of inserts made
from materials such as Torlon® polyamide-imide.
The Huntsman insert potting materials are
either self-extinguishing or flame-retardant to
satisfy FAA regulations. Physical performance
properties include:
Qualified to Boeing,
Sikorsky and other
OEM specifications
Easy to handle viscosities
High strength
Ability to withstand
temperatures up to 350ºF,
depending on product
