FORTEGRA™ 100
Epoxy Toughener

Description
FORTEGRA™ 100 Epoxy Toughener is a low viscosity toughening agent designed for use
in amine cured epoxy systems.

Introduction
FORTEGRA 100 Epoxy Toughener is a low viscosity, high efficiency second phase
toughening agent designed for use in epoxy formulations. FORTEGRA 100 Epoxy
Toughener provides improved toughness without significantly affecting the viscosity, glass
transition temperature, corrosion resistance, cure rate or chemical resistance of the final
coating or composite.

FORTEGRA 100 Epoxy Toughener can be easily formulated into standard bisphenol A and
bisphenol F epoxy systems as it does not participate in the epoxy cure reaction.

As a second phase toughening agent, FORTEGRA 100 Epoxy Toughener is effective when
formulated at a specific volume fraction of the finished film or part. In a typical epoxy
formulation, 3% to 8% by dry volume is needed to achieve the toughening effect.

Typical
Applications
This product is suitable for use in applications such as:

Safety and
Handling
The Dow Chemical Company provides its customers with a product specific Material Safety
Data Sheet (MSDS) or Safety Data Sheet (SDS) to cover potential health effects, safe
handling, storage, use and disposal information. Dow strongly encourages its customers to
review the MSDS or SDS on its products and other materials prior to their use.

FORTEGRA™ 100 Epoxy Toughener is supplied in bulk, in 1200 kg intermediate bulk
container (IBC) or in 200 kg tight-head drums. The resin should be stored in a dry place
in its original closed packaging. FORTEGRA 100 Epoxy Toughener should retain its
chemical properties for a period of at least 12 months.

Product Handling
FORTEGRA 100 Epoxy Toughener is a homogenous material with some unique material
properties. Because of the high purity of the product, it may begin to crystallize and thus
become hazy and viscous if its temperature falls below 20°C. At temperatures below 15°C,
the material becomes very difficult to pump with common equipment. This situation is
entirely reversible by heating the product to 20°C. The following guidelines should be
followed for the effective handling of this product:
(a) FORTEGRA 100 Epoxy Toughener should be maintained above 20°C for at least 4
days prior to use to allow easy product transfer.
(b) FORTEGRA 100 Epoxy Toughener should not be exposed to temperatures below
15°C to prevent high levels of crystallization.
(c) FORTEGRA 100 Epoxy Toughener can be heated to 65°C for extended periods of time
without harming its toughening properties. Some oxidative discoloration may occur,
however, changing the product color to yellow or yellow/orange.

Product
Stewardship
The Dow Chemical Company has a fundamental concern for all who make, distribute, and
use its products, and for the environment in which we live. This concern is the basis of our
