Important Information

As international harmonization of testing procedures progresses,
previously used national standards are increasingly being replaced by
ISO (DIN EN ISO) standards.
All information, recommendations and suggestions provided by Bakelite AG
in the form of verbal or written communication, or in pertinent data
bases, represent our best knowledge and experience. Such data are
non-binding in character, and do not represent, either explicitly or
implicitly,  assurances or a guarantee of specific properties. The
specified parameters merely represent typical data; they do not form a
basis for either a guarantee or a specification. The information,
recommendations and suggestions we provide describe our products and
possible applications in general or exemplary terms; they do not relate
to specific cases. The process of constant continued development and
improvement of our products can lead to changes in pertinent parameters,
texts and illustrations; no special mention is made of possible
alterations. Our technical advice does not free the customer of its
responsibility to verify our current information, in particular our
technical data sheets, safety data sheets and technical information
leaflets.

The customer will conduct its own tests of our products to determine
their suitability for the intended processes and uses, as well as to
establish that their processing properties are appropriate in the
pertinent situation, since our products may be used in a wide range of
technical applications that involve very different requirements
according to the specific situation. Therefore, such specific cases
are outside our control, and are the exclusive responsibility of the
customer. A pertinent agreement is necessary in case a binding assurance
of specific parameters is required. Customers and users of our products
must themselves observe possible patent rights, existing legislation
and regulations. This publication does not represent a license, nor
does it authorize infringement of any type of patent.

this subject. "Bakelite" is a registered brand of Bakelite AG in more
than 50 countries throughout the world. In the USA, "Bakelite" is a
registered brand of the Georgia Pacific Corporation. Bakelite AG is
licensed to use the brand name "Bakelite" for epoxy resins in the USA.
