ST. PAUL, Minn.,  Jan. 14, 2013  /PRNewswire/ --  H.B. Fuller Company  (NYSE:
FUL), a leading global adhesives provider, has expanded its family of materials
for the encapsulation and protection of electronic assemblies and components
with the launch of FH1438AB epoxy potting compound. Leveraging its extensive
formulating, applications and market knowledge, H.B. Fuller has completed the
comprehensive Underwriters Laboratories (UL) QMFZ2.E89705 Recognition Program
for FH1438AB potting compound to provide a highly flexible material that, in
turn, can potentially help finished goods manufacturers more quickly attain UL

This new addition to H.B. Fuller's electronic materials potting compounds is
tested and certified as a UL Recognized Component to meet the UL 94-V0 flame
rating. UL certification is a pre-requisite for encapsulation materials,
particularly those operating in harsh environments (e.g. saltwater and Fuel C),
when the application design requires the combination of flame retardancy, heat
resistance, dampening and vibration resistance properties.  

"We have seen an increasing demand for materials that meet the UL 94-V0
certification.  This UL 94-V0 certification gives our customers the confidence
to specify this material for use in electronic applications," said  Ralph
Velazquez, business development manager advanced materials at H.B. Fuller. This
material also provides a lower moisture vapor transmission rate (MVTR) than
other materials like silicones.

H.B. Fuller's FH1438AB potting compound is a two-part epoxy resin system. This
highly flexible material with a durometer value of 70 Shore 00 provides the
required protection to surface mount components (SMT) during a wide range of
temperature cycles without subjection to high stress levels. The potting
compound is also formulated with high resistance to age hardening, which
provides a consistent durometer measurement over time while maintaining
resistance to salt water and Fuel C.  It has excellent adhesion to many
substrates such as aluminum, most plastics and Viton fluoroelastomer with no
primer requirements.

In some instances, manufacturers using UL certified materials can bypass some or
all of their testing when seeking UL certification of their products, providing
assurance that their finished goods meet all standards. Typical applications for
this material are those where high reliability and flame prevention is critical
such as solid-state LED lighting modules, power supplies and automotive
