June 9, 2011 – Dow Corning sealant and adhesive experts will be on hand
to discuss and collaborate upon the latest information and innovations
of durability testing, assessment and specifications for building and
construction sealants at the ASTM International Fourth Symposium on
Durability of Building and Construction Sealants June 16 and 17 in
Anaheim, Calif. The scope of the symposium covers all building
envelope, interior building, construction, and civil engineering
applications.

The following Dow Corning experts will present on a variety of key industry topics.
 
Andreas Wolf, senior scientist at Dow Corning Germany (and symposium chair) will discuss the preliminary evaluation of a
transparent structural silicone adhesive (TSSA), developed for
point-fixing in glazing, which combines high transparency, strong
adhesion performance, thermal stability and excellent weatherability.
The transparent film adhesive is a heat curing one-part material that
shows strong bonding to glass, metals, ceramics and even plastics
typically without primer. His presentation is titled Assessment of the Durability of
a Novel Transparent Structural Silicone Film Adhesive for Point-Fixing
in Glazing.
 
Larry Carbary, a scientist at Dow Corning U.S., will report on the
effects of glass bending on the durability of insulating glass units as
measured by frost point changes and visual changes after aging in a bent
condition.  The study seeks to address an architectural industry desire
to provide the unique and striking aesthetic effect of bent glass on
building facades.  His presentation: Durability of Cold Bent Insulating
Glass Units.
 
Kelly Broker, senior TSD specialist, Dow Corning U.S., will
report the results of a study where four-sided SSG insulating glass
curtain wall units were subjected to cyclic racking test methods in
accordance with AAMA 501.6 testing protocols. Test results including
sealant performance, sealant durability, and correlation of sealant
stresses with a Finite Element Model will be discussed. The presentation is called Racking Test Evaluation of Silicone Used in a Four-Sided Structural
Sealant Glazed Curtain Wall System.
 
Jinyoung Jung, AETS professional, Dow Corning Korea, will
provide a comparative evaluation of structural sealant glazing (SSG)
sealants commercially available in Korea according to ISO and ASTM
protocols. Currently, no standard specification or industry guideline
exists in Korea for the use of SSG. His talk will be Weathering Evaluation
for Structural Silicone Sealants Available in Korea.
