President and CEO
Dr.
Dershem previously served as the Director of Basic Research for
Dexter-Loctite formerly Quantum Materials, Inc.(QMI). In this
capacity he oversaw the development of new polymer-based adhesives
for the electronics industry. Dr. Dershem holds over 39 US patents,
with additional applications currently under review.
Prior to joining QMI
in 1986, Dr. Dershem was involved in process engineering and product
development at Johnson-Matthey’s Material
Division. He has been instrumental in the development of novel silver/glass
die attach formulations, innovative thermoset adhesives, new solder
paste activator systems, mold releases, coupling agents, and numerous
coatings. He earned his doctorate in Physical Organic Chemistry
from Mississippi State University. He also earned his Bachelor’s
and Master’s degrees in Chemistry from San Diego State University.
During his tenure at
Dexter/Quantum, Dr. Dershem led a team of scientists in the development
of a unique liquid bismaleimide (BMI)
monomer for use in new lines of thermoset die attach adhesives.
This novel BMI allowed Dexter to make significant inroads into the
plastic die attach market. The liquid BMI monomer that was developed
has virtually no vapor pressure, is very hydrophobic, and can be
cured in as little as two seconds at 220 degrees Celsius. The new
BMI, furthermore, has a viscosity of around 1500 centipoise at room
temperature - a feature that eliminated any need for diluents. This
monomer has become the key workhorse component of all of Dexter’s
500 series adhesives.
In addition to maleimide chemistry, Dr. Dershem also has extensive
synthetic and application knowledge of several thermoset chemistries.
This set includes acrylates, itaconates, maleates, fumarates, styrenics,
vinyl ethers, epoxies, cyanate esters, benzoxazines, oxazolines,
propargyl ethers, norbornenes, episulfides, vinyl esters, allyl
compounds, and associated curatives.
