A leading technology company in Denmark has developed
a new generation of solar panel with more energy than
standard solutions. United Adhesives' silicone based
electrically conductive adhesive, Silductor
6310, has successfully assisted the prototype build
of this photovoltaic technology. Click

United Adhesives' thermally
conductive adhesive ThermoBond
3519 that has high dielectric insulation property
has been applied in new
LED lighting system. It passes < 0.1 mA current
leakage requirement with 4000 Volts 60 Hz loading, which
provides superior energy saving capability beyond thermal
dissipation feature. |

United
Adhesives' Underfill 1230 has been adopted
in the GDP Global's WebFlow technology
for
fast and accurate dispensing:

New Product
Perfluoro Coating
& Potting
|
Specifically manufactured Perfluorocarbon based coatings
by United Adhesives are to provide superior protection of
electronic devices, such as dies, chips, PCBs, sensors,
etc., from the attacking of chemicals, acids, oils, fuels,
corrosive fluids, gasoline, and other corrosive medias.
Three coating products are ready for selection. PFC
9002 is a solvent-based product for spraying to form a thin-coated
layer. PFC9004 is a non-solvent, flowable version for dispensing
as conformal coating. PFC 9006 is a thixotropic non-sag
formulation for dispensing as "globe-top" encapsulation
on local parts such as chips, dies and components to provide
selective protection.
