Master Bond launches conformal coating
Master Bond’s new Master Sil 773 PCB
conformal coating cures tack-free in less
than five minutes.
Master Bond has developed a rapid tack-free, ready-to-use silicone conformal
coating called Master Sil 773, formulated to provide protection to electronic circuitry in high humidity environments as
well as upon exposure to shock and
vibration. It cures quickly at ambient
temperatures to a flexible, transparent,
low hardness silicone coating. Master Sil
773 maintains its low modulus over the
a wide temperature range of -65°C to in
excess of +200°C. This one part, ultra low
viscosity silicone adhesive is ideal for
application as a low stress coating
affording protection to sensitive board
components in demanding environments. Master Sil 773 is 100% reactive
and cures by the moisture mechanism. If
needed, a UV tracer dye is also available
with this system. The Master Sil 773 silicone conformal coating can be applied
by dipping, spraying, brushing.
SHERWIN-WILLIAMS’ NEW
ANTI-GRAFFITI CLEAR COAT
Sherwin-Williams Protective & Marine
Coatings has introduced Anti-Graffiti
Clear Coat, a single-component, low
VOC (less than 250 grams per liter), non-sacrificial elastomeric siloxane coating
for new or previously-coated concrete
substrates. Requiring only a solvent
wipe cleaning or using a 3000-psi pressure washer to remove graffiti, the new
coating is intended to protect bridges,
overpasses, concrete fences and railcars,
as well as commercial buildings, schools
and transit stations, from defacement by
spray paint and permanent marker. The
moisture-cure coating could be dry to the
touch in as little as 30 minutes, depending on temperature, humidity and film
thickness. According to Sherwin-Williams, after 4,000 hours of accelerated
weathering testing and multiple graffiti
applications and removals, Anti-Graffiti
Clear Coat left no signs of graffiti or
staining after clean-up, and no signs of
streaking, cracking, pinholing, discoloration or other degradation to the coating surface upon casual examination.
GLASURIT’S NEW 925-2002 HS
CLEAR ULTRA SCRATCH-RESISTANT
Glasurit has introduced its new 925-
2002 HS Clear, which was specially
developed and approved for refinishing
Toyota’s scratch-resistant OEM coatings
applied on Lexus models. The new product meets all of Toyota’s specific requirements—ranging from scratch-resistance
to long-term gloss retention and applicability in the spot-repair process. After
400 hours of Xenon weathering and the
Amtec scratch test, the HS Clear exhibited gloss retention of more than 80%,
which is attributable to the product’s
reflow technology, according to the company. With a VOC content of 405 grams
per liter, the product complies with
European legislation. It is compatible
with the Glasurit 90 Line waterborne
and its properties can be adjusted by
means of the company’s new 929-2002
Hardener and standard additives.
HONEYWELL LAUNCHES NEW
MATERIAL TO IMPROVE EFFICIENCY,
POWER OUTPUT OF SOLAR PANELS
Honeywell Electronic Materials has
introduced a new material designed to
improve the efficiency and power output
of photovoltaic (PV) panels. Designed to
optimize light transmittance through
glass that covers PV panels, Solarc
transparent coating helps maximize PV
module efficiency and power output. The
coating also minimizes glare from glass,
allowing PV panels to blend with surroundings. Compatible with spray, roller,
curtain, slot-die and spin-on coating
processes, the liquid-based coating protects glass in hot and humid conditions
and enables anti-soiling and self-cleaning functionality that prevents dust
accumulation. CW
