Wacker has launched new anti- graffiti concentrate SILRES BS 710. Formulations based
on this product yield a protective silicone film that is long-lasting, elastic and
easy to clean. Any graffiti can simply be
washed off with water.
Stickers, posters or signs that have
been pasted onto walls can easily be removed as well. Coating materials made
of SILRES® BS 710 are permeable to
water vapor and form a permanent bond
with concrete, masonry and natural stone
without a primer coat. It is a one-part
silicone rubber formulation that cures to
form a silicone elastomer at room temperature and upon exposure to moisture.
It has a unique formulation concept,
which completely eliminates the need for
tin catalysts and oxime crosslinke and
contains no organotin compounds or oximes and is a low solvent formulation.
Coating materials made from SILRES
BS 710 can be sprayed onto surfaces or
applied with a roller or brush. A single
treatment is generally enough. Surfaces
will be reliably protected from graffiti
and posters after a curing time of one day.
According to Wacker, studies conducted on adhesive properties have shown
that porous mineral substrates like concrete or bricks do not need to be primed
prior to the application of a coating material made from SILRES® BS 710. The
silicone film is permeable to water vapor.
Dymax Introduces Multi-
Cure 9482-FC Very Low
Viscosity Conformal
Coating
Dymax Corporation has introduced
Multi-Cure 9482-FC, a new conformal
coating formulated with a revolutionary
new technology as an alternative to thin,
solvent-based conformal coatings. With a
viscosity of only 20 cP, this unique 100%
solids material provides a thin coating
that is more environmentally friendly
than solvent-based alternatives. The new
multi -cure, light and heat-curable film
coating provides good electrical insula-
tion properties as well as humidity, ther-
mal shock, and corrosion resistance.
Multi-Cure 9482-FC is designed for
rapid conformal coating of printed circuit
boards and other electronic assemblies.
Typically, to achieve a very thin conformal coating, formulations are reduced
using solvents. Until 9482-FC, light-cure
coatings have been unsuccessful in providing the thinness and performance requirements needed.
Compatible with most types of spray
equipment, 9452-FC fluoresces vivid
blue when exposed to UV light (365 nm)
for easy inspection of the coating coverage. It is also suitable for film coating or
flow coating application. In addition, its
secondary heat-cure feature allows the
coating to cure with heat in applications
where shadow areas exist. Another important feature of this very low viscosity
material, is its ability to be cured under
LED light in addition to broad spectrum
light, giving users the option of curing
systems for process optimization.
Ross Introduces Multi-
functional Mixing System
for Paste and Gel
Production
The Ross VersaMix Multi-Shaft Mixer is
ideal for mixing pastes, creams and gel-type products, with the capabilities of
powder dispersion, emulsification, dissolution, deagglomeration, homogenization, heating/cooling and deaeration. All
these functions are achieved in a closed
system, without the need for any transfer
steps.
Available is a 10-gallon Ross VersaMix
Model VMC- 10 rated for 29. 5”Hg vac-
uum up to 15 psi internal pressure. Its
Three-Wing Anchor (3HP), High Speed
Disperser (3HP) and High Shear Rotor/
Stator (3HP) operate independently at
different speed ranges to deliver excel-
lent uniformity in low to high viscosity
conditions up to several hundred thou-
sand centipoise.
All product contact surfaces are
stainless steel type 316L polished to
180 grit finish; elastomers are EPDM
and Chemraz (many other options are
available to ensure product and process compatibility).
The mixer cover includes multiple
ports for charging raw materials and installation of a vacuum/pressure transmitter, thermoprobe and tank light. It mates
with a jacketed cone-bottom vessel that is
designed for 100% discharge through a
flush diaphragm valve and easy portabil-ity. A 23” clearance from the valve outlet
to the floor allows operators to position a
bucket under the vessel to catch finished
product after the mixing cycle.
Ashland Unveils
Maxguard SCP
Ashland has introduced Maxguard SCP, a
new line of high-performance marine gelcoats that deliver multi-functional benefits including amazing beauty, unequaled
weatherability and long-lasting dependability that consumers and premium boat
builders alike have been seeking, the company reported.
“The exterior appearance of a boat
is critical to boat owners who typically invest a lot of resources and many
man-hours maintaining their vessel to
keep it looking beautiful. Ashland’s
gelcoats maintain their luster, protecting a boat’s finish for years,” said Ryan
Wilkins, Marine gelcoat product manager, North America.
The Maxguard SCP line of marine
gelcoats enhances a boat’s allure by exhibiting great depth of color. They are
formulated to enhance a boat’s finish
by providing unparalleled levels of UV-,
blush- and blister-resistance. In addition to its appearance and performance,
Maxguard SCP gelcoats offer excellent
application properties, great reparability,
and outstanding crack-resistance.CW
