Troy Introduces Solvent-Free Defoamer
for High Gloss Aqueous Coatings
Manufacturers of aqueous high-gloss and
wood coatings now have a new solvent-free, high-performance additive that eliminates foam without compromising surface
appearance or integrity: Troykyd D209W
from Troy Corporation. Highly compatible
Troykyd D209W offers excellent functionality in a broad range of aqueous systems, including high-gloss and wood coatings, both
clear and pigmented, as well as other end-use areas, including spray applied systems.
With a solvent-free composition, Troykyd
D209W is an excellent choice for environmentally ‘green’ coatings.
Troykyd D209W has shown equivalent
defoaming performance when compared
with the leading competitor products in fresh
aqueous paint samples, and superior defoaming performance in aged samples, which
translates into a significantly longer useful
service life for end-use paints and coatings.
Union Process Manufactures
S- 50 Batch Attritor for
Specialty Ceramics
Union Process, Inc. has built an S- 50 Batch
Attritor for a global customer who is using
the mill for a new process which involves
grinding specialty ceramics. As the product can have no metal contamination,
the 304 stainless steel tank is lined with
polyurethane, the agitator shaft is plastic-sleeved stainless steel, and the stainless
steel arms are zirconium oxide tipped and
polyurethane coated.
A Halar-coated product discharge
assembly has been included with a
plastic bar grid located on the bottom
of the tank.
As multiple shaft speeds were desired,
a variable frequency drive was provided.
The milling system included an air diaphragm pump for circulation to improve
grinding and to quickly discharge the mill.
Like all batch milling Attritors, the
S- 50 does not require any premixing.
Material can be directly fed into the
jacketed grinding tank. Temperature con-
trol can be maintained due to the use of
the jacketed tank. Wet grinding batch
Attritors are simple to operate, energy
efficient and require very little mainte-
nance. No special foundation is required.
New High Temperature
Ultra Nanoindentation
Tester from Anton Paar
Based on the technology of Anton Paar’s
Ultra Nanoindentation Tester, the High
Temperature Ultra Nanonindentation
Tester offers the highest resolution and
highest thermal stability Nanoindenter.
Active surface referencing technology
reduces thermal drift ( 10 nm/min at 400°C)
and our unique materials design allows for
negligible thermal expansion. The company
offers two new options: one up to 200 °C
and an option for 700 °C (under vacuum).
Key features include two independent
depth and load sensors and the highest
possible frame stiffness (> 108 N/m). An
integrated high vacuum chamber allows
testing at 5 x 10-7 mbar. Two ranges of
temperature are available with the same
Ultra Nanoindentation Tester.
Dymax Offers Plastic
Bonder with Moisture Cure
Dymax Corporation’s newest plastic
bonder cures with UV/Visible light and a
secondary ambient moisture-cure system
making it an ideal adhesive for applications
requiring shadow-area curing. Dual-Cure
3401 is specifically designed for rapid, high-strength bonding to hard-to-bond PC and
ABS as well as metal substrates. It exhibits
low shrinkage, resulting in less stress at the
bond line, and it cures fast – in 1 second –
enabling higher production rates. Dymax
3401 is low viscosity for better wetting and
is jetting compatible.
This versatile material is curable with
both broad-spectrum UV and narrow-spectrum 385 nm LED curing systems,
giving manufacturers options. Dual-Cure
3401 fluoresces blue under low-intensity
black light (365 nm) for easy visual inspection of the bond line.
Class 100 Cleanroom
Cabinet Oven From Grieve
No. 797 is a 260ºF (127ºC), electrically-heat-
ed, Class 100 cleanroom cabinet oven from
Grieve, currently used for drying coatings
onto printed circuit boards at the customer’s
facility. Workspace dimensions of this oven
measure 36” W x 36” D x 39” H. 20 k W
are installed in Incoloy-sheathed tubular el-
ements to heat the oven chamber, while a
1000 CFM, 1-1/2-HP recirculating blower
provides horizontal airflow to the workload.
This Grieve cleanroom cabinet oven fea-
tures 4” insulated walls, Type 304, 2B fin-
ish stainless steel interior with continuously
back-welded seams, exterior finished with
white epoxy paint, #4 brushed stainless steel
door cover and control panel face, 30” x
24” x 6” thick stainless steel high-tempera-
ture HEPA recirculating filter, plus all safety
equipment for handling flammable solvents,
including explosion-venting door hardware.
Controls on No. 797 include a digital indicating, programming temperature
controller and SCR power controller.
Custom Engineered Tanks
From Charles Ross and Son
Ross Custom Engineered Tanks are built
in ASME-code certified plants and can be
designed for virtually any use, application
or environment. These tanks can include
agitators, heating jackets or coils, insulation, thermowells, passivated surfaces
and special coatings or tank liners. Any
number of ports, manways and valves
may be specified on vessels as large as
100,000 gallons in capacity.
With state-of-the-art machining and
design capabilities, Ross accepts a wide
range of fabrication projects from simple
storage vessels to complex reactors and
tank farms, the company stated. Typical
materials of construction are carbon
steel, 304 and 316 stainless steel, Monel,
Hastelloy, Inconel, titanium and aluminum. Atmospheric, vacuum and high
pressure designs are routinely built in
various geometries. CW
