copolymer resin with a high level of inertness. The wetted surfaces
of the stainless steel vessel, cover and charge ports are all PFA-coated as well to prevent metal ion contamination. Designed for a
high-purity electronic application, this vacuum-capable inert mixer
includes a recirculation filter system. Operators control and monitor the agitators, recirculation pump, recipe menu, temperature,
vacuum level and data acquisition from a 10” color touch screen.
Ross offers a number of coating options such as aluminum
oxide, chromium oxide, polyvinylidene fluoride (PVDF), nylon
and tungsten carbide. Other surface treatments include electropolishing, boronizing and hard chrome plating. The company also
manufactures storage tanks, pressure vessels and reactors that can
be lined with any appropriate chemical-resistant coating.
Celeritas unveils high-performance grades of
organophilic clays for paints and coatings
Celeritas Chemicals has introduced three new high-performance
grades of organophilic clays specifically designed for the paint
and coatings industry. CELCHEM 31743-09, 31744-09 and
31745-09 are organoclays for solvent-based systems of low to
medium polarity. According to the company, they offer the following advantages for paint and coatings formulators: high
gelling efficiency over low to medium polarity organic liq-uids,easy incorporation and consistent in rheology and
thixotropy development and excellent sag resistance.
Union Process Circulation Attritor used for
production scale biomass project pilot plant
Union Process, Inc.’s Q- 25 Circulation Attritor is being used in a
pilot plant environment to validate a production process for
waste material to be utilized as a break-though “green” alternative energy resource.
For customers who already have an existing system
with a premixing or holding tank, the high flow-rate inherent in the Circulation Attritor is an ideal option, according to the company. With an appropriate sized
pumping system, a relatively small “Q” Attritor can efficiently
grind material from a much larger process tank which means
value-added benefits including maintenance and cost savings.
Circulation Attritors are ideal for uninterrupted, large-scale
production. They deliver faster grinding with the desired narrow
particle size distribution and are simple and safe to operate.
Ashland launches Natrosol Performax HEC
paint thickening technology
Ashland Specialty Ingredients will introduce Natrosol Performax
hydroxyethylcellulose, a breakthrough paint thickening technology, at the ChinaCoat 2012. Natrosol Performax is comprised of
a range of hydroxyethylcellulose thickeners that delivers process
flexibility and quality control to paint manufacturers. This allows manufacturers to add HEC in dry form at any point of the
manufacturing process, eliminating extra process steps like the
preparation of pre-slurries or dissolutions of HEC, saving operational costs, according to the company.
Natrosol Performax thickeners enhance paint quality and preserve critical performance characteristics, such as efficient thickening, stability, color compatibility and sag resistance. CW
