With the release of the Sinteron 2010, Xenon xenon (zē`nŏn) [Gr.,=strange], gaseous chemical element; symbol Xe; at. no. 54; at. wt. 131.29; m.p. −111.9°C;; b.p. −107.1°C;; density 5.86 grams per liter at STP; valence usually 0. is delivering greater flexibility for sintering conductive Cu and Ag metallic inks, curing thin-film substrates and for solar avid surface modifications. The Sinteron 2010 allows for digitally programmable pulse widths. The ability to dial up just about any desired width makes the Sinteron 2010 extremely flexible and valuable to process development.
A number of attractive features are designed into this 19-inch rack-based stand-alone system. The pulse amplitude can be adjusted like the Sinteron 2000. The pulse width for the Sinteron 2010 is adjustable in increments of 5[micro]s in the range of l00ps to 2,000[micro]S. By having total control of the pulse amplitude and pulse width, the optical energy delivered by the system can be precisely controlled.
As the pulse profile is very linear at maximum amplitude, a relationship of l000J/ms can be assumed.
The Sinteron 2010 allows connection for either spiral or linear lamp housings. These can provide optical footprints of 19mm x 305mm (0.75 inches x 12 inches) or 127mm (5 inches) diameter areas. As Xenon Corporation manufactures lamps and lamp housings, other optical profiles are readily available.
The introduction of Sinteron 2010 is welcome news for those involved in photonic sintering of conductive inks for printed electronics in areas such as displays, smart cards, RFID (Radio Frequency IDentification) A data collection technology that uses electronic tags for storing data. The tag, also known as an "electronic label," "transponder" or "code plate," is made up of an RFID chip attached to an antenna. and solar applications.

Lubrizol Launches Solsperse 78000
The Lubrizol Corporation has introduced Solsperse 78000, a polymeric dispersant dis·per·sant
n. Chemistry
A liquid or gas added to a mixture to promote dispersion or to maintain dispersed particles in suspension. for energy-cured flexographic and offset inks in the printing ink industry.
Solsperse 78000 provides improved print gloss and optical density, superior mill base viscosity and increased color strength. Its launch adds a significant component to Lubrizol's range of performance products for the graphic arts industry.
Solsperse 78000 enhances the dispersion of high-performance pigments and carbon black when gloss and density are critical in the printing process. The improved dispersion provides optimum optical density, reduced haze and excellent print gloss.The new hyperdispersant also improves the viscosity characteristics of Newtonian (flexographic) inks, allowing for higher levels, of pigmentation pigmentation, name for the coloring matter found in certain plant and animal cells and for the color produced thereby. Pigmentation occurs in nearly all living organisms. . Viscositv remains nearly constant across a typical shear rate.
Solsperse 78000 is suitable for dispersing difficult to stabilize high performance organic pigments -- including isoindolinone yellow, quinacridone Quinacridone is a red powder. It is an organic compound with the molecular formula C20H12N2O2. It is used as a pigment; analogs bearing this motif are known as quinacridones.

Further, it is the appropriate choice for the right mix of viscosity and color development for higher pigmentation in finer-line printing.

BASF BASF Bar Association of San Francisco (since 1872; San Francisco, California)
BASF Badische Anilin und Soda Fabrik (German chemical products company)
BASF Builders Association of South Florida Introduces Joncryl 633 Emulsion Polymer
BASF has introduced Joncryl 633 emulsion polymer, a cost-effective ink vehicle that improves opacity of inks and requires less titanium dioxide. Joncryl 633 emulsion polymer can help ink formulators achieve high levels of color intensity and opacity in inks used on natural kraft substrates, such as brown box corrugated containers and paper bags.
Tests conducted in BASF laboratories with Joncryl 633 demonstrate higher opacity and better color performance than other standard opaque emulsion polymers.
This is a benefit that will appeal to brand owners who are concerned about color consistency, since kraft substrates can vary in color based on the source of the fiber.
Tests conducted in BASF laboratories also demonstrate that Joncryl 633 improves the rub resistance and water resistance of inks compared to standard opaque emulsion polymers.
