TEGO® RC Silicones News
State of the art pilot facility in Richmond
The Richmond Business & Innovation Technical Center offers a state of the art pilot facility for trials with our customers and Partners.
Our Faustel coating line includes a three-roll offset gravure system, Enercon Corona Treater and an Eltosch Inert chamber with arc lamps. This line is available for customer trials, product development or training with our TEGO® RC silicones upon request.
The three-roll, gravure coating head has a coating width of 610 mm (24 inches). All rolls can be driven independently. The three-roll coater allows for coat weights as low as 0.5 g/m2 up to 2.0 g/m². The enclosed doctor blade system is a Faustel design with center mounted doctor blade. During trials, line speeds can be varied from 75 - 800 feet/min. (25 – 250 m/min.). All substrates whether paper or plastic films can be handled with a minimum film thickness of one mil (25 microns). The corona pre-treatment (necessary for good adhesion of the silicone to the substrate) is applied in-line.
Max. silicone width: 23.375” (59.37 cm)
Max. substrate width: 24” (60 cm)
Max. diameter roll: 60cm
Core diameter: 3 or 6” (76 or 152 mm)
Our Three-Roll System Speed
Gravure roll Speed 20 to 50 % of line speed
Chrome plated roll 220 QCH CtWt 1.0 to 1.4 gsm, 260 QCH CtWt 0.8 to 1.06
Application roll Speed 90 to 110 % of line speed, standard 98.5%, EPDM covered steel roll, hardness 60 Shore A

The UV system was built by Eltosch, Hamburg (Germany). It offers two arc UV lamps of 200 W/cm with adjustable power output from 40 – 400 W/cm. The nitrogen inerted curing chamber maintains oxygen content below 50 ppm which is necessary for good curing of our free radical technology. The nitrogen consumption at 250 m/min. is as low as 75 m³/h.
