New Preeflow® eco-SPRAY for High-viscosity UV Adhesives: ViscoTec

Published on 2017-02-16. Author : SpecialChem

Preeflow

The new preeflow® eco-SPRAY precise volume dispenser from ViscoTec is the ideal solution for even and fast application of Panacol maskings and conformal coatings. The new technology yields perfect results with exceptional edge sharpness whether spraying low- or high-viscosity UV adhesives.

Spraying Adhesives - A Child's Play

Spraying high-viscosity adhesives from Panacol onto large surfaces at more than 10,000 mPa becomes child’s play with the eco-SPRAY from ViscoTec: the new dispenser makes short work even of highly viscous and stable materials, such as Panacol’s liquid seal Vitralit® FIPG 60102 or masking compound Vitralit® MASK 20102. The purely volumetric dosing of the eco-SPRAY system uses the endless piston principle to precisely meter and apply exact amounts regardless of their viscosity and supply pressure.

eco-SPRAY is Intuitive


To achieve the required layer thickness, the applied amount can be changed simply by changing the air pressure, the adhesive volume, the distance to the substrate or the speed of application. The eco-SPRAY is intuitive in use and can be adapted to different materials and dosing processes with a range of supplied needle diameters and air caps.

Capable of handling viscous adhesives, the eco-SPRAY has also proven suitable for spraying and vaporizing low-viscosity conformal coatings. The two products used here were Vitralit® 2004 F and Vitralit® 2007 F – both dual-curing epoxy resin based adhesives. With the eco-SPRAY, both of these adhesives can be applied as surface coatings with high edge sharpness and cured in a continuous process with UV flood lamp, for example from Hönle’s UVAPRINT range. Here, the arc length can be ideally adapted to the PCB’s width.
