Electronic printed circuit boards based on CEM3 laminates provide a major market for wet formed mat (veil). It offers better dimensional stability than phenolic paper base laminates and lower processing costs than circuit boards reinforced with woven glass fabric. Wet formed mats are available in various weights and widths to suit all the manufacturing processes and are compatible with epoxy resin systems. High consistency, superior fiber distribution and surface smoothness make Owens Corning non-wovens a perfect product for this application.
