PCB Conformal Coatings of UV Cure Silicone

Novagard Solutions announces UL746E approval on NOVAGARD UV™ silicone conformal coating product. NOVAGARD UV 800-260 is the only UV curable silicone conformal coating to have met the rigorous testing and approval of UL746E. View UL Listing

Essential for protecting electronic circuitry and significantly extending the service life of printed circuit boards, conformal coatings are an integral component of the entire sub-assembly. Eliminating moisture and contamination is a key element for protecting sensitive electronics. Silicone conformal coatings provide an effective barrier in even the most severe services conditions. NOVAGARD® Silicones UV cured conformal coatings maintain all of the enhanced performance characteristics of conventional silicone based materials with processing speeds unmatched by other technologies. The unique and patented UV-cure silicone chemistry found in the NOVAGARD conformal coatings provides dual-cure capabilities where a secondary moisture cure effectively eliminates any problems associated with shadowing on complex parts.

Ultra Violet Systems

  • Exceptionally fast UV cure ; Room temperature curing
  • Minimal UV energy requirements; Little or no heat generated so parts remain cool
  • Process or package a part immediately; No racking
  • Cure up to ¼” (6.3 mm) of material 10 times faster than other well known brands
  • No oxygen inhibition ; No corrosive by-products
  • Excellent dielectric properties

UV/Moisture Dual Cure

  • Cures upon exposure to either a UV light source or atmospheric moisture
  • Dual cure continues to build strength and adhesion after the initial UV cure cycle
  • Moisture cure eliminates shadow effects on complex parts
  • Neutral, non-corrosive secondary cure system will not harm sensitive components
  • Excellent dielectric properties
  • Solvent Free / 100% solids – no VOC’s to handle or report
