Lucy, Try Enthone (203-934-8611) or Humi-Seal. Enthone frequently advertises their VOC-free conformal coatings in publications such as Surface Mount Technology and Circuits Assembly. Humi-Seal is the "Grandfather" of conformal coatings. Greg Kilinski Acuson Corp.

Try Dow Corning, Grace Specialty Polymers, or Shin-Etsu for silicones or Specialty Coating Systems for Paralene.

Some of my require- ments are as follows: -high dielectric strength -good adhesion to flux residues -UL and/or Mil-Spec approval -able to withstand high temperature applications (~130 C) for extended periods -fast cure -easy to apply -easy to rework -moisture resistant -solvent-free -no outgassing -volatile organic compound-free (VOC-free) -relatively same thermal expansion coefficient as PCB panel Lucy Rojao [log in to unmask] phone: (416) 448-5866 fax: (416) 448-4736 *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
