About this product

Overview

  • A good alternative to PX700K
  • High electrical insulating characteristics
  • Non-toxic

Product overview

• A good alternative to PX700K• High electrical insulating characteristics• Non-toxic• Good thermal conductivity• Low shrinkage• High adhesion• Flame retardant to UL94-V0 @ 3mm• Good chemical and water resistance• Meets the requirements of WEEE and RoHS

This epoxy resin PX804C potting compound is a non-toxic general purpose flame retardant potting and encapsulating compound, it is a safer alternativve to the popular PX700 and can be used for the same applications.PX804C has a long usable life and may be hot or cold cured. The system exhibits good surface finish, high electrical strength, good thermal conductivity, low exotherm and low cure shrinkage. The semi-flexible nature allows thermal expansion without cured stress and this makes PX804C compatible with most circuit board components and materials over a wide temperature range. Adhesion is excellent to most plastics and substrates. The combination of properties and the ease of use of the material will lend itself to a wide range of applications. PX804C does not contain halogens or heavy metals. The finish colour is black.
