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 & water resistance Meets the requirements of WEEE & Ro HS This epoxy resin PX804C potting compound is a non-toxic general purpose flame retardant potting & encapsulating compound it is a safer alternativve to the popular PX700 & can be used for the same applications.PX804C has a long usable life & may be hot or cold cured. The system exhibits good surface finish high electrical strength good thermal conductivity low exotherm & low cure shrinkage. The semi-flexible nature allows thermal expansion without cured stress & this makes PX804C compatible with most circuit board components & materials over a wide temperature range. Adhesion is excellent to most plastics & substrates. The combination of properties & the ease of use of the material will lend itself to a wide range of applications. PX804C does not contain halogens or heavy metals & is available in 50g 250g 500g & 1kg form. The finish colour is black.
