Product details

Robnor Resins PX804C Epoxy Resin 250g

• 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.

Once opened (let's say for use in one project), can the bags be closed again (for later use) or does the whole bag have to be used once opened?

Asked by: Tarvoc
sorry no The 2 parts of the mix are stored in the same sealed plastic blister pack, once the separation clip is removed and the two halves mixed then the setting reaction has begun. It should be used quickly after that point as even if you do not open the pack the mixture will eventually solidify.
