Technotherm 3000 - Optimum conductivity, hardly any voltage losses, THE ideal embedding resin for electrolytic polishing. Technotherm 3000 is based on a graphite filler and thus guarantees optimum conductivity with very low shrinkage. Technotherm 3000 is the conductive material of the Technotherm line. Technotherm 3000 is used wherever high conductivity is required (e.g. in scanning electron microscopes). When testing in the SEM, Technotherm 3000 virtually eliminates voltage losses (less than 0.5%). Technotherm 3000 is also the ideal embedding resin for electrolytic polishing
