Heraeus Kulzer has been a leading developer and manufacturer of high quality polymer products for both the medical and technology sectors for many decades. Resins used in medical and materials technology must be of high quality, easy to use and have dependable properties to ensure their successful employment. Heraeus Kulzer’s polymers fulfil the highest requirements and are used as embedding resins for materials testing or as auxiliary materials in production techniques. They therefore occupy an important place in the everyday activities of modern laboratories and in manufacturing processes. The particular fields in which these polymers are applied determine the specific characteristics required of our products.

Heraeus Kulzer’s product portfolio, including its range of sophisticated polymers, has been setting standards with regard to quality and the efficient processing methods employed to work with these materials.

The umbrella brand name “Technovit”, developed many years ago, has come to represent the expertise upon which the development, manufacture and applications technologies of a broad range of polymer products employing a variety of technologies are based.

The main emphasis of these products is their application in materials testing. The properties that are especially demanded are gapless embedding, transparency, time efficiency and easy application, as well as the highest possible degree of impression precision and form stability. Heraeus Kulzer fulfils all these requirements with its comprehensive Technovit programme.

For metallographic applications the following embedding resins are recomended

Technovit 7100

technovit-7100Technovit 7100

Technovit 7100 is an embedding resin system based on 2-hydroxyethyl-methacrylate (GMA). Glycol methacrylate is used in the field of histology to embed tissues (medicine, botany, zoology and industry) for light-microscopy studies.

The polymerisation of GMA is initiated by means of a barbituric acid derivative in combination with chloride ions and benzoyl peroxide. The catalyst does not contain aromatic amines, which can be regarded as an advantage compared with already existing systems which are based on peroxide/aromatic amines. The system provides clear resin blocks from which 1 to 2µ sections are obtained.

Technovit 8100

technovit-8100Technovit 8100

Technovit 8100 is a new combination of a less toxic and nearly odourless plasticiser and a water miscible resin. Technovit 8100 can be used for the embedding of all kinds of medical and botanical tissues, particularly immunohistochemistry examinations of lymphatic tissue (lymphatic nodules, thymus, spleen, tonsils), liver-kidney-bone biopsies.

Technovit 9100 NEW

Technovit 4000 and 4004

clip_image015

Technovit 4000 is a fast polymerising cold curing three-component resin based on modified polyester supplied as powder, syrup I and syrup II.

Technovit 4000 is suitable for the gap-free embedding of specimens: that are difficult to embed because of their shape or coating that cannot be exposed to high temperature or pressure which require(s) fast and accurate testing which the embedding material must be abrasion-resistant.

Technovit 4004 is a fast polymerising cold curing two-component resin supplied as powder and liquid.

Technovit 4004 is suitable for embedding specimens which require a transparent embedding for fast routine work.

It is advisable to cure this resin in the Technomat, in order to obtain a bubble-free and thus highly transparent specimen.

Technotherm

clip_image024Technotherm Heraeus Kulzer

With the Technotherm Heraeus Kulzer offers state-of-the-art warm embedding material which meets the highest demands. To offer a clear product range we have first focused on three different products.

Technotherm 1000

clip_image025Technotherm 1000

Technotherm 1000 is an inorganically filled yellow-brown embedding resin. It attains a high degree of hardness and good edge definition. Technotherm 1000 has optimal machining properties and is resistant to all customary etching and cleaning agents used in the laboratory.

Technotherm 2000
Technotherm 2000 is a inorganically filled glass-fibre-reinforced resin, in a white/grey colour. Technotherm 2000 attains a high degree of edge definition for gap-free embedding. Because of its outstanding melt properties during the embedding procedure, Technotherm 2000 penetrates deeply into porous surfaces or specimen undercuts. It is THE universal warm embedding resin. Technotherm 2000 is resistant to all customary etching and cleaning agents used in the laboratory.

Technotherm 3000

Technotherm 3000 is the electrically conductive resin in the Technotherm line. The graphite-filled resin has outstanding electronically conductive properties. Technotherm 3000 is employed for the embedding of specimen to be examined under the SEM (scanning electron microscope). In the SEM studies, voltage losses are almost eliminated with Technotherm (less than 0.5%).

Technotherm resins cure at 160 – 180 °C and 80 – 90 bar in 11 – 15 minutes, depending on the diameter of the embedding cylinder in the press.

Technovit 2000 LC

clip_image026Technovit 2000 LC

Technovit 2000 LC is a one-component resin based on monofunctional and difunctional methacrylate. Technovit 2000 LC polymerises under blue light in the Technotray CU unit. Technovit 2000 LC was developed especially for the testing or preparation of sensitive materials and micro-parts. The main fields of application are semiconductors, microelectronics, medical instrumentation, optoelectronics, and microsystemtechnique.

Its most important advantages are:

Almost unlimited processing time without time constraints

No danger of premature curing

Material can be cured in several layers

Very good transparency, extremely low gap formation

Bubble-free, odour-free

The comparatively low polymerisation temperature is about 90°C and can be reduced further if the embedding is carried out in several layers.

Use of the Technovit 2000 LC covering varnish is recommended to prevent a “dispersion layer” (smear layer on the surface).

Polymerisation is carried out in the Technotray ® CU device.

Technovit 3040

clip_image029Technovit 3040

Technovit 3040 is a fast-curing cold polymerising resin based methyl methacrylate supplied as powder and liquid.

Technovit 3040 is used as an auxiliary agent in indirect surface testing in mould and tool-making, as well as in measuring technology.

Technovit 3040 is a special resin for preparing replicas and mouldings. The replica accuracy is 1 micron.

With Technovit the condition of surfaces can be checked indirectly the condition of surfaces can be preserved and recorded negative moulds – e.g. of silicone or plaster – can be filled up, to produce obtain a positive of a possible defective zones positives can be produced by double reproduction (Technovit impression of Technovit).

Grinding/Lapping Discs – Grinding/Lapping Foils

clip_image033Grinding/Lapping Discs

Grinding/Lapping Discs The patented New Lam Lapping Discs and Lapping Foils consist of a composite of synthetic resin-bonded metal powder mix with cylindrical, but softer, metal powder inclusions.

The resulting special surface structure causes the diamond grains to be jammed more or less strongly on the disc during the lapping, and thus changes their rolling or cutting behaviour.

clip_image035Grinding/Lapping Foils

Grinding/Lapping Foils If the specimen are small, self-adhesive lapping foils applied to a carrier disc can also be used.

The quality of the results is absolutely identical. Lapping discs and lapping sheets can be used on all modern grinding machines.
