Technovit® 3040
For dimensionally stable impressions
High impression accuracy, dimensionally stable, easy to remove, good evaluability. Technovit 3040 is THE classic for indirect surface inspection.
The flexibility in mixing the components ensures both the pouring of a form and the impression in hard-to-reach places, verticals as well as working overhead.
Benefits
- Impression accuracy 1 μm
- dimensionally stable and easily removable
- variable mixing ratio possible
- Stabilization for mechanical processing
- Impressions can be evaluated with probes or non-contact measuring methods
Product details
The 2-component resin consists of a powder and a liquid component. Depending on the requirements, the material can be mixed in a ratio of 1:1 to 3:1 (powder/liquid). The standard mixing ratio of 2:1 can be poured for approx. 2 minutes and then is malleable for approx. 30 seconds. The curing time is 9–12 minutes from the start of mixing.
Practical tip
- to ensure dimensional accuracy, keep the impression surfaces as small as possible (for larger volumes, work in multiple layers)
- the modelling of a handle facilitates the removal of the impression from the original
- Impressions should have a minimum thickness of 5 mm in order to avoid slight distortion during removal.
- Impressions of undercuts cannot be taken!
- To take impressions on verticals or overhead, we recommended pouring Technovit 3040 on a PE film and pressing it on the surface to be cast.
