Doka-OptiX
The release-agent specially designed for smooth form-facings
- easy to apply – is simply sprayed on with no need to wipe off any excess
- bright, low-pore concrete faces, due to the chemical composition of the emulsion
- 'ready' indicator rules out incorrect use – pouring can begin as soon as the white colour has disappeared
- can also be sprayed on in light rain and at temperatures of down to -4° C
- ready for use for up to 14 days after being applied
- eco-friendly, as it is bio-degradable
- GISCODE BTM 01 - fulfils quality levels 1 to 4* for DGNB certification
Doka-Trenn
The universal release-agent for absorbent formwork surfaces
- excellent separating effect makes formwork easy to detach
- highly cost-efficient, as it can be used very sparingly (up to 100 m²/l)
- excellent creepability leaves a protective coating on construction equipment and formwork
- frost resistant, so can be used all year round
- does not impair adhesion of subsequent coats or smoothing-layers on the concrete
- GISCODE BTM 20 - fulfils quality level 1* for DGNB certification
Assignment of the GISCODE classifictaion to the DGNB quality levels

The following applies to DGNB certification in connection with the classification of concrete release agents using GISCODE: the lower the GISCODE, the higher the possible quality level.
