Spray release agent Doka-OptiX

for the construction industryfor formwork surfacesanti-adhesive

Overview
Doka offers release agents for both smooth and absorbent formwork surfaces. They provide effective separation and help achieve attractive concrete finishes.

Doka-OptiX
The release-agent specially designed for smooth form-facings

• easy to apply – simply sprayed on with no need to wipe off excess
• produces bright, low-porosity concrete faces due to the emulsion chemistry
• "ready" indicator prevents incorrect use – pouring can begin once the white colour has disappeared
• can be sprayed in light rain and at temperatures down to -4° C
• ready for use up to 14 days after application
• biodegradable formulation
• GISCODE BTM 01 - fulfils DGNB quality levels 1 to 4*
• supports attainment of DGNB Platinum certification

Doka-Trenn
The universal release-agent for absorbent formwork surfaces

• excellent separating effect makes formwork easy to detach
• highly cost-efficient: can be used very sparingly (up to 100 m²/l depending on substrate)
• good creepability leaves a protective coating on equipment and formwork
• frost resistant for year-round use
• does not impair adhesion of subsequent coatings or smoothing layers on concrete
• GISCODE BTM 20 - fulfils DGNB quality level 1*

Notes
The GISCODE is a classification system for health and safety assessment by BG-BAU, which assigns building products to comparable hazard classes. In relation to DGNB certification: the lower the GISCODE, the higher the possible quality level.

Availability and packaging
Doka release agents are available in practical containers in various sizes suitable for site use. Visual comparisons illustrate improved concrete surface quality with Doka-OptiX versus petroleum-based release agents.
