RHEOFINISH 225 DWater based chemical release agent

DescriptionA ready to use water based, safe, effective releaseagent which is friendly to the environment.RHEOFINISH 225 D is applied to mould andshutter faces prior to casting concrete in order toachieve a clean release. After removal of theformwork, the resultant concrete has a smooth,hard, uniform finish, with reduced incidence ofblow holes. RHEOFINISH 225 D can be appliedto the formwork by spray in the form of a lightuniform mist coating.

Primary usesRHEOFINISH 225 D is formulated for applicationto plywood, timber, steel and plastic facedformwork and moulds, prior to casting concrete,to ensure a clean release.

PackagingRHEOFINISH 225 D is available in 20 and 210litre drums. Bulk deliveries available upon request.

*Typical propertiesColour Milky liquidSG finished product 0.971 at 25CChloride content: Nil

CompositionA chemically active release agent blended withwater.

Directions for useApply before the first casting and thereafter re-apply immediately after stripping and cleaning themould.

Lightweight horticultural sprayers are ideal asRHEOFINISH 225 D is finely atomised to give auniform coating. Excessive application should beavoided.Alternatively, application may be made by a finehaired brush, only a very thin coating should bemade and any excess removed.

If after the first application, the RHEOFINISH 225D is completely absorbed into new timber orplywood, a further application should be madebefore filling the moulds or formwork.

ActionRHEOFINISH 225 D reacts chemically withcement to impart excellent release properties totreated surfaces. Concrete cast against surfacescoated with RHEOFINISH 225 D exhibit asmooth, hard, uniform finish.

RHEOFINISH 225 D has no negative effect onthe properties of concrete nor will it impair theadhesion of subsequent surface treatments whenapplied at the recommended coverage rates.

CoverageThe coverage rate for RHEOFINISH 225 D isbetween 30 to 40m/litre when spray applieddepending on smoothness and porosity of theformwork used. Coverage is considerablyenhanced on marine ply and steel faced forms.

Note:Progressively better results are obtained onplywood and timber moulds as they becomeimpregnated and the operatives becomeaccustomed to working with the release agent.RHEOFINISH 225 D in general, may be used overtimber moulds etc., which have been treated withother mould oils, providing excess has beenremoved.

Equipment careRHEOFINISH 225 D may usually be left in sprayguns or sprayers without detriment, but withcertain types, there may be some softening ofrubber seals with prolonged contact.
