Chemical shutter/Mould release agent
durastrip is a milky white emulsion and is a semi environmentally friendly mould release agent based on a combination of water and solvent.
Uses
durastrip can be used as a release agent for steel, plywood, timber and plastic formwork moulds prior to casting concrete.
durastrip provides a water repellant film that protects both steel and timber formwork.
Advantages
- Reduced solvent reduces risk to the environment. durastrip is a specially formulated emulsion consisting of water as well as solvent to give optimum results.
- It is semi water based and is therefore safe and clean.
- Excellent concrete finish is achieved that exhibits smooth, hard, uniform finishes.
- durastrip has no negative effect on concrete properties
- durastrip does not impair the adhesion of subsequent surface treatments when applied at the recommended coverage rates.
Physical Properties
Form | Liquid Emulsion |
Colour | Milky |
Density | 0.95 – 1.05 |
Specification compliance: Exceed the needs of release agent as described by ASTM & BS
Surface Preparation
All surfaces must be clean, dry and free of all loose materials. Steel surfaces must be free of rust or mill scale. If extensive re-use of timber moulds is envisaged it is advisable to protect all new surfaces with abecote® 320, which protects timber from alkali attack.
See relevant data sheet.
Coverage
Typically: 30 – 40m2 per liter.
The coverage is dependent on the substrate roughness and porosity. A trial is highly recommended to determine exact quantities.
Mixing
durastrip is a ready to use formulation and does not require any mixing. It should however be stirred prior to use.
Application
Minimum application temperature: 5°C.
durastrip must be applied at the recommended spread rate and any excess must be removed. durastrip should be applied by brush, sponge roller, or conventional mould oil sprayer. durastrip should be applied in one continuous even film. All nonabsorbent surfaces require only a single application.
NOTE:
New, unsealed timber surfaces should be re-coated if a delay period in excess of 48 hours occurs. After use, formwork should be brushed and treated with durastrip as previously described. Remove durastrip completely for purposes of repair or for resealing with abecote® 320.
See the relevant datasheet.
