Chemical Shutter/Mould Release Agent

dura.®strip is a milky white emulsion and is a semi environmentally friendly mould release agent based on a combination of water and solvent.

Uses

dura.®strip can be used as a release agent for steel, plywood, timber and plastic formwork moulds prior to casting concrete.

dura.®strip provides a water repellant film that protects both steel and timber formwork.

Advantages
  • Reduced solvent reduces risk to the environment. dura.®strip 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. 
  • dura.®strip has no negative effect on concrete properties 
  • dura.®strip 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 abe.®cote 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

dura.®strip 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. 

dura.®strip must be applied at the recommended spread rate and any excess must be removed. dura.®strip should be applied by brush, sponge roller or conventional mould oil sprayer. dura.®strip 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 dura.®strip as previously described. Remove dura.®strip completely for purposes of repair or for resealing with abe.®cote 320

See relevant data sheet.
