1. Surface Preparation

  • To obtain an optimum adhesion, the surface must be clean, degreased and dust-free. When applying to metal, first remove the milling surface or the oxidised skin.

2. Mixing

  • Prior to mixing, stir the components separately to eliminate sediments.
  • Add B-component completely to A-component. Mix thoroughly with an electric mixer (3-4 min, max 600 rpm) until an uniform grey colour is obtained.
  • Avoid mixing air into the mixture.
  • The mixing ratio A/B is 3:1.

3. Application

  • Remove the water before application of the adhesive.
  • Apply with a spatula, trowel or by hand (wear suitable rubber gloves).
  • Apply Multitek Adhesive SDW directly to the surface.
  • Perfect application temperature is between 10° and 20°C.

4. Cleaning

  • Mixing and application equipment should be cleaned immediately with Washing Agent Eco. Remove hardened material mechanically.


Multitek Adhesive SDW: 1.8kg / m2 per mm thickness


Multitek Adhesiv SDW should be stored in the original packaging in a dry area. Storage temperature must be between 5°C and 30°C. Once a pail has been opened, the useful life of the material is greatly reduced and should be used as quickly as possible. Shelf life: 2 years.

Health and Safety

Multitek Adhesive A-component is classified as irritating.
Multitek Adhesive B-component is classified as corrosive.

Multitek Adhesive SDW is a product based on epoxy and can therefore cause irritations to skin and mucous membranes which should be protected during application.
