ڤيتوبوند اي بي 430

عميل ربط إيبوكسي خالٍ من المذيبات.

Vetobond EB430 is based on solvent-free epoxy resins. It contains pigments and fine fillers and is supplied as a twocomponent and pre-weighed product that’s ready to use and mix on-site. Vetobond EB430 is suitable for external and internal applications (on both horizontal and vertical surfaces) wherever mortar or concrete can be supported by a type of formwork. The long ‘open’ life makes it suitable for formwork or where additional steel reinforcement is needed. The product is ideal for roads, bridges, pavements, loading bays, factories, and bonded or granolithic floor toppings.

الاستخدامات

  • To connect existing concrete to new one.
  • To eliminate cold joints as a result of casting stops.
  • As a primer for bonding cementitious repair materials (Vetorep range of products).
  • To bond cementitious screeds to concrete substrates.

المزايا

  • Adhesive bond to concrete will always exceed the tensile strength of the host concrete.
  • Suitable for use on damp and dry concrete.
  • Odorless and non-flammable (remains tacky for 48 hours at 22°C).
  • Resistant to hydrolysis (making it ideal for external and internal applications).
  • High mechanical properties.
  • Excellent bond to concrete, masonry, stonework, plaster, and cement boards.

تعليمات الاستخدام

Clean all surfaces and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits, or algae. Roughen the surfaces, remove any laitance and expose aggregate by light scabbling or grit-blasting. Remove oil and grease deposits by steam cleaning, detergent scrubbing, or using a proprietary degreaser.

A pull-off test should then assess the effectiveness of decontamination and the soundness of the substrate. Any steel reinforcement and formwork should be prepared, cut to size and shape, and made ready for assembly before mixing begins.

The Vetobond EB430 mix must be mixed thoroughly.

To begin, stir the ‘hardener’ and ‘base’ components separately before mixing them together (to disperse any settling material). Pour the entire content of the ‘hardener’ tin into the ‘base’ tin. Mix the two materials thoroughly using a suitable slow-speed drill and mixing paddle for 2 minutes until a fully uniform color can be seen. Scrap the sides of the tin, and continue mixing for another minute. Slowly add the Reducer part and mix for 3 additional minutes.

To facilitate mixing and application at temperatures below 22°C, the separate components should be warmed in hot water up to a maximum temperature of 25°C before beginning to mix. If heated to 25°C, the subsequently mixed material will need to be used more speedily as the pot-life will be reduced to 4 hours. Alternatively, Store the material in an environment heated to 22°C and take the stock directly from the store immediately before use

Apply Vetobond EB430 as soon as the mixing process is completed. Brush Vetobond EB430 or spray it onto the prepared surfaces. The new concrete or screed may be applied to the coated substrate in up to 24 hours after the application (at 22°C or up to 12 hours at 30°C, or between 8 to 10 hours at 35°C). However, you should leave the coated substrate for 1 hour before placing the new concrete or screed.

Your goal is to achieve an unbroken coating if you’re using Vetobond EB430 as part of a repair system to form a substrate/repair barrier. Apply one coat and allow it to turn to gel. Apply a second coat and use it as the bonding coat.

In some situations (e.g., sprayed concrete repairs), it may be advantageous to scatter dust-free sharp sand over this coat and leave it to harden. As soon as the Vetobond EB430 has been applied, any required steel reinforcement and/or formwork should be elected and fixed securely in place.

Remove Vetobond EB430 from tools, equipment, and mixers with Vetonit Solvent 1 immediately after use. Hardened material can only be removed mechanically
