Solvent-free epoxy bonding agent to bond old to new concrete
Vetobond EB430 is based on solvent-free epoxy resins containing pigments and fine fillers. It is supplied as a two-component material in pre-weighed quantities, ready for on-site mixing and use. The product is used in external and internal applications on horizontal surfaces or on vertical surfaces where mortar or concrete can be supported by formwork. The long ‘open’ life makes it suitable for formwork or where additional steel reinforcement is fitted. The product is ideal for roads, bridges, pavements, loading bays, and factories, and bonded or granolithic floor toppings.
ASTM C 881/881M-13 (Standard Specification for Epoxy-Resin-Base Bonding Systems for Concrete) as Type I, II, III, IV & V - Grade 3 class B & C
Vetobond EB430 is supplied in 5 Liters Kit.
Coverage: 5-8 m2/Liter.
Stated consumption data is for general guidance. Actual consumption depends on the nature of substrate, method of application, and wastage.
The original sealed container of Vetobond EB430 has a shelf life of 12 months, provided it is stored clear of ground in a dry, shaded place below 35ºC.
Vetobond EB430 has an overlay time of 24 hours at 22ºC, 12 hours at 30ºC, or 8 to 10 hours at 35ºC, making it more suitable for use where additional steel reinforcement and formwork has to be fitted or where temperatures are high.
Apply Vetobond EB430 as soon as the mixing process completes. Brush Vetobond EB430 or spray it to the prepared surfaces. The new concrete or screed may be applied to the coated substrate up to 24 hours after application at 22ºC or up to 12 hours at 30ºC, or between 8 to 10 hours at 35ºC. However, leave the coated substrate for one hour before placing the new concrete or screed. Take care to achieve an unbroken coating, where Vetobond EB430 is used as part of a repair system to form a substrate/repair barrier. Apply one coat and allow 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.
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 the use of 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 commences.
Ensure mixing Vetobond EB430 thoroughly. Stire the ‘hardener’ and ‘base’ components separately before mixing to disperse any settlement. 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 obtaining a fully uniform color. Scrap the sides of the tin, and continue mixing for a further 1 minute. Slowly add the Reducer part and mix for 3 minutes.
To facilitate mixing and application at temperatures below 22ºC, the separate components should be warmed in hot water up to a maximum temperature of 25ºC before beginning to mix. If heated to 25ºC, 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 22ºC and remove it immediately before use.
Vetobond EB430 should not come in contact with skin or eyes or be swallowed. Ensure adequate ventilation and avoid inhalation of vapors. Some people are sensitive to resins, gardeners, and solvents. Wear suitable protective clothing, gloves, and eye protection. Suppose working in confined areas, use suitable respiratory protective equipment.
The use of barrier creams provides additional skin protection.
In case of contact with skin, remove immediately with resin-removing cream followed by washing with soap and water.
Do not use solvent. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately – do not induce vomiting.
Vetobond EB430 is non-flammable.
