DEZOSIVE 4000
TWO COMPONENTS, SOLVENT FREE INJECTION ADHESIVE
DEZOSIVE 4000 is a two-components, solvent-free injection adhesive specially formulated based on high strength modified epoxy resin and special hardeners. This product is designed in low, medium and high viscosity ranges to allow injection in different parts of cracks. This product is able to be used in grouting of either wet, dry and water-filled cracks to result in a filled cracks and fully restored concrete. It conforms to ASTM C881 and EN 1504-5.
FIELD OF APPLICATION
- Pressure injection of cracks in structural concrete and masonry
- Able to be injected in any condition of cracks in process of structural repairs
- Seals concrete from water absorption, chloride-ion intrusion and chemical attack
- Prolongs life of cracked concrete
CHARACTERSTICS/ADVANTAGES
- Excellent bond to wet, water filled and dry concrete
- Different viscosity ranges for excellent penetration into existing cracks
- Injectable by a single component either manual or automated pumps
- Solvent free
- Resistant to wide range of chemicals
SUBSTRATE PREPARATION
Substrates must be sound, clean, free from oil and grease, old coatings, surface treatments, etc. Concrete, mortar and stone should be thoroughly prepared by mechanical means such as grinding, chiseling, etc. Cracks must be cleaned to remove dust by using compressed air.
In case of Inaccessible cracks, use ETCHING SOLUTION twice for 15 minutes. After each time, rinse thoroughly with water for 15 minutes.
EXTENSION OF USAGE
Depending on the Geometrical Scale of Section to be Injected, the appropriate amount and type of products should be considered.
APPLICATION
DEZOSIVE 4000 is supplied in two containers as a unit. Always mix a complete unit in the proportion supplied. Once the unit has been mixed it must be used within the working Pot life specified. 1-Agitate Part A and B separately with a power agitator.
2-Combine entire contents of curing agent (part B) with base (part A) and mix thoroughly with power agitator.
3-Mix thoroughly for at least three minutes, scraping the container bottom and side to assure complete mixing. There is no induction or waiting time required after mixing before injection.
Mixed DEZOSIVE 4000 can be injected under pressure into the cracks using a single component injection pump, or a high pressure hand pump. Injection ports (packers) are set at appropriate intervals next to the crack and the crack between the injection ports (packers) sealed with MORTAR EPOXY to prevent injection resin to escape during the injection process. Vertical cracks should always be injected from the bottom upwards. As soon as injection resin oozes out of the next packer/injection port, the first one is sealed and the injection process continued from the next one. After completion of the injection process, the injection ports (packers) as well as the sealing material between the ports are removed.
