Heavy Duty Epoxy Urethane Joint Sealant
Vetoflex PU785 is a two component self-leveling epoxy modified polyurethane joint sealant. It can be poured directly into horizontal joints in order to form a tough resilient seal containing a limited degree of flexibility. Vetoflex PU785 can accommodate small amount of movement in expansion and contraction but can take high compressive stresses.
Withstands steam cleaning.
Excellent adhesion to concrete and asphaltic substrates
Extremely resistant to chemicals and hydrocarbon
Self-leveling to produce uniform and neat joints
Permanent and uniform water-tight seal
Suitable for use in wide joints
Good mechanical properties for heavy duty limited movement applications
Compatible for use in horizontal areas with a maximum slope gradient of 10%
Vetoflex PU785 is supplied in 4 Liters Kit

Stated consumptions data are for general guidance. Actual consumption depends on the nature of substrate, method of application and wastage.
Original sealed container of Vetoflex PU785 has a shelf life of 12 months provided it is stored clear of ground in a dry shaded place below 25ºC.
Vetoflex PU785 is supplied in pre-weighed two part packs, which requires on site mixing. Pour the hardener (PART B) into the base (Part A) pail and mix thoroughly with a slow speed drill (300-400 rpm) fitted to a flat bladed paddle for 5 minutes till a uniform colour and consistency is achieved.
Since the base and the curing agent ratio controls the ultimate physical properties like adhesion, durability and strength, one complete kit has to be mixed at a time. The side and base of the container shall be periodically scrapped with a scraper to ensure that the curing agent is properly dispersed and blended in the mix.
Pour the mixed material directly into the joint from the pail. Initially fill 2/3 of the sealant, tool it properly allowing it to fill all the irregular areas inside the joint. The tooling will also allow entrapped air to escape. Then pour the balance 1/3 material and further tool it to get a smooth surface finish. The material should be used completely within the specified pot life. Once the sealant has been installed a suitable rounded tool soaked in soapy water can be used to achieve an hour glass profile. Any masking tape applied should then be removed immediately after the sealant is installed.
Vetoflex PU785 should be removed from tools, equipment and mixers with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.
The joint surface must be clean, dry and free from oil, loose particles, cement laitance and other contaminants which may affect the adhesion. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound substrate. The compressible joint filler shall be cut back to expose a uniform joint depth.
Vetoseal XX777-25 should be applied to clean, dry surface prior to the installation of backer rod or bond breaking tape. The primer shall be applied by a brush in a thin coat application and shall be allowed to become tack free prior to the application of the sealant. The joint edges shall be re-primed if the sealant installation is not carried out within 3 hours of application of the primer. For obtaining a clean and neat finish, masking tape shall be applied on both the edges of the groove before applying the primer.
Avoid contact with skin or eyes. During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
