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 to form a tough, resilient seal containing a limited degree of flexibility. Vetoflex PU785 can accommodate a small 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 a 4 Liters Kit.

Stated consumption data are for general guidance. Actual consumption depends on the nature of substrate, method of application, and wastage.
The original sealed containers of Vetoflex PU785 have 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) container and mix thoroughly with a slow speed drill (300-400 rpm) fitted to a flat-bladed paddle for 5 minutes till achieving a uniform color and consistency.
Since the base and the curing agent ratio control the ultimate physical properties like adhesion, durability, and strength, one complete kit has to be mixed at a time. Scrape the container's sides periodically 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 container. Initially, fill 2/3 of the sealant, tool it properly, and 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. Use the material completely within the specified pot life. Once the sealant has been installed, use a suitable rounded tool soaked in soapy water to achieve an hourglass profile. Remove any masking tape applied immediately after installing the sealant.
Remove Vetoflex PU785 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, affecting the adhesion. It may require a thorough wire brushing, grinding, sandblasting, or solvent cleaning to expose a clean and sound substrate. Cut back the compressible joint filler to expose a uniform joint depth.
Vetoseal XX777-25 should be applied to a clean, dry surface before installing the backer rod or bond-breaking tape. Apply the primer in a thin coat application by a brush, and allow it to become tack-free before the application of the sealant. If the sealant installation is not carried out within 3 hours of applying the primer, reprime the joint edges. For obtaining a clean and neat finish, apply masking tape on both groove edges 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.
