Heavy duty, semi rigid epoxy urethane sealant
Vetoflex XS788 is a two component, hybrid epoxy urethane, semi-rigid joint sealant. The product is designed to withstand heavy duty industrial applications. Vetoflex XS788 is a pouring grade self leveling sealant that provides chemical resistance to dilute acids and alkalies while being tough and at the same time providing a limited degree of flexibility.
ASTM C920 Type M, Grade P use T,I, A and M
Vetoflex XS788 stored in 4 Liter Kits
Original sealed container of Vetoflex XS788 has a shelf life of 12 months provided it is stored clear of ground in a dry shaded place below 25ºC.
The use of a primer is generally not required when using Vetoflex XS788. However where hard to bond substrates such as PVC or where highly porous substrates are in question, please contact Saveto local office for assistance on suitable primer choice.
The components of Vetoflex XS788 are supplied in the correct mixing ratio. Add the entire contents of the color pack and hardener component into the base container and mix together thoroughly for three minutes using a slow speed drill (300 to 500 rpm) fitted with a suitable mixing paddle. Ensure any settlement is thoroughly dispersed. The sides of the container should then be scraped down to ensure that any unmixed components do not remain. Mixing should then continue for a further 2
The mixed Vetoflex XS788 can be poured directly from the mixing container by compressing the sides to form a pouring lip. Pour into the prepared joint to the required level, should the joint width prohibit direct pouring from the container, the mixed material can be poured into a Vetoflex Barrel gun and applied to the joint. It may be necessary after a few minutes to top up the level of the sealant after it has flowed into all joint irregularities. Finally, strip of any masking tape that may have been used
Vetoflex XS788 should be removed from tools, equipment and mixers with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.
Clean all joint surfaces and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits or algae. Roughen the surfaces, remove any laitence and expose aggregate by light scabbling or grit-blasting.
Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser.
Any expansion joint filler must be checked to ensure it is tightly packed and no gaps or voids exist at the base of the sealing slot before positioning a bond breaker. The use of a bond breaker is not required in expansion joints containing cellular polyethylene joint filler, backing rod (Vetoflex PBR). For construction or contraction joints a bond breaker tape or back-up strip must be used. Where a particularly neat finish is required, mask the face edges of the joint before sealing and remove immediately after tooling is completed.
