Description
Vetoflex PU788 is one part, moisture curing, water resistant, low modulus elastomeric joint sealant based on polyurethane. It is suitable for movement and connection joints for indoor and outdoor applications. Vetoflex PU788 is a weather-resistant, paintable sealant when it’s fully cured, with versatile usage both as a sealant and a general adhesive in the construction industry for various substrates, including concrete, steel, wood, and many others.
Features and benefits:
- Suitable for overhead, vertical, and horizontal joints.
- Weather-resistant, suitable for external and internal applications.
- Easy application using a caulking gun.
- Paintable with non-solvent or water-based paints after curing in static joints (e.g., around door perimeters).
- No cracking or crazing under UV exposure.
- Non-sag and non-staining.
- Does not require a primer and exhibits tenacious adhesion to most building materials.
- Excellent movement accommodation.
Vetoflex PU788 use should follow standard concrete joints practices; sealants need either backing rod or joint breaker tapes to prohibit 3 point adhesion and allow movement freedom in the desired design. Vetonit recommends the use of ACI 224.3-95 (re-approved 2013) for joint design.
Standard design dimensions for concrete elements as per DIN 18 540 /table 3.
Technical data:
- Effects of Heat Ageing ASTM C1246: No cracking and chalking.
- Joint Movement Capability ASTM C719: ±25%.
- Sagging - ASTM C639: 4.8 mm.
- Extrusion Rate - ASTM C1183 at 14 days moist cure: ≥10 ml/min.
- Curing Rate: ~ 2 mm/24 h.
- Tack Free Time - ASTM C679: <3 hours.
- Peel Adhesion ASTM C794 at 21 days: > 22.2 N.
- Effects of Accelerate Weathering ASTM C793: No crack.
