Vetoflex AC730

High performance, antifungal, multi-purpose acrylic joint sealant.

Vetoflex AC730 is a single-component, high-performance, multi-purpose acrylic emulsion-based joint sealant that cures by the loss of carrier to form a flexible seal. It is applied directly from the cartridge and can be finished neatly using suitable tools. When cured, it will accommodate small thermal, shrinkage, and moisture movements. It can be overcoated with most gloss or emulsion paints.

Uses

  • Crack filling.
  • Around window and door frame surrounds.
  • Curtain walling and precast construction.
  • Joints in blockwork and brickwork.
  • Sealing composite and lightweight cladding panels, etc.

Advantages

  • Flexible.
  • Antifungal.
  • Solvent free.
  • Non-Cracking.
  • Low VOC content.
  • Excellent adhesion.
  • Excellent weather ability.
  • Can be overcoated (Paintable).
  • Cures at room temperature at ambient humidity conditions.
  • No surface pre-treatment or primer required in most of the surfaces.

Usage Instructions

Joint surfaces must be clean and dry. Remove all dust and laitance by grit blasting, grinding, or rigorous wire brushing. Blow all joints clean using dry, oil-free compressed air. 
Where a neat finish is required, masking tape should be applied down each side of the joint prior to the start of the sealant work. It should be removed immediately after tooling the sealant

Vetoflex AC730 can be applied by hand or with an airoperated caulking gun. Ensure that the sealant is pushed firmly into the joint to achieve complete wetting of the surface. 
Any tooling of the sealant surface must be carried out immediately using a joint shaping tool soaked in white spirit or a wet sponge. If required, the edges of the joint can be protected with masking tape. If this is done, ensure that the tape is removed immediately after tooling

Remove Vetoflex AC730 from tools and equipment with water immediately after use. Cured material can only be removed mechanically.
