Description

EMSEAL AST HI-ACRYLIC

Features 

  • AST is a self-adhering foam tape impregnated with water-based acrylic-modified asphalt emulsion
  • It is an excellent alternative to butyl tape & open-cell polyurethane foam strips
  • Will not dry out and become hard and brittle
  • UV-stable
  • Highly resistant to bugs and vermin
  • Will not extrude from between joints like caulk or butyl tapes
  • Conforms to contours and fills gaps
  • Maintains a seal during thermal expansion and contraction of building
    panels
  • Excellent compressibility and recovery (minimal compression set)
  • Good thermal and sound insulator
  • No shrinkage or blow-out due to closed-cell breakage
  • Supplied with self-adhesive on one side. After removal of packaging,
    material begins gradual expansion – more slowly in cold weather than in hot.
