- 7-minute UV Cure
- Install in Live Flow (under most circumstances)
- No mixing of Resin in the field (factory wet-out & delivered enclosed, in a gel-state)
- Epoxy paste can be applied at the ends for an adhesive seal
- Resin is only reactive to UV-light, therefore no premature set-off as with ambient cure systems
- Glass reinforcing increases structural strength, mitigates shrinkage and allows for a thin wall
- The thin wall allows for future rehabilitation of the remaining pipe segment
- Fully structural repair designed as a 50-year solution
- Tapered edge is bonded to the host wall
- Fraction of full length lining cost or excavation cost
- Extensive performance history (12+ years in the U.S. and Globally)
- Does not shrink
The material is an ECR (E-Glass, Corrosion Resistant) fiberglass mat pre-impregnated with either Palatal P-92 Polyester light reactive resin, or Atlac E-Nova RE 3475 Vinyl Ester light reactive resin. The wet-out procedure is performed at the manufacturer’s plant in Austria (in controlled conditions) and is partially cured during the wet-out procedure transforming the resin into a gel-state for safe handling and transportation (no hardeners are required for onsite field mixing). The resin and glass laminate configuration, as a whole, eliminate any need for inner and outer coatings. The manufacturer provides a specially designed A/B Epoxy for application over the outside of the resin at the laminate ends to create an adhesive seal between the repair and the host pipe. The material is available in a variety of wall thicknesses, and can be overlapped for extended lengths (typical repair is 4ft).
Typically, resin does not have adhesive properties. To ensure a water-tight seal between the sectional liner and the host pipeline wall, a manufacturer-supplied A-B Epoxy system is supplied and incorporated into the repair procedure. When the glass laminate (gel-state) is wrapped on the bladder, the A-B epoxy paste is mixed on a flat surface and applied towards the laminate ends.
The applicator (silicone bladder) extends beyond the laminate edge therefore creating a beveled edge against the host wall, compressing the epoxy between the host wall and resin laminate. The result is a sealed, smooth transition to the sectional liner.
