ACR 300

Hydrophilic Waterstop Tape, Plugs & Rings

New generation high performance waterstops which expanding up to 300% when in contact with water.

Pronil ACR is a new generation high performance acrylic polymer based expanding tape. It expands up to 300% when in contact with water. In a totally dry state, Pronil ACR will shrink to it’s original installation dimension and re-expand on wetting. Pronil ACR is used in concrete construction for the sealing of construction joints including wall to base connections, pipe entry systems, sealing of openings and interface sections between existing and new concrete. Pronil ACR is easily stored in it’s original moisture-proof wrap in cool, dry conditions away from sunlight.

Technical Data

The increase in volume was measured when specimens were immersed in tap water at 23°C over a 28 day period. Recovery volume was measured when the specimens were removed from the solution and air dried over a 28 day period. This method was repeated over three cycles. The percentage change in volume calculations are all based on the initial volume.

Application Temperature: -10°C / 50°C
Density: 1,40 g/cm³
Shore: 50

The expansion rating is affected according to CaCO₃ and salt content. Contains no traces of Bentonite.
