This rapid cure SIPP resin means that you, for the first time in the Americas, can clean, line, and reinstate a water pipe section within one working day. No other SIPP resin or Cured-in-Place Pipe (CIPP) lining systems can offer this same day reinstatement service.
Resiline 320 best in class features include:

In 2019, polymer Chemist Dr. Ian Robinson developed Resiline 320 to renew potable water pipes. Resiline 320 is a 3rd generation state-of-the-art lining material for use in the in-situ polymeric lining of potable drinking water pipelines and has NSF/ANSI/CAN 61 2022 and UK BS 6920 approvals. It also has ASA/NZS 4020 approval in Australia and New Zealand. Resiline Technical Data is available by clicking the following hyperlink.
Resiline 320 is the sole aliphatic isocyanate polyurea resin utilized for the renovation of water pipelines. Aliphatic isocyanates, free from BPA, VOC, PFOS, PFOA, and pre-fluorinated substances, are typically used in environments with exposure to the elements and/or where strict performance standards are required.
Resiline 320 sets rapidly, with CCTV ready in 15 minutes and service return in 60 minutes. It adheres well to pipes, offers high tensile strength for pressure pipes, has high wet strength, low water absorption, and can be applied to wet and moist pipes, making it ideal for renovating water pipes.
Resiline 320 is designed to be spray applied in coats ranging from 1 to 3mm. With a recoat window of 8 hours, it allows for building uniform liners insitu from 1 to 14mm thick, tailored to specific requirements—such as a 1 to 2mm AWWA Class I water quality barrier lining or an AWWA Class III or IV structural liner.
Resiline 320 liner offers:
2-minute set, start CCTV inspection after 15 minutes, and reapplication after 90 seconds to 8 hours.
Ability to clean, line and reinstate up to 550 feet (150m) of 6 to 12in (150 to 300mm) pipe and return to service in under 12 hours or line 1300 feet (400m) of 20in (510mm) and greater pit to pit.
Liner-pipe adhesion is not essential.
Apply to Cast and Ductile Iron, Steel, Concrete, Asbestos Cement and PVC pipes.
For 4 to 42in pipe with 1 (40 mils) to 14mm (551mils) thickness.
Based on the next generation Aliphatic Poly Isocyanate which is BPA and VOC free.
Pipes 12in diameter and less 1 to 3mm thick lining coat. Pipes greater than 12in apply 1 to 3.5mm thick coat.
Pipes can be reinstated after one-hour with or without the need to install temporary water by pass.
ASTM D638 Short-term Tensile Strength of 5900 psi.
ASTM D790 Short-term Flexural Modulus of 262,000 psi.
6in diameter 3mm thick liner ASTM D1599 Short-term Burst Pressure of 255 psi.
ASTM D570-98 Water Absorption 1.4% @ 21 Days - meets AWWA C222-08 required 21 day value of <2%.
Greater than 250 psi pipe adhesion.
Moisture tolerance – an absolute requirement for renovating aging distribution pipelines.
