DSM has developed a new resin system called AtlacTM Premium for cured-in-place pipe (CIPP) relining that is more environmentally friendly than traditional resins. AtlacTM Premium is label-free and consists of components that do not contain hazardous chemicals, allowing repairs to be done with less disruption and impact on the environment. It offers strong performance for restoring sewer functionality while being safer for workers during installation and imposing no risk of disturbing water purification or polluting the ground. DSM's AtlacTM Premium resin system enables cost-effective pipe relining with improved sustainability.

2. Performance and Sustainability
ensuring the optimum performance of sewer and waste water systems is essential for local and regional governments as well as industrial
organizations to avoid unnecessary disruption. in order to keep these systems working, repairs may be required that can restore functionality with
the lowest possible impact to those in the surrounding area.
dsm has a track record of many successful installations and a proven performance in relining solutions. its atlac™ premium resins can give you
peace-of-mind, offering the best options for consistent sewer functionality while allowing you to make a positive impact on the environment.
Responsible Relining with Atlac™ Premium
Leaking sewage pipes can now be repaired and restored in an environmentally-friendly way with Cured In Place Pipe (CIPP) relining systems based
on Atlac™ Premium resins from DSM. These relining systems offer local and regional governments the opportunity to repair leaking pipes quickly and
cost effectively. CIPP is a robust and well-proven solution that helps you make repairs without causing disruption to traffic, road congestion or unnec-
essary road works.
The relining method of CIPP involves a reinforced liner of glass or felt that is impregnated with a resin system. This liner is then inserted into the dam-
aged or leaking sewer pipe and cured via steam, water or light. After curing, a new composite sewer pipe is created within the pipe, which is even
stronger and longer lasting than the original pipe. The relining system enables long lengths of pipe to be renovated at the same time giving shorter
installation time for the engineer.
Atlac™ Premium System
A number of different resins can be used for making CIPP relining solutions depending on the composition and temperature
of the waste water. For normal sewer conditions, polyester resin is the most commonly used. For more industrial sewer
conditions, which often use higher temperature waste water, vinyl ester and/or epoxy resin systems are normally the
chosen options. With the new Atlac™ Premium resins, DSM combines the advantages of existing resins systems used for
relining with the added benefit of low environmental impact. DSM’s use of label-free components (i.e. components that
have no hazardous chemicals) has enabled it to produce relining technology that offers you cost-effective and less-
disruptive repairs without compromising the environment. Its features include:
- Label-free resins, a major step forward for sustainability;
- No smell, ideal for urban areas and/or residential environments;
- Strong chemical resistance (depending on conditions of the waste water);
- High temperature resistant;
- Mechanical properties meet strict European standards: “EN 13566-4”;
- Impregnation in controlled environment (not at location);
- Curing process can be perfectly regulated by temperature or light;
The ATLAC™ PREMIUM system is part of DSM’s portfolio of products that reinforce our commitment to safe, sustainable solutions.
