Rilsan® Active - Overview

Rilsan® coating systems are used for surface protection due to their excellent chemical and mechanical properties.

Rilsan® has been used for more than 15 years as a coating to protect dishwasher baskets because of its excellent resistant to various food products, dishwashing detergents and the temperature cycles in the dishwasher environment.

For more than 35 years ago, the water industry has adopted Rilsan® coating as a solution to protect their piping systems. Rilsan® coating provides a robust protection to the metal piping system against corrosion caused by wide range of synthetic and natural chemicals. Meantime, thanks to its excellent mechanical properties flexibility, high impact resistance, as well as, excellent resistance to cavitation erosion, the piping system is able to maintain its original design aspects after many years of service.

Today, a novel property has been added which inhibits the growth of bacteria on the coated surface. Based on the innovative silver technology, it enables an efficient and durable protection of the surface from bacterial growth while maintaining virtually all intrinsic properties of the Rilsan® polyamide 11 coating.

This property to inhibit the growth of bacteria on the surface is synergetic with the well-known resistance of Rilsan® against corrosion, wear and chemical attack combined with a surface profile which renders the surface easy-to-clean.

The result is a lasting surface protection against the growth of bacteria complementing the existing cleaning procedures.

In accordance with internal evaluation, this novel property is well maintained after the following test criteria

• Abrasion cycles according to ISO 9352-1995 for 1000 cycles
• Salt spray testing for 1000 hours
• Thermal ageing at 130°C for 1250 hours
• Cleaning cycles using hospital detergent for 1500 cycles

Micro-organisms are everywhere around us. Their existences are essential for the survival and well being of life including human beings. However, the uncontrolled proliferations of micro-organisms could create nuisance, and in some cases, especially that of bacteria, could be of high concern.

Various cleaning and hygienic procedures are already in place to control such proliferation but their effectiveness are limited due to various reasons. From this respect, the employment of Rilsan® ACTIVE represents a remarkable step forward in the risk management of bacterial proliferation. It brings an ideal synergy to complement the existing hygienic and cleaning procedures in areas where a high level of hygiene is demanded. Such areas include, but are not limited to, the following:

• Medical establishments, e.g. hospitals and laboratories
• Care centers for children or the elderly
• Domestic animal, e.g. poultry, farms
• Food processing plants
• Catering establishments, e.g. restaurants
• Fresh food storage and display equipment in markets
• Appliances, e.g. refrigerators, freezers and dishwashers
