Scale & Corrosion Inhibitor plus Anti-foulant for High Silica Waters - Bottle

Scale & Corrosion Inhibitor plus Anti-foulant for High Silica Waters - Bottle

Accepta 6018 is a high performance, highly concentrated solid chemical cooling water scale and corrosion inhibitor scientifically formulated for the treatment and protection of cooling water systems operating under high silica water conditions.

Accepta 6018 uses the very latest anti-scaling, anti-fouling and corrosion inhibition technologies. Its scale dispersant and corrosion inhibitors work with conventional chemistry to provide system protection at low product dosage rates.

Accepta 6018 is available in fully recyclable plastic bottles each containing 5kg of concentrated solid chemical.

Accepta 6018 contains PBTC phosphonate, HEDP phosphonate, a dual polymer package (Versaflex SI and AR-540), and triazole.

Accepta 6018 is available in fully recyclable plastic bottles each containing 5kg of concentrated solid chemical.

Accepta 6018 is packaged in cases containing 4 x 5kg bottles.

Each case weighs 20kg.

Application & Dosage Information

Versaflex SI is a complex polymer specifically designed for silica and magnesium control in cooling water systems. Versaflex SI has demonstrated control of silica to a concentration above 250 ppm (as SiO2) in pilot and field studies.

To start, formulations should contain between 15 – 20 ppm of Versaflex SI on a dry basis, in the re-circulating water.

Recommended Dosage Rates 

Level Dosage Test target SiO2 limit SiO2 limit
SI (active)
Chemical level in
recirculating water
Organo-phosphate at pH > 8.5 at pH < 8.5
20 ppm 150 ppm 20 ppm 300 ppm 275 ppm
10 ppm 75 ppm 10 ppm 250 ppm 225 ppm

The recommended start-up dosage rate (charging systems) for Accepta 6018 is 100 ppm. This is equivalent to 0.36kg per 3.6m3 of system volume.

At a dosage rate of 20 ppm, 1 case of Accepta 6018 is equivalent to approximately 227kg of a conventional liquid product. Comparative values will vary, dependent upon concentration.

Testing & Control

Organophosphonate test kits suitable for monitoring and controlling the use of Accepta 6018 are available from Accepta.


Feed Accepta 6018 using an Accepta board system.

It is always advisable to carry out a 'Control Of Substances Hazardous to Health' (COSHH) assessment before use.
