Isothiazolinone based ProShield PC55 RO Biocide bactericide an antimicrobial and preservative used in a wide variety of applications, such as bactericide for reverse osmosis water treatment.

Non-oxidizing antimicrobial formulation developed for microbial control in reverse osmosis (RO) water treatment systems. It is based on glutaraldehyde, a broad-spectrum biocidal active ingredient effective against bacteria, fungi, algae and other microorganisms.

The product helps control microbial contamination, biofilm formation and biological fouling in RO pretreatment and compatible membrane systems. It is suitable for use in industrial water treatment applications where microbial growth can reduce membrane performance, increase differential pressure and affect permeate production.

The formulation is intended for controlled biocide treatment, system sanitization and microbial growth management, subject to membrane-material compatibility and manufacturer recommendations.

This chemical quickly biodegrades.

With a shelf time of one year when stored at room temperature in a dark, air-tight, and moisture-proof place.

Isothiazolinone Biocide is high performance, broad spectrum, antimicrobial agents based on the proven isothiazolone chemistry. Isothiazolinone Biocide 14% is excellent Isothiazolinone biocide and Oilfield Bactericide. They are effective at very low concentrations in controlling both the planktonic and surface growth of bacteria, fungi and algae and have been produced specifically for water treatment and paper mill applications. It could be used Isothiazolinone in water treatment and Oilfield Bactericide applications

The bactericidal effect of Isothiazolinones Biocide Cooling Water Treatment is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes,Isothiazolinone can quickly inhibit their growth, thus leading to death of these microbes.Isothiazolinones has strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, noresidual, safety in operation, good compatibleness, good stabilization, low cost in operation.

Application  :

Isothiazolinone as chemical biocide algaecide is ideally suited to meet the requirements of an industrial water treatment biocide and excellent Isothiazolinone biocide. Isothiazolinone 14% microbicide is not deactivated by suspended organic matter, and is compatible with other water treatment additives, including chlorine. With the recent change of many cooling towers and paper mills to alkaline operating conditions, it is important to use a biocide such as Isothiazolinone 14% which remains stable at higher pH values. Isothiazolinone 14% is of low toxicity at use levels, easily deactivated and biodegradable.

Application Field  / Industry :

• Adhesive industry
• Construction industry
• Gypsum, plaster and mortar
• Laundry and cleaning agents
• Lubricant/coolants
• Paint and coatings industry
• Paper manufacture
• Technical suspension/emulsion
• Textile and leather industry
• Water treatment 

Dose :

When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with oxidative fungicidal such as chlorine, and no used in cooling water system containing sulfur. When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.

Technical Specification :

Storage & Handling

Do not store in direct sunlight. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Keep container tightly closed. Avoid ingestion and inhalation.
