Description Use

A combination of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-iothiazolin-3-one. SM-15P is a broad spectrum anti-microbial/slimicide product designed specifically for the control of bacterial and fungal slime in pulp and paper mill systems. Advantages of SM-15P include:

• 1.Broad spectrum control of micro-organism in paper mill systems.
• 2.Easy handling in liquid form.
• 3.Effectiveness at low concentrations.
• 4.Resistance to the inhibitory effect of organic and inorganic compounds.

SM-15P is not recommended for use in potable water systems or where contamination of potable water can occur.

Physical Properties

Feed Method

SM-15P may be drip-fed continuously from the drum or fed by any suitable chemical feed system. It should be added to a point in the system to insure uniform mixing such as the beater, hydropulper, fan or broke storage pumps. Specific feeding points and schedules will be recommended by an Aurora Specialty Chemistries representative for the particular application.
Dosage will depend upon a number of factors including: the nature and extent of the microbiological contamination, the type and volume of the system being treated, the degree of control desired, and retention time in the system. Where necessary, your Aurora Specialty Chemistries representative will arrange for microbiological and chemical analysis so that technical advice can be given concerning specific cite problems. Dosage will vary from .44 to 1.5 lbs. (7 to 23 fluid ounces) of SM-15P per ton (dry basis) of finished paper produced, depending upon the type of stock, raw water, and degree of contamination. Badly fouled systems should be cleaned before initial treatment.

Special Information

SM-15P meets the requirements of the Food and Drug administration (FDA) for use in the manufacture of paper and paperboard intended to contact food per the following regulations: 21 CFR 176.170 and 176.300.

Handling Procedures

Personnel cleaning up spills should wear impervious overshoes in addition to the usual protective clothing. The spilled material is diked and absorbed in an inert solid such as clay or vermiculite. The absorbent (and surface soil to a depth sufficient to remove all microbiocide) is then shoveled into a pail or drum and treated with enough decontaminant solution to wet the solid thoroughly. Let these containers stand open for 48 hours to avoid the build-up of pressure, then seal and dispose of by burying as landfill. The decontaminated area is washed with additional decontaminant solution and then flushed into a chemical or municipal sewer. Do not discharge spills and cleaning run-offs into open bodies of water.

First Aid Procedures

• Eyes - Flush immediately with water for a minimum of 15 minutes. Contact a physician if irritation occurs.
• Skin - Wash immediately with soap and water. Remove contaminated clothing and wash before re-use.
• Swallowed - Drink large amounts of water. Contact a physician immediately.

Packaging
