CAS NUMBER: 2749-70-4
DESCRIPTION:
Biochek 410 is an industrial preservative which effectively inhibits the growth of bacteria, fungi and yeasts in aqueous systems including paints, adhesives, latex emulsions.
Biochek 410 is intended to protect products during storage.
Biochek 410 is compatible with typical ingredients in end-use formulations, However, it should be added separately from amine-containing and strong nucieophilic agents during product formulations.
Mixing Biochek 410 with these agents may cause a reaction between the ingredients that can deactivate BIOCHEK 410.
Biochek 410 Is most active over a pH range of 2.0-9.5.
In some formulations, Biochek 410 has shown efficacy.
In higher pH formulations, If the formulation will have a tirial pH greater than 9.5, laboratory testing is recommended.
Biochek 410 is a violation of Federal law to use this product in a manner inconsistent with its labeling.
However, where the adhesive is heated, Biochek 410 should be added during the cool-down cycle.
Adhesives for which Biochek 410 provides effective in-can preservation are starch, epoxy, polyester, polyvinyl acetate, styrene butacliene, methyl cellulose, acrylic, polyvinyl alcohol, hydroxyethyl cellulose, dextrin and casein.
Add using moderate agitation immediately following cool-down of the emulsion, and prior to pumping into storage tank facilities, Biochek 410 includes polyvinyl acetate, acrylic, vinyl acrylic and styrene butadiene.
These emulsions are the raw materials used in the formulation of p lilts, adhesives, joint cements, pigments and household products.
Add or meter into the final diluted fluid either prior to its addition to the system or after the system has been filled.
Biochek 410 should be thoroughly mixed into the system to assure efficacy.
Biochek 410 added to the concentrate, testing should be r.onducled to assure compatibility.
Biochek 410 is formulated to facilitate incorporation by pumping into the makeup water.
Biochek 410 can be incorporated by pouring if necessary.
Biochek 410 should be incorporated into the makeup water during the grind.
Biochek 410 is an effective in-can preservative for all type of aqueous paints and coatings when used at levels of 500 – 4000 ppm.
The optimum effective concentration can vary with properties of the material being preserved.
Testing to determine the appropriate level for your product is highly recommended.
Biochek 410 is formulated to facilitate incorporation by pumping into the makeup water.
Biochek 410 can be incorporated by pouring if necessary.
Pump or pour using moderate agitation immediately following cool-down of the dispersed pigment and prior to pumping to the storage tank.
Biochek 410 is an effective in-can preservative to protect the pigment during handling, transportation and storage.
Dispersed pigments are used to impart color to many products such as paints and coatings, adhesives and plastics.
Effective protection is achieved between 500 – 2000 ppm.
Optimum effective concentration can vary with properties of the material being preserved.
Testing to determine the appropriate level for your product is highly recommended.
Biochek 410 is formulated to facilitate incorporation by pumping, but can be poured.
Add to fluid concentrates during, or at the end of, mixing prior to filling at concentrations from 30–5000 ppm by weight.
These printing fluids may be further diluted with water by printers so that the final concentration of BIOCHEK 410 is 10 – 2000 ppm by weight.
Biochek 410 includes all types of printing fluid products such as, but not limited to printing, copier and computer inks.
Biochek 410 is compatible with materials such as PVC, polyethylene, polypropylene, Tygon, Teflon and glass.
Biochek 410 is corrosive to mild steel.
Positive displacement pumps are preferred for handling the product.
Biochek 410 offers a wide range of applications, and it can aid the detection of analytes in human serum, plasma, and whole blood samples for a variety of health diseases and conditions.
Biochek 410 is an in-can preservative for aqueous coatings.
Biochek 410 is a combination of 1,2-dibromo-2.4-dicyanobutane and 1,2-benzisothiazolin-3-one.
Biochek 410 offers a broad and balanced spectrum of activity against bacteria, mold fungi and yeasts, thus ensuring a reliable and long-lasting preservative effect.
Biochek 410 is supplied in the form of a beige to light-brown, aqueous dispersion with a virtually imperceptible odor.
Biochek 410 does not contain any VOC-relevant components.
Biochek 410 is suitable for products having a pH range from acidic to weakly alkaline.
SPECIFICATION:
Biochek 410 is tan to light brown in appearance and is comprised of between 18,05 and 19.95% 1.2-dibromo-2,4- dicyanobutane and 6% 1,2-benzisothia.zolin-3-one, shown in order in the chemical diagram below.
USES:
Biochek 410 is typically effective when applied at concentrations shown.
The exact amount necessary for the preservation of any given formulation will depend on the components, storage time, temperature, etc., and can be determined through actual testing representative, All concentrations are based on the total.
As with any product, use of Biochek 410 in a given application must be tested (including field testing, etc.) by the user in advance to determine suitability.
APPLICATION:
-Adhesives: 0.05-0.8%
-Latex Emulsions: 0.05-0.8%
-Metalworking Fluids: 0.05-0,4%
-Aqueous Paints: 0.05-0,4%
-Pigment Slurries: 0.05-0.2%
-Joint Cements: 0.20-0.8%
-Household Products: 0.05-0.4%
APPLICATION:
The growth of microorganisms in aqueous systems during shipment, storage and handling can be detrimental to effectiveness.
Such growth can affect such properties as odor, color viscosity and introduce microbial growth into production equipment and processes.
Biochek 410 is effective in controlling such contamination and can improve the effectiveness and extent the life of materials treated if used according to the instructions given below.
BENFITS:
