VANQUISH 100 is based on the active agent N-butyl-1,2- benzisothiazolin-3-one (BBIT). It is a broad spectrum antimicrobial used to (1) prevent fungal, bacterial and algal spoilage of polymers such as PVC, polyurethane, silicone, polyolefin, polyester (and others ) and (2) to impart surface activity on plastics or dry paint films to give a hygienic or antibacterial effect. VANQUISH 100 is recommended for use in tough and demanding applications especially those exposed to high UV levels.

Applications

VANQUISH 100 can be used to preserve and/or impart a surface effect on PVC, silicone, polyolefin, polyurethane and acrylic articles such as:

• Shower curtains
• Coated fabric (e.g. ski wear, raincoats, tents etc.)
• Vinyl wall coverings, floor coverings, underlay & mats
• Swimming pool, pond and ditch liners
• Conveyor belts
• Shoe soles and mid-soles
• Roofing membranes
• Auto parts (e.t. landau tops, door seals, shock absorbers, steering wheels etc.)
• Foam (e.g. seat cushions, gaskets, insulation etc.)
• Electrical & pipe wrap
• Appliance gaskets such as washers, refrigerator etc.
• Tarpaulins and awnings
• Hygienic wall and floor coatings

Antimicrobial properties

The efficacy of VANQUISH 100 was evaluated by the calculation of Minimum Inhibitory Concentrations (MICs) [Table 1]. MICs do not represent effective use levels but do indicate the intrinsic broad spectrum of antimicrobials. VANQUISH 100 has a non-specific mode of biocidal action which means that bacterial resistance is very unlikely to occur.

Use guidelines

VANQUISH 100 may be used for the manufacture of liquid or solid antimicrobial formulations. VANQUISH 100 may also be used for direct incorporation into plastics or their precursors to preserve plastic articles from microbial degradation or to impart a hygienic surface effect.

The activity of VANQUISH 100 has been further demonstrated under conditions representative of practical use. However, it is recommended that you carry out tests under practical conditions to determine the most cost-effective dose for your application.

Incorporation of VANQUISH 100

PVC Plastisols: For addition to PVC plastisols, VANQUISH 100 may be added along with the other additives. Use levels should be calculated based upon the total weight of the formulation.

PVC：VANQUISH 100may be added to the mixed liquid components, added to a blend of PVC resin andsolids, shear mixed until a dry blend is achieved and then processed through extrusion, calendering, moulding or other system.

Cross linked Polyurethane: For addition to cross linked polyurethanes, VANQUISH 100 should be addedto the polyol at a concentration that will yield the desired use level in the final product after reaction with the isocyanate component.

Melt Processed Polymers: For addition to melt processed polymers (PVC, thermoplastic polyurethane, synthetic elastomers and thermoplastic acrylics etc.), VANQUISH 100 may be metered into the melt to yield the desired end use concentration (e.t. at the mixing zone in an extrusion system).

Alternatively, VANQUISH 100 may be made into a masterbatch granule (as above at up to 20% VANQUISH 100) and the masterbatrch blended with non preserved polymer in the user’s plant to yield the desired end use concentration upon subsequent melt processing. For thermoplastic polyurethanes, concentratedgranules may also be produced by absorbing VANQUISH 100 liquid into granules through shear mixing (up to 20% VANQUISH 100). These can be blended with non-preserved polymer granules in the user’s plant to the desired use concentration and then further melt processed (i.e. via extrusion).

Acrylics: In addition to the above, VANQUISH 100 can be added to the liquid monomers before polymerization, at levels to yield the desired use level in the final product after polymerization.

Natural Rubber: VANQUISH 100 can be added to the latex.

Polyolefins: VANQUISH 100 may be made into a masterbatch granule (up to 5-10% VANQUISH 100).

Hygienic coatings: Antibacterial or hygienic coatings can be formulated by the direct incorporation of VANQUISH 100 into the coatings system. Please refer to the detailed application information document for more information.
