Product overview
BIT 20% is an isothiazolinone-based preservative typically supplied as an aqueous concentrate. It is used to protect water-based industrial products from microbial contamination that can cause odor, discoloration, viscosity drift, gas formation, package swelling, and surface defects.
Commercial value
Helps reduce scrap, rework, and returns by stabilizing product quality across storage and distribution—often lowering total cost of quality.
How it’s used
Typically dosed at low levels (active basis) based on contamination pressure and matrix—validated via your lab/pilot protocol and local requirements.
Where it’s common
Paints/coatings, polymer dispersions, adhesives, construction emulsions, industrial cleaners, and compatible aqueous intermediates.
Process fit
Often integrated into final let-down or post-cooldown stages with good mixing to ensure uniform distribution and stable performance.
Program approach
Can be used as a standalone preservative or within a multi-active program depending on spectrum targets and in-use contamination exposure.
Note: Actual performance depends on formulation matrix, pH, temperature, contamination load, packaging, and other raw materials. Always validate compatibility and dose; follow local regulatory requirements for your market.
Applications
Typical usage patterns for BIT 20% as an in-can preservative in compatible water-based systems. Share your process and constraints and we’ll align the right specification and commercial lane.
- Water-based paints & coatings (in-can preservation)
- Latex emulsions and polymer dispersions
- Adhesives and construction emulsions
- Industrial & institutional cleaners (water-based concentrates/RTU)
- Aqueous slurries and selected process intermediates (program dependent)
- Compatible process fluids where in-tank microbial control is required
Formulation reality check: Microbial control is not only chemistry—sanitation, water quality, packaging, and process hygiene strongly influence outcomes. Share your operating environment to account for contamination pressure and storage conditions.
Technical alignment
Key items technical teams typically confirm before approving an isothiazolinone-based in-can preservative.
Compatibility screening
Confirm compatibility with your resin/emulsion system, surfactants, salts, fragrances/dyes, and other additives. Share any known “no-go” chemistries and sensitivity constraints.
Process & addition point
Identify the best addition stage (often final let-down or cool-down), mixing intensity, and hold times. Uniform distribution improves batch-to-batch consistency and reduces localized overconcentration.
Micro-risk profile
Define contamination pressure (water quality, ambient temperature, repeated opening, storage duration, hygiene controls). Higher risk environments may require complementary actives as part of a program.
Performance verification
Validate using your internal protocol (storage stability, in-use simulation, challenge testing where applicable). Confirm that odor, viscosity, appearance, and package integrity stay within spec.
QA release checks
Typical checks for BIT 20% solutions include assay/active content, appearance, density, pH, and identification per supplier method. Final acceptance should rely on the batch COA provided with your shipment.
Regulatory & labeling
Requirements vary by region and end-use. We support your review with available SDS/COA and origin documentation (as applicable), aligning the offer to your compliance and labeling constraints where possible.
Dose & program notes
Dose selection is formulation-specific and should be validated under your real storage and use conditions. Many teams size dosage based on contamination pressure, pH window, packaging exposure, and shelf-life target.
- Screen in the lab; confirm in pilot or early production
- Consider water quality, sanitation, packaging, and headspace exposure
- Evaluate single-active vs. blended program depending on your risk profile
We can help you structure the input data needed for a faster technical review (matrix, constraints, acceptance criteria).
Safety note: Use only in industrial applications aligned with applicable laws and regulations. Follow SDS guidance for handling, storage, and disposal.
Performance & use guidance
Procurement-friendly technical notes for aligning the right offer.
Typical dose range
Often used in the low hundreds of ppm (active basis), depending on contamination pressure and matrix. Final dose must be determined by lab/pilot testing and regulatory requirements.
Addition point
Commonly added during final let-down or cool-down to support stability and distribution in the batch. Ensure good mixing and avoid localized overconcentration.
Program approach
May be used alone or as part of a preservation program with complementary actives depending on micro-spectrum targets, packaging exposure, and in-use contamination risk.
Risk drivers
Warm storage, high organic load, poor sanitation, and repeated container opening increase spoilage risk. Address hygiene and packaging along with preservative choice.
Quality checks
Typical procurement checks include active content (assay), appearance, density, pH (solution), and identification per supplier method.
Handling
Follow SDS for PPE and safe handling. Avoid aerosol generation and skin contact; store sealed in a cool, ventilated area.
Documentation & traceability (what you can request)
SDS
Handling, exposure controls, storage guidance, and transport notes (where applicable).
COA
Batch-specific results (assay/active, appearance, and grade-dependent parameters).
TDS
Typical properties and grade description (availability varies by origin and grade).
