High-Performance Brush in Cap Tin Cans for Industrial Applications
When packaging aggressive liquid chemicals, volatile solvents, or high-tack sealants, standard plastic packaging routinely fails due to chemical permeation and container distortion. Industrial formulators require containment that guarantees an absolute vapor barrier paired with instant workflow efficiency.
SeFluid manufactures precision-engineered brush in cap tin cans (widely recognized in the field as brush top tin cans) specifically designed to solve these aggressive liquid storage challenges. Combining cold-rolled electrolytic tinplate with integrated dauber assemblies, these specialized containers prevent premature solvent evaporation, eliminate cross-contamination, and deliver precise dosing directly to the workpiece.

Key Engineering Features of SeFluid Brush in Cap Tin Cans
The structural integrity of metal adhesive containers dictates the shelf life of the chemical inside. SeFluid manufactures every unit using prime MR-grade electrolytic tinplate with a base steel thickness ranging from 0.23mm to 0.28mm, ensuring high crush resistance during palletized transit.
1. Zero-Evaporation Closure Systems
Volatile Organic Compounds (VOCs) demand hermetic sealing. Our screw top dauber cans feature a deep-drawn 1-3/4” (44.4mm) alpha thread neck paired with a PE lined screw cap. When torqued down, the high-density polyethylene inner cone forms a tight 360-degree mechanical wedge against the metal land area. This creates a 100% vapor-tight seal that stops aggressive solvent loss.
2. Tailored Applicator Assemblies
To match varying liquid viscosities, SeFluid equips the cap assembly with three distinct applicator shafts:
- 100% Natural Horsehair Applicator Brush: Stiff yet resilient; engineered for spreading heavy PVC cements, pipe primers, and contact adhesives uniformly without shedding.
- Synthetic Nylon Bristles: Offers high resistance to ester-based solvents, making it ideal for industrial touch up cans holding automotive enamels or machinery coatings.
- Wool Dauber Balls: Features maximum liquid retention, designed for low-viscosity thread lockers, liquid fluxes, and gasket sealants.
The applicator stem is mechanically crimped to a rigid galvanized steel wire, preventing brush detachment even after prolonged submersion in high-tack chemical formulations.
Standard Capacity & Dimensional Specifications
SeFluid maintains standardized tooling for rapid B2B order fulfillment. All configurations below utilize the universal 1-3/4″ screw thread standard:
| Nominal Capacity | Metric Equivalent | Body Diameter (mm) | Overall Height (mm) | Recommended Applicator |
|---|---|---|---|---|
| 4 oz | 125 ml | 65 | 60 | Horsehair / Wool Dauber |
| 8 oz | 250 ml | 65 | 100 | Horsehair / Nylon |
| 16 oz | 500 ml | 84 | 118 | Horsehair |
| 32 oz | 1000 ml | 112 | 145 | Heavy-Duty Horsehair |
Internal Coatings for Chemical Compatibility
While raw, unlined tinplate is the gold standard for petroleum distillates and oil-based lubricants, PVC cement packaging or water-based primers will corrode bare steel over time.
To guarantee broad chemical compatibility, SeFluid applies an internal phenolic epoxy gold lacquer at a dry film weight of 5–8 g/m². This high-bake inert lining isolates reactive compounds from the iron substrate, preventing internal rust flaking and preserving the clarity of transparent liquid sealants.
Why Global Formulators Source From SeFluid
Sourcing tinplate solvent cans leaves zero margin for leaking failures. SeFluid enforces strict manufacturing benchmarks across our automated welding lines:
- 100% Online Leak Testing: Every single container passes through an automated dry-air differential pressure test at 0.03 MPa prior to packing.
- Triple-Seam Bottom Construction: The body-to-end juncture utilizes a 7-layer double seam reinforced with a high-nitrile non-curing lining compound.
- Lithographic Customization: We provide 4-color CMYK metal offset printing directly onto the tinplate shell, eliminating the peeling, wrinkling, and adhesive degradation common to paper labels.
Часто задаваемые вопросы (FAQ)
Can SeFluid customize the brush stem drop length?
Yes. We engineer the exact wire stem length based on the internal height of your specified can. The brush tip is set to hover exactly 2mm to 3mm above the bottom interior dome, ensuring maximum liquid evacuation without bending or permanently splaying the bristles.
Are your chemical grade tin cans certified for hazardous shipping?
Our 16 oz and 32 oz heavy-duty models can be supplied with UN Certification (1A1/Y rating) upon request, making them fully compliant for international air and sea freight of flammable Class 3 hazardous liquids.
What is the Minimum Order Quantity (MOQ) for custom lithography?
For plain silver unprinted containers, our MOQ is 3,000 units. For customized lithographic printed cans, the MOQ is 15,000 units per SKU to cover plate-making setups.
How do I choose between a horsehair brush and a wool dauber?
Select a horsehair brush for high-viscosity liquids (such as CPVC cements or acoustic mastics) that require mechanical scrubbing pressure to bond to substrates. Choose a wool dauber for thin, watery fluids (like purple PVC primer or metal etching washes) where smooth, drip-free wicking action is prioritized.
