5 kg liquid protective film pail
Peelable Protective Coatings for Irregular-Shaped Parts
Peelable Protective Coating for Irregular-Shaped Parts
A liquid protective film for curved components, recesses and complex surface geometries. The coating follows the workpiece and forms a removable barrier for handling, processing and temporary protection.
- Packaging
- 5 kg, 18 kg and 200 kg plastic containers; 1,000 kg IBC
- Shelf life
- 3 years in the original sealed container under the stated storage conditions
Surfaces & applications
3C components, injection-moulded parts, etched glass, sintered stone, coated metal and curved manufactured parts.
Protection that follows the component
The water-based polyurethane material forms a protective layer across accessible curves, edges and irregular surfaces. Uses include 3C components, injection-moulded parts, etched glass, sintered stone, painted surfaces and selected metal equipment. The liquid application approach is useful where a pre-cut film would require extensive trimming or leave many joins.
Manufacturing and inter-process uses
Application areas include masking for painting and baking operations, protection of plated or anodised surfaces, and protection between processing stages. Chemical and heat-related duties need to be defined by the actual medium, temperature and dwell time. The technical description identifies acid, alkali, water and abrasion resistance as selection features; the particular production exposure remains the basis for the sample trial.
Selecting an application process
The material can be applied by spray, brush, roller, scraper, dipping, flow coating, coating machine or screen process. Choose a method that reaches the required contours and leaves a continuous film without trapped pools. Professional application equipment is appropriate for production use. The removal path should be considered before coating a part with enclosed recesses or undercuts.
Storage and material condition
Keep the original packaging sealed at 5–30°C. The stated shelf life is three years under these conditions. Material beyond its storage life requires inspection before use. Exposure below −5°C can cause viscosity changes or freezing, so cold-exposed material should return to normal temperature and be checked before application. Refer to the matching safety data for handling and transport arrangements.

Application process
Protection through the complete cycle
- 01
Describe the full process
Identify substrate, finish, geometry, chemical contacts, temperature cycle and the intended removal point.
- 02
Prepare the component
Remove contamination and establish a clean, compatible surface. Test sensitive finishes separately.
- 03
Apply continuously
Use the selected equipment to cover contours evenly. Inspect edges, joints and recessed areas for gaps or excessive material.
- 04
Complete the protection cycle
Allow the film to form, carry out the intended handling or process, then remove it and inspect the original surface.
- 05
Record the result
Record application conditions, removal behaviour and any residue or surface change so repeat work uses the same defined process.
Choose an application method that reaches the protected surfaces without trapping liquid in recesses. Clean the workpiece and establish an even film on a sample part. Test the complete process, including any chemical or thermal exposure, before peeling and inspecting the substrate.

From evaluation to supply
Start with a sample.
Free samples are available; freight is paid by the customer. Order quantities vary by product and packaging. Many bulk coatings start at approximately 50 kg; contact sales for a flexible starting quantity. The usual order lead time is 10–20 days after details are confirmed, with shipping time additional. Include OEM requirements in your enquiry.
Frequently asked questions
Why use a liquid coating on shaped parts?
A liquid can follow curves and details that require cutting and joining when using sheet film. The trial determines whether coverage and removal are suitable for the specific shape.
Does suitability for one process cover every chemical or heat cycle?
No. Chemical concentration, exposure time, temperature and the underlying surface must be assessed for the specific process.
Which bulk packages are available?
The listed options are 5 kg, 18 kg and 200 kg plastic containers and a 1,000 kg IBC.
Can it be used for a hot or chemically exposed process?
Such applications are within the product's described selection scope. Provide the precise temperature, dwell time, chemical and concentration so the coating can be evaluated against that process.
Can colour be specified?
Colour requirements can be discussed with the order. The standard appearance is milky white; agree the desired protective-film appearance and packaging in the enquiry.
