Tectyl® corrosion preventive coatings help protect machinery, spare parts and metal components during storage and transport. When equipment reaches site, the next question is practical: does the protective film need removal before commissioning—and which method should be used?
Tectyl coating removal, also called de-preservation, depends on the exact product, the equipment manufacturer’s instructions, the coated surface and the equipment’s intended service. A method suitable for exposed metal may be unsuitable for nearby paint, seals, bearings or electrical components.
White House General Trading LLC supports Tectyl product selection and technical enquiries across the UAE, GCC, Middle East and Africa.
Does Every Tectyl Coating Need Removal?
No. Films may need removal from machined fits, sealing faces and other areas where residue could interfere with assembly or operation. Other protective coatings are intended to remain in place.
Tectyl 502-C is one example: the manufacturer describes its use inside gearboxes without removal after installation, where it dissolves into the oil. Confirm that this application is acceptable for the specific equipment and lubricant before leaving the film in place. Tectyl 502-C manufacturer guidance.
Before selecting a cleaner, establish:
- The exact preservation product applied
- The surfaces and components protected
- Whether removal is required before service
- The methods permitted by the product documentation
- Any additional OEM or project acceptance requirements
If the coating is unidentified, check preservation records, packaging labels or supplier documentation before proceeding.
Tectyl 150 and Biocleaner: Which Should You Consider?
Both products support de-preservation, but selection must account for the coating and equipment.
| Consideration | Tectyl 150 | Tectyl Biocleaner |
|---|---|---|
| Product type | Solvent-based remover | Water-based, biodegradable cleaner |
| Manufacturer-described use | Removal of cured and uncured solvent-based Tectyl coatings; also degreasing | Removal of oils, greases and compatible Tectyl coatings |
| Preparation | Used as supplied | Concentration selected according to the coating, contamination and application |
| Application guidance | Spray gun, or cloth for small areas | Apply, allow to soak, then rinse thoroughly with clean water |
| Contact time | Approximately 3–6 minutes | Depends on concentration, contamination, temperature and method |
| Compatibility check | Confirm suitability for the coating and surrounding materials | Test before use to prevent unintended paint removal |

The cleaner’s carrier does not determine which coating it can remove. A water-based cleaner is not automatically suitable for every waterborne coating. Check the exact coating’s removal instructions.
Use the current technical data sheet (TDS) and safety data sheet (SDS) applicable to the supplied product. Regional formulations and document revisions may differ.
Prepare the Equipment and Work Area
Review the preservation instructions, equipment manual and relevant product documents. Identify what needs cleaning and protect components that could be affected by cleaner, loosened film or rinse water. Pay particular attention to electrical enclosures, bearing housings, breathers, seals and open connections.
Plan how cleaning liquid and removed coating will be collected. Follow the SDS and site requirements for ventilation, personal protective equipment, ignition control and waste handling. Test a small, suitable area before treating sensitive surfaces. Check for changes to paint, plastics, elastomers and surface finish.
Check Surface Temperature in Gulf Conditions
Tectyl 150’s manufacturer guidance recommends a substrate temperature of 10–35°C at application. Its European technical documentation lists a typical flash point of 40°C. Flash point is a separate property and should not be treated as an application limit. See manufacturer guidance and downloadable technical documents.
Measure the actual surface temperature. Shade or an early start may help manage conditions, but neither confirms that the substrate is within the recommended range.
Remove the Film Using the Product-Specific Procedure
Work in manageable sections and follow the selected product’s instructions for concentration, application, contact time, removal, rinsing and drying.
For Tectyl 150, the manufacturer describes application as supplied, approximately 3–6 minutes contact time, followed by removal using high-pressure water, preferably hot water or steam. Use that procedure only where the equipment and surrounding components can tolerate the specified cleaning method. If water or steam cleaning is unsuitable, obtain a compatible alternative procedure before starting. Tectyl 150 application guidance.
For Biocleaner, select concentration and exposure time according to the current instructions and application. The manufacturer describes soaking followed by thorough rinsing with clean water, with repeat treatment where necessary. Biocleaner application guidance.
- Apply the cleaner to the intended area.
- Allow the specified contact time.
- Remove the loosened film using the permitted method.
- Collect residue and cleaning liquid.
- Inspect the section before continuing.
Prevent cleaner and loosened coating from entering sensitive components or inaccessible passages. Do not improvise dilution ratios, mix cleaners or substitute products without confirming compatibility. Internally preserved equipment requires an OEM-approved procedure; a clean exterior does not establish that internal assemblies are ready for operation.
Inspect Before Installation or Commissioning
Check required surfaces for residual film, trapped liquid, contamination and corrosion. Focus on machined fits, gasket and sealing faces, threads, recesses, accessible cavities, and lubrication and process connections.
Dry cleaned areas as required and minimise the time exposed metal remains wet. Complete specified lubrication, reassembly and functional checks. Use the OEM’s or project’s acceptance criteria to determine cleaning completeness. Visual inspection may be sufficient for some accessible surfaces; other applications require additional checks.
If corrosion or damage is found, assess it before commissioning. Coating removal alone does not establish fitness for service.
What If Commissioning Is Delayed?
Cleaned surfaces may need renewed protection if installation or start-up is postponed. Review the revised storage period, site exposure and OEM requirements before deciding whether to re-preserve the equipment.
Record the product applied, treated areas, application date and next inspection requirements. This gives the commissioning team a clear account of what remains on the equipment.
De-preservation Checklist
- The preservation product has been identified
- Removal requirements have been checked
- The cleaning method is suitable for the coating and equipment
- Sensitive components were protected during cleaning
- Required surfaces have been cleaned, dried and inspected
- Residue and cleaning liquid have been collected and handled appropriately
- Corrosion or damage has been assessed
- Required lubrication and equipment checks are complete
- The work has been recorded and accepted under the project procedure
Frequently Asked Questions
Can Tectyl coatings remain on equipment during operation?
Some can remain in their intended applications. Tectyl 502-C, for example, is described by the manufacturer for gearbox preservation without removal after installation. Confirm the application, lubricant compatibility and OEM requirements.
Can I use one cleaner for every Tectyl coating?
Do not assume universal compatibility. Check the coating’s removal instructions and the proposed cleaner’s technical documentation.
How long does Tectyl 150 take to work?
The manufacturer specifies approximately 3–6 minutes before removal using its described rinse procedure. Check that this procedure is suitable for the equipment being cleaned.
Is Biocleaner safe for painted surfaces?
Compatibility must be checked. The manufacturer recommends testing before use to prevent unintended paint removal.
Should removal be considered when choosing a preservation product?
Yes. Plan for both preservation and return to service: protection requirements, cleaning access, material compatibility and removal methods all affect product selection.
