What is Intersleek 1100SR Part A and why choose it?
INTERSLEEK 1100SR PART A is the base component of an advanced fluoropolymer foul release coating system designed for the control of slime on ship hulls and other immersed marine surfaces. Used as part of the Intersleek 1100SR multi-component system, it provides a high-gloss, biocide-free silicone fluoropolymer finish that complies with the International Convention on the Control of Harmful Anti-fouling Systems on Ships, 2001 (AFS 2001). It is suitable for both newbuilding projects and maintenance and repair work where low slime adhesion and easy cleaning are required.

Thinning is not recommended. International GTA007 may be used only in exceptional circumstances and must not be added beyond limits set by local environmental legislation.
5. At what temperatures can the coating be applied?
The minimum acceptable substrate temperature at application is 0°C. The surface to be coated must be at least 3°C above the dew point, and a minimum relative humidity of 30% is required for satisfactory curing.
6. How soon after application can the vessel be flooded or returned to service?
Depending on temperature, minimum times before flooding range from 48 hours at 0°C to 17 hours at 35°C. Between 5°C and 20°C this interval can be reduced to 24 hours if the ship remains at rest afloat for at least 2–3 days afterwards.
7. Can Intersleek 1100SR be overcoated with itself after immersion?
Yes. It may be overcoated by itself either when fresh or after prolonged immersion, provided the surface is in good, clean condition.
8. Does the product contain organotin biocides?
No. The product does not contain organotin compounds acting as biocides and complies with IMO document AFS/CONF/26 on harmful anti-fouling systems.
9. What should I use to clean spray equipment?
Use International GTA007 or GTA822 to thoroughly flush and clean all application equipment. Do not allow the material to remain in hoses, guns or spray equipment.
10. How should mixed units be handled during work stoppages?
Once mixed, units should not be resealed. After prolonged stoppages, it is advised to recommence work with freshly mixed units and to respect the specified pot life at the prevailing temperature.

Section 8 – Individual protection measures
The following personal protection guidance is taken from the Safety Data Sheet for Intersleek 1100SR Part A. Selection of equipment must be based on a risk assessment and compliant with local regulations.
- Engineering controls:
- Use only with adequate ventilation.
- Use process enclosures or local exhaust ventilation to keep airborne contaminants below recommended or statutory limits and below lower explosive limits.
- Use explosion-proof ventilation equipment.
- Hygiene measures:
- Wash hands, forearms and face thoroughly after handling and before eating, smoking or using the lavatory.
- Remove contaminated clothing and wash before reuse.
- Ensure eyewash stations and safety showers are close to the work area.
- Eye and face protection:
- Wear safety eyewear complying with an approved standard when a risk assessment indicates potential exposure to liquid splashes, mists, gases or dusts.
- Where contact is possible, use safety glasses with side shields unless a higher level of protection is indicated.
- Hand protection:
- Wear chemical-resistant, impervious gloves complying with an approved standard whenever handling the product if indicated by the risk assessment.
- For prolonged or frequently repeated contact: use gloves with protection class 6 (breakthrough time > 480 min according to EN374). Recommended materials: Viton or nitrile, thickness ≥ 0.38 mm.
- For brief contact: use gloves with protection class 2 or higher (breakthrough time > 30 min according to EN374). Recommended material: nitrile, thickness ≥ 0.12 mm.
- Replace gloves regularly and if any damage or degradation is observed.
- Body and skin protection:
- Select protective clothing based on the task and risks, and have choices approved by a specialist before use.
- Where there is a risk of ignition from static electricity, wear anti-static protective clothing such as anti-static overalls, boots and gloves (see EN 1149 for requirements).
- Use appropriate footwear and any additional protective measures as required by the risk assessment.
- Respiratory protection:
- Based on the hazard and potential exposure, select a respirator that meets the appropriate standard or certification.
- Respirators must be used within a formal respiratory protection program to ensure correct fit and training.
- Dry sanding, flame cutting or welding of the dry film will produce dust and/or hazardous fumes; wet sanding/flatting is preferred where possible.
- If adequate local exhaust ventilation cannot prevent exposure, wear a respirator conforming to EN140 with type A/P2 filter or better.
- Environmental exposure controls:
- Emissions from ventilation or process equipment must be checked for compliance with environmental legislation.
- Where required, install fume scrubbers, filters or process modifications to reduce emissions to acceptable levels.
