Hempel Infinity Silic One Recharger Treatment - 2.4 Litre

Hempel’s Infinity 77505 is a water-based maintenance coating for recharging sound Hempel’s Silic One 77450 or Hempasil Pro 87850 fouling-release systems below the waterline. It extends the performance of the existing silicone coating for a further season without requiring a complete Silic One repaint. The theoretical coverage is 8.9m² per litre, commonly rounded to 9m² per litre.

Hempel’s Infinity is intended exclusively for previously applied Hempel silicone fouling-release coatings that remain in good condition. It is not a standalone antifouling, must not be applied directly to an uncoated hull and should not be used over incompatible antifouling systems.

The transparent, water-based treatment is applied by brush or roller across the entire underwater surface. It provides a simplified seasonal maintenance option without sanding, masking or applying a conventional replacement coat of Hempel’s Silic One.

Before application, remove oil, grease and other contamination using a suitable detergent. The existing coating must be clean, dry and sound. Any repairs to the silicone coating must be completed at least 24 hours, but no more than one month, before applying Hempel’s Infinity.

Stir the product thoroughly and apply it liberally by brush or roller, ensuring the complete underwater area and previous coating are covered. Allow the treatment to infuse into the existing coating for at least 24 hours, or 48 hours at temperatures below 10°C, then rinse the surface with fresh water. The minimum time to immersion is 24 hours at 20°C, while the maximum time before immersion is one month.

5. Confirm that the surface temperature is at least 3°C above the dew point.
6. Apply only when relative humidity is below 85%.
7. Stir Hempel’s Infinity thoroughly before use.
8. Apply liberally by brush or roller over the complete underwater surface.
9. Ensure that the existing silicone coating is fully covered.
10. Allow the product to infuse for at least 24 hours, or 48 hours below 10°C.
11. Hose the treated surface with fresh water.
12. Observe a minimum immersion time of 24 hours at 20°C.

Hempel specifies fresh water for thinning and cleaning. No subsequent coating is required over Hempel’s Infinity.

Frequently Asked Questions

What is Hempel’s Infinity 77505 used for?
It is used to recharge the performance of an existing Hempel’s Silic One or Hempasil Pro fouling-release coating for a further season without applying a complete replacement coat of Silic One.

Is Hempel’s Infinity an antifouling paint?
It is a maintenance recharger for compatible Hempel silicone fouling-release systems. It is not a standalone coating system for bare or uncoated hulls.

Which coatings are compatible with Hempel’s Infinity?
The specified previous coatings are Hempel’s Silic One 77450 and Hempasil Pro 87850. The existing coating must be in good condition.

Can Hempel’s Infinity be applied over conventional antifouling?
No. Hempel specifies that Infinity should only be applied over sound Hempel’s Silic One or Hempasil Pro coatings.

Can it be applied directly to an uncoated hull?
No. Hempel’s Infinity is not intended for uncoated surfaces.

Does the existing coating need to be sanded?
No sanding or masking is specified when the compatible existing silicone coating is sound. The surface must still be cleaned, dried and checked for damage before treatment.

How is Hempel’s Infinity applied?
Stir it thoroughly and apply it liberally by brush or roller across the complete underwater area.

How much area does one litre cover?
The theoretical spreading rate is 8.9m² per litre at the specified 20-micron dry film thickness. This is commonly stated as approximately 9m² per litre.

How long must Infinity remain on the coating before rinsing?
Allow at least 24 hours for the product to infuse into the previous coating. At temperatures below 10°C, allow at least 48 hours before rinsing with fresh water.

How long should I wait before launching the boat?
The minimum time to immersion is 24 hours at 20°C. The maximum stated time before immersion is one month.

What should be used to thin the product or clean tools?
Hempel specifies fresh water as both the thinner and cleaner.

Can another coating be applied over Hempel’s Infinity?
No subsequent coat is specified. Infinity is rinsed with fresh water after the required infusion period.

What are the surface-drying times?
The stated surface-drying times are approximately eight hours at 10°C, four hours at 20°C and two hours at 30°C.
