Introduction

100% pure silicone high-performance non-toxic non-stick antifouling based on "PPG HydroReset" technology

Key properties

• Excellent antifouling performance and self-cleaning ability.
• Resists fouling by algae and slime, and even if fouled, is easily cleaned.
• Reduces fuel consumption of vessels.
• Continuous surface self-cleaning and regeneration, providing long-lasting and efficient antifouling performance.
• High volume solids.
• Helps reduce environmental impact.
• Can be used for newbuildings, dry-dock refurbishment and maintenance.
• The antifouling performance of this silicone coating lasts for more than 90 months.

Colour and gloss

• Red-brown, dark blue and black (other colours available to order).
• Gloss.

Basic data 20 °C (68 °F)

Parameters after mixing

Maximum 146.0 g/L (approx. 1.2 lb/gal) (theoretical calculated value).

Curing agent: at least 36 months, stored in a dry and cool environment.

Notes

• See supplementary parameters — recoat interval table.

Recommended substrate condition and temperature

Substrate condition

• For newbuildings or locally blasted/fully white-metal surface preparation, the biocide-free fouling release antifouling 2390 can only be applied over the dedicated tie coat, i.e. the biocide-free fouling release antifouling intermediate coat 790.
• When used as the topcoat for a full refurbishment, non-toxic non-stick antifouling 2390 may be applied over surfaces coated with non-toxic non-stick antifouling 2390, non-toxic non-stick antifouling 990 or non-toxic non-stick antifouling 890, but application shall follow the special coating application procedures recommended by PPG Protective & Marine Coatings.
• The previous coat must be clean, dry and free of all contaminants.

Substrate temperature and application conditions

• During application and curing, the substrate temperature must be above 5 °C (41 °F).
• During application and curing, the substrate temperature must be at least 3 °C (5 °F) above the dew point.
• During application and curing, the ambient relative humidity should be controlled between 40% and 85%.

Coating system specification

• To ensure the non-toxic non-stick antifouling system achieves optimum performance, apply each coat of non-toxic non-stick antifouling in strict accordance with the minimum specified dry film thickness and the special application procedures recommended by PPG Protective & Marine Coatings (PPG Industrial and Marine Coatings). Contact PPG Protective & Marine Coatings (PPG Industrial and Marine Coatings) for further details on application procedures.

This process consolidates methods that have been gradually formed and proven effective in actual use worldwide; on this basis, we have integrated and optimised them to ensure ideal application process and coating quality.

Instructions for use

Volume mixing ratio: base : curing agent = 4:1

• Open the container only immediately before use.
• Stir the base thoroughly for 5 minutes before mixing.
• After adding the curing agent, continue stirring thoroughly for at least 5 minutes.
• To prevent cross-contamination, all application equipment must be thoroughly cleaned before using this product and before resuming normal application of other materials.
• Spray mist generated when spraying biocide-free fouling release antifouling 2390 should be avoided as far as possible from contaminating other
