Recommended substrate condition and temperature

Substrate condition

• For newbuilding or spot blasting / full white-metal blasting surface preparation, biocide-free non-stick antifouling 990 can only be applied over

the surface of biocide-free non-stick antifouling intermediate coat 790.

• If for refurbishment overcoating only, provided that application follows the requirements of PPG's special application procedure general rules for biocide-free non-stick antifouling,

biocide-free non-stick antifouling 990 can be overcoated with itself or applied over the surface of biocide-free non-stick antifouling 890.

• 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 shall be maintained between 40% and 85%.

Coating system specification

• Biocide-free non-stick antifouling coating system – Coating System Information Sheet 3127
• To ensure the biocide-free non-stick antifouling system achieves the desired performance quality, when applying each coat of biocide-free non-stick antifouling, strictly comply with

Apply in accordance with the minimum specified dry film thickness and the special application process guidelines recommended by PPG Protective & Marine Coatings. Contact PPG Protective & Marine Coatings for further details on the specific application process, which has been compiled, to the best of its knowledge, from methods that have gradually formed and been proven effective in practical use around the world, and has been consolidated and optimised on this basis to ensure the ideal application process and coating quality.

Instructions for use

Mixing ratio by volume: base : curing agent = 80 : 20

• Open the container lid only immediately before use
• Stir the base thoroughly for 5 min before mixing
• After adding the hardener, continue stirring thoroughly for at least 5 min
• Do not add thinner
• To prevent cross-contamination, all application equipment must be thoroughly cleaned before using this product and before resuming normal application of other materials.
• Provide thorough masking at the application site to minimize as far as possible contamination of adjacent surfaces of other coatings not to be coated with biocide-free non-stick antifouling 990 by its spray mist.
