What is INTERFINE 1080 and why choose it
INTERFINE 1080 from International Marina is a high performance, single pack acrylic polysiloxane finish coat based on patented technology. It is formulated with low VOC levels and contains no free isocyanates. Designed primarily as a brush and roller applied maintenance finish, it delivers a durable, UV resistant, high gloss cosmetic appearance on suitably primed steelwork in demanding onshore and offshore environments.
This finish coat is ideal where long-term aesthetics are important on structures such as tank externals, pipelines and structural supports, providing a high standard decorative appearance while working as part of an anti-corrosive coating system.

Applications and use cases
Typical environments
- Offshore (marine) environments: Ideal for exposed steelwork such as tank externals, topside structures and pipework where UV resistance and appearance are important.
- Onshore industrial sites: Suitable for structural steel, tank externals, pipe racks and supports requiring a durable, decorative finish as part of a protective coating system.
Recommended substrate and systems
- Applied as a finish coat over approved anti-corrosive primers and intermediates (such as Devran, Intercure, Intergard, Interplus and Interzone systems, where specified).
- Suitable for maintenance overcoating of tightly adherent aged coatings after appropriate surface cleaning and preparation.
- For dark primers or intermediates and certain colours, two coats may be required to achieve uniform coverage.
Application methods on site
- Brush and roller: Primary application methods, especially for maintenance and touch-up work.

FAQ
-
Is INTERFINE 1080 a single pack or two pack coating?
INTERFINE 1080 is a single pack acrylic polysiloxane finish coat. It should be mixed thoroughly with a power agitator before application.
-
Which application methods are recommended?
The product is primarily designed for brush and roller application. Airless and conventional air spray are also suitable when the correct wet film thickness and equipment settings are used.
-
Can INTERFINE 1080 be used as a stand-alone anti-corrosive coating?
No. It should always be applied over a recommended anti-corrosive coating scheme on properly prepared and primed surfaces.
-
Is the coating suitable for immersion service?
No. INTERFINE 1080 is not recommended for use in immersion conditions.
-
How does relative humidity affect drying?
Drying times are influenced by relative humidity. Higher relative humidity accelerates drying. Published drying times are based on 50% relative humidity at the stated temperatures.
-
What surface preparation is required before application?
Surfaces must be clean, dry and free from contamination, prepared in accordance with ISO 8504:2000. Damaged or breakdown areas should be prepared to Sa2½ / SSPC-SP6 or SSPC-SP11, then re-primed before overcoating.
-
Which thinners can be used?
Only recommended International thinners should be used, specifically International GTA007 (or GTA028 in North America). Alternative thinners, especially those containing alcohols or ketones, can severely inhibit curing.
-
What is the maximum overcoating interval?
For self-overcoating, the maximum interval is typically up to 12 months, depending on temperature and conditions. Over approved primers and intermediates, the interval is product and environment specific.
-
Can it be applied over aged coatings?
Yes, it is suitable for overcoating most tightly adherent aged coatings once loose or flaking material has been removed and glossy areas lightly abraded.
-
What happens if condensation occurs during drying?
Condensation during or immediately after application may lead to a matt finish and/or colour change on the coating surface.
