PROTECTION COATINGS

P

PRE-PAINTED HYDROPHOBIC COATING

Description:
The hydrophobic coating gives the drops of water wetting the fin a spheroid shape (contact angle > 50°) for easier draining.

Technical data:
• Aluminum fin made of 8079 alloy (EN 573-3) pre-painted with polyester lacquer.
• Corrosion resistance: 1000 hours (ASTM B117). 

L

PRE-PAINTED HYDROPHILIC COATING

Description:
The " hydrophilic " coating, with high surface tension in other words, gives the drops of water wetting the fin a flattened shape (contact angle < 15°). These conditions favour circulation and the adiabatic saturation of the air between the fins with notable heat exchange benefits.

Technical data:
• Aluminum fin made of 8079 alloy (EN 573-3) pre-painted with hydrophobic lacquer.
• Corrosion resistance: 250 hours (ASTM B117). 

THERMOGUARD®

• Polyurethane based coating.
• High flexible properties.
• Heat conduction and UV resistant properties.
• Prevents chemical and galvanic corrosion.
• Corrosion resistance (ASTM B117): 3000 hours.

BLYGOLD®

• Heat conductive pigmentation.
• Very high chemical resistance at a low layer thickness.
• Corrosion resistance (ASTM B117): 4000 hours.

HERESITE®

• Suitable for marine and salt air environments.
• Withstand exposure to an extensive variety of corrosive and chemical fumes.
• Corrosion resistance (ASTM B117): 6.000 hours.

ELECTROFIN®

• Water-based, flexible cationic epoxy polymer using an electro-coat process.
• It guarantees complete heat exchanger coverage.
• Corrosion resistance (ASTM B117): 6.000 hours.
• C5M & C5I High Durability (ISO 12944).
