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