Hydrophilic aluminium finstock is commonly selected for air-conditioning and refrigeration heat exchangers where a functional surface coating is required as part of the fin specification.

For coated or hydrophilic finstock requirements, buyers should provide information including:

• Required aluminium alloy

• Coating type

• Coating specification

• Coating on one or both sides

• Required temper

• Thickness

• Width

• End-use application

• Required performance specification

The exact coating system should be confirmed during the technical quotation process rather than assumed from the base alloy alone.
