AFA

Aromatic-Free Acrylic Coating

AFA is an acrylic conformal coating formulated without the use of hazardous aromatic solvents. It has been

designed for the protection of electronic circuitry and meets the requirements of many industry standards. AFA

is also UL approved, achieving flame retardancy to UL94 V-0.

 Transparent coating with excellent clarity and UV resistance; ideal for LED applications

 Reduces operational hazardous; free from aromatic solvents such as Toluene and Xylene

 Fast touch dry time at room temperature for efficient coating application

 Ideal for applications requiring rework; can be removed using Electrolube ULS

Page 4 Spraying - Aerosol When applying AFA care must be taken to ensure the can is not shaken before use. Shaking the can will introduce excessive air bubbles and will give a poor coating finish. The can should be held at 45°, and 200mm from the substrate to be coated. The valve should then be depressed when the can is pointing slightly off target and moved at about 100 mm/s across the target.
