Handling, Application, Storage

I. Precautionary Information

Refer to product label and Safety Data Sheet (SDS) for health and safety information before using this product.

II. Instructions for Use

A. Surface Preparation

A thoroughly cleaned, dry, grease-free surface is essential for maximum performance. For repeatable

behavior and results the material and the substrates should be in the range of 68-77°F (20-25°C) object

temperature. Caution: Use adequate respiratory, eye and skin protection when using etch solutions.

B. Film Application

Care must be taken when handling AF 3074 FST at low temperatures because it can easily crack. Warm

AF 3074 FST to ambient conditions in the sealed package to prevent moisture condensation on the

adhesive surface.

1. Cut portion of film to be used with protective liners in place

2. Remove liner from one side of the film.

3. Place film using the remaining liner as a protective cover.

4. Avoid air entrapments between film and the surface. On metal surfaces, for example, the film

can be rolled into position with a rubber roller

5. Remove second protective liner

6. Assemble parts and cure
