Instruction for Use

1. Coating surface area should be clean and free of any fluxes, residues, dust or any other contaminants.

2. A UV lamp with a wavelength of 365nm is required. The UV light should be focused towards the coated surface.

3. Curing speed is determined by the intensity of UV radiation, the distance from the UV light source and the coating surface. The depth of coating material can also require additional cure time.

4. Immediately close the lid after use. A black hose must be used to dispense the adhesive.

5. This material should be stored away from sunlight, UV light and artificial light sources.
