how to use

How to use
1. Cleaning of target surface: When surface cleaning is necessary, use an appropriate solvent to remove oil and debris on the surface.
2. Static electricity and dust removal: Treat the surface using an air shower or ionizer to prevent dust collection or static electricity on the surface.
3. Residual contaminants may result in defective film exterior and adhesion.
4. UV-curing conditions
A UV lamp is either an electrode type or no electrode type. For an electrode-type UV lamp, a metal halide lamp or a high-voltage mercury lamp is recommended.
More superior surface and film exterior can be achieved when nitrogen reflux is possible within the UV curing device.
If the light is not intense enough, surface tack may occur or steaming or defective adhesion may result at high temperature.
Remarks
1. It contains substances harmful to skin and body. Wear a mask and protective gears prior to work. (For more details, refer to the MSDS.)
2. The product may deteriorate if exposed to natural light including sunlight, UV light (UV lamp), and work light (fluorescent light and incandescent light).
3. There is a possibility of deterioration or volume expansion when stored at above 30 ℃ for a long period of time.
4. Please use the product within its shelf life (12 months from the manufacturing date). There is a possibility of deterioration, precipitation, etc. when the product is stored for a long period of time. Please inquire the customer service center if you want to use a product that has been stored for a long time.
