Product Information

ULTRAVIOLET LIGHT TECHNOLOGY

KOA products are a popular light curing adhesive that cures via long wavelength ultraviolet radiation (365 nanometers). This is a range considered safe to work with as compared to medium wavelength (UV-B) used in sun tanning or short wavelength used for germicide purposes. We do suggest the use of UV protected eyeglasses when using your ultraviolet curing lamp.

Ultraviolet light is part of our environment, found in sunlight. We do not recommend using sun-light as a source of UV energy to cure any of our KOA products. Unprotected and prolonged exposure to any form of UV light, sunlight and long wavelength can result in cataracts and possibly cancer. We suggest the use of a wavelength of 470 uW/cm² at six inches (15 cm). This type of lamp has shown to cure KOA products in two or three minutes. PLEASE TEST BEFORE BEGINNING PROJECT

APPLICATION

1. All surfaces to be bonded (glued) should be clean and dry. Do not use a cleaner containing silicone, as a film will be left.
2. Use a pattern to determine exact location of pieces to be bonded. If you are not using a pattern, check fit and location before bonding. Once bonded, the pieces are difficult to remove, the method we suggest to break the bond is via a heat source. A required temperature of approximately 270° F is      needed to soften the bond.
3. Apply a sufficient amount of KOA product to the center of one of the pieces to be bonded. Press gently until the KOA product has spread to cover the entire surface to be bonded, allow KOA product to ooze at the edges.
4. Double check to see that all pieces are in the right location, now is the time to expose KOA product to your long wavelength UV lamp for approximately two to three minutes. TEST THE TIME BEFORE STARTING.
5. Clean up with a single edged razor blade and glass cleaner.

LONG WAVELENGTH ULTRAVIOLET LIGHT CURING LAMPS

When using KEMXERT's KOA products, an ultraviolet light curing lamp emitting long wavelength (UV-A) peaking at 365 nanometers must be used to cure the UV glue and obtain adhesion. The sun is a poor substitute for UV-A energy.

We are offering, at a reasonable price, ultraviolet light curing lamps. Their practical design and ease of operation assures hours of trouble-free use. These low intensity lamps will cure our KOA products within two to three minutes.

We recommend these low intensity lamps to cure our products by the Glass Artist because of their low cost. Higher intensity lamps will cure faster but are more expensive. KOA products should be stored at a temperature range of 70-75° F in a dark place or away from an ultraviolet light source. KOA 300 has shelf life of ten months. Shelf life on all other grades is one year.
