Use Instructions

Dispense onto/into parts to be gasketed, sealed or damped and expose to UV light in 325-380nM range. The intensity required depends on whether the EMCAST FIPG 1850 gasket is exposed directly to the UV light, or receives the radiation through a transparent medium. Start with 4,000-6,000mjoules of energy and adjust up or down as necessary.

For long term storage store in refrigerator, for day to day use, room temperatures is sufficient.

Good housekeeping rules are always important. Provide ample ventilation in all areas of handling, mixing and use. Avoid prolonged breathing of possible fumes. Minimize skin contact. Use of goggles, rubber gloves, and protective creams is recommended. Always wash exposed areas immediately using warm water and soap followed by rinsing with clear water. If material comes In contact with eyes, flush with clear water for fifteen minutes and consult a physician immediately.
