Product Benefits • UV fluorescence for in-process inspection • Color changes from blue to clear after UV exposure for process verification • 100% solid system (no solvents) • Excellent adhesion to a variety of surfaces • Excellent environmental resistance • Good gap filling properties • No shrinkage due to solvent evaporation • Rapid room temperature cure Typical Properties (Uncured) Typical Properties (Cured) General Information This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials. For safe handling information on this product, consult the Material Safety Data Sheet (MSDS). Factors Affecting UV Curing • Dark surfaces lengthen cure time. • Full range (UV-A, B & C) lamps provide faster cures than filtered sources. • All UV sources degrade with use. Check output with a radiometer. • Thicker films require longer cures. • Light intensity decreases as distance from UV source increases. • Some clear plastics may contain UV inhibitors.
