Application

This is a mounting medium (contains 45% acrylic resin and 55% xylenes), used in microscopy. It is an adhesive and specimen preservative that can be used manually and in automated coverslipping equipment. Special purpose adhesive and sealant for use with glass, non plastic and other non-reactive materials. It spreads quickly and evenly without forming any air bubbles.

Physical properties

Fast-drying (20 minutes), Refractive index close to that of glass (1.510), chemically neutral, little sensitivity to water, no reaction to staining, temperature limits: 42°C-17°C, not affected by ultraviolet light, non yellowing, unaffected by cold, stays optically clear for over 10 years, can be used in place of epoxy resins for mounting petrographic thin sections, used in fluorescence dyes in bones.
