The Jiaoshuilao JSL 495 features an ultra-low viscosity of just 50mpa.s, allowing it to wick into the tightest joints and hairline cracks by capillary action. This makes it ideal for bonding close-fitting plastic and metal parts where thicker adhesives simply cannot penetrate. It is surface-insensitive, meaning it works reliably even on surfaces that have not been specially prepared. With a 12-second cure, JSL 495 is the precision instrument of the instant adhesive world — perfect when you need the glue to flow into the joint rather than sit on top.
