Neutral (dealcoholized) sealing silicone rubber 549
Luxbond549 is a one-component, translucent, room temperature curing neutral (de-alcohol) silicone rubber. This can be used for component protection and shallow potting, suitable for sealing and bonding of polycarbonate, general plastics, glass, metal, ceramics and other materials. This can absorb moisture from the air at room temperature to cure and form a soft rubber layer, which has excellent adaptability to high and low temperatures, and can maintain good elasticity between50-200°C.
