WB-23 COB Dam Adhesive
WB-23 is a single-component, heat-curing white silicone rubber material. This product offers good adhesion and moderate strength. Due to its high thixotropy, it can form ideal dam shapes via dispensing. It features moisture resistance, water resistance, ozone resistance, radiation resistance, weather aging resistance, and good high-temperature resistance. After heat curing, it exhibits good adhesion to epoxy resin, glass, and metal substrates, and has good compatibility and adhesion with COB integrated packaging materials (such as encapsulating silicone).
Features:
- Used for COB dam encapsulation of LED surface light sources, capable of forming ideal dam shapes (forms well on both PCB and aluminum substrates).
- Used for internal bonding of PTC thermistors, and bonding of electronic, electrical, and instrument components.
- Used for bonding, encapsulating, and fixing various electronic components.
