The BL Series is an adhesive made of PSQ (Polysilsesquioxane) and has the following characteristics.

-Characteristics
・High transparency like glass and silicone, and resistance to thermal yellowing.
・Higher adhesive strength than silicone.
・No bleeding out of the low-molecular-weight siloxane
・Good dispensing performance
・Wide range of control of the refractive index (1.40~1.54) is possible.

PSQ has a chemical structure between silicone and glass. As a result, PSQ has high transparency. In addition, PSQ has moderate hardness, making it an excellent adhesive.

PSQ is a unique material that combines the high transparency of silicone with the high bonding strength of epoxy.

PSQ's superior structural stability prevents yellowing caused by heating better than general silicone.

Lintec's PSQ has a controllable refractive index. Any design within the range of 1.40 to 1.54 is possible.

PSQ has a proven track record for fixing LED elements.　Its high adhesive strength is suitable for fixing small chips and contributes to improved device reliability. Its high transparency also contributes to improved brightness.
