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 (1.41∼1.51) is possible.

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 1.41 to 1.51 is possible.
