PCB temporary masking

【Summary】 STS-UV5082 is a UV curing peelable adhesive for long time protection of deep holes/slots in PCBs, suitable for long time temporary protection of PCB/component holes/slots to ensure that the holes/slots are free from the erosion of chemicals and other substances during the long time & multi-processing of the circuit boards.

       STS-UV5082 is a UV curing peelable adhesive for long time protection of deep holes/slots in circuit boards. It is suitable for long time temporary protection of holes/slots in circuit boards to ensure that the holes/slots are free from the erosion of chemicals and other substances during long time & multi-processing of circuit boards. The adhesive is a viscous liquid with low TI and good flowability. After curing, it has strong adhesion to ensure long term protection. At the same time, the cured adhesive film has high cohesion and high elongation to ensure complete removal of the adhesive, and it is not easy to break the adhesive. Resistant to wet processes such as copper plating and copper plating on circuit boards (customer verified).
