Loctite GC 10 – Halogen-free Solder Paste

Listed price may vary by MOQ. Please contact us for the best price.


Loctite GC 10 is a halogen free, zero halogens added, no-clean, low voiding, Pb-free solder paste specially formulated to provide added long term stability over a wide range of temperature conditions. The enhanced paste stability created through its novel formulation strategy increases both field application yields and on-line paste utilization.

Loctite GC 10 also shows excellent solderability when reflowed in both air and nitrogen across a wide range of challenging surface finishes and component metallizations including immersion Ag, OSP-Cu, ENIG and CuNiZn. It supports excellent reflow to overcome industry wide HiP and NWO challenges. The new flux chemistry protects the solder joint longer, improves coalescence and optimizes wetting performance, allowing for very shiny solder joints.

Loctite GC 10 is suitable for use with industry standard SAC alloys.
