Heat Resistant Temporary Peelable Masking Glue Description
"Protect through the heat, peel off clean." This heat resistant temporary peelable masking glue (3769D) is a blue-red, silicone-free UV curing masking adhesive developed for temporary protection of PCBA electronic components during wave soldering. It reliably withstands wave soldering and reflow soldering thermal profiles, features high thixotropy for excellent stacking without slump, cures fast, and peels off easily. With a low-shrinkage formulation, 3769D keeps sensitive components safe from solder splash, flux, contamination and mechanical stress during assembly and soldering.

FAQ
Q1: What is this heat resistant masking glue mainly used for?
It is a peelable masking glue for temporary protection of PCBA electronic components during wave soldering and reflow soldering. Once protection is no longer required, it peels off easily without residue.
Q2: Can it withstand wave soldering and reflow soldering?
Yes. 3769D is formulated to remain intact and protective through both wave soldering and reflow soldering thermal profiles, then peel off cleanly afterwards.
Q3: How is it applied and cured?
It is applied by dispensing, with high thixotropy for excellent stacking and no slump, and cures rapidly under UV energy of about 400 mJ/cm².
Q4: Does it leave residue after peeling?
No. The cured mask peels off easily and cleanly, leaving no residue on the protected PCBA and electronic components.
Q5: Why is a silicone-free formulation important?
Being silicone-free prevents silicone contamination that can disturb subsequent conformal coating, bonding or soldering on the assembly, and low shrinkage minimizes stress on components.
Q6: How should it be stored and what is its shelf life?
Store sealed at 8-28°C in a cool, dark and dry place away from direct sunlight. Unopened shelf life is approximately 12 months. Available in 50g and 300g packages.
