Cautions
Store the product in a sealed container, and keep it away from children for storage.
The glue will not cure if exposed to a certain amount of the following chemicals:
Organic compounds of N, P, and S, ionic compounds of Sn, Pb, Hg, As, etc.;
Compounds containing alkyne and polyvinyl.
To avoid the above problem, Any residual rosin on the circuit board should be wiped clean when using the glue, and use soldering tin with low lead content.
This product is non-hazardous. Please consult the MSDS of the product for safety information.
