The reason why bubbles are generated after the electronic potting glue is cured

2, Solution to the second cause of bubbles：

There are several possibilities below for the reaction between moisture and curing agent

①The main agent has been used many times ,during each stirring process There is moisture mixed in. It may also be because the lid of the package is not tightly closed. In order to prove what the reason is, Please mix the base agent and hardener in a dry cup according to the above instructionsAfter deaerationand put it in the oven（60-80℃）Cure. If bubbles still occur, It means that the main agent has deteriorated at this time,Please don’t do it again Use.

②Potting products contain too much moisture, It is recommended to re-test the product after preheating it.

③The surface of the mixture of base agent and curing agent reacts with moisture in the surrounding air. If so , Please cure in a dry environment ;font-size:19px”>, “>If the product allows it, can be cured in a heated oven.

④The liquid main agent and curing agent mixture may be Exposed to other chemical substances( Such as solvents, release agents, varnishes, glues, etc.）. Make sure these substances are removed before the next test.

Weigu polyurethane electronic potting glueisa two-component polyurethane adhesive. After curing through the potting process, the components can be reduced from being affected by external environmental conditions, ensuring that the components operate well in standard working environments, and improving the normal stability and service life of the components. The potting glue has the properties of insulation, moisture-proof, dust-proof, mildew-proof, shock-proof, leakage-proof, corona-proof, corrosion-proof, salt spray-proof, acid-proof and alkali-proof, vulcanization-proof, anti-aging, high and low temperature impact resistance, high humidity and high temperature resistance, Flame retardant, environmentally friendlyetc.Superior performance. Different potting adhesive application solutions have different performance requirements, resulting in different synthetic materials and formulas as well as synthetic process methods.
