FAQ
Q1: What is the difference between addition and condensation curing potting compound?
A1: Addition curing type has faster curing speed and lower shrinkage rate, suitable for high-precision electronic component potting; condensation curing type is cost-effective with stable performance, suitable for general electronic component encapsulation.
Q2: How to store unused Silicone Potting Compound?
A2: Seal Component A and B separately and store in a cool and dry environment. The mixed adhesive must be used up at one time to avoid material waste caused by spontaneous curing.
Q3: What if the colloid is layered after long-term storage?
A3: This is a normal physical phenomenon of silicone materials. Just fully stir the colloid before use, and the product performance will not be affected at all.
Q4: Is Silicone Potting Compound a hazardous material for transportation?
A4: It is a non-hazardous material, complying with international transportation standards, but avoid contact with mouth and eyes during use; if accidental contact occurs, rinse with clean water immediately, and seek medical treatment if necessary.
Q5: Is deaeration a necessary step when using the product?
A5: Deaeration is not mandatory, but it is highly recommended for high-precision component potting, which can avoid air bubbles in the cured protective layer and ensure the sealing and insulation effect of the product.
