FAQ
Q1: Will this silicone damage PC/ABS plastic surfaces?
A1: No, it is fully compatible with PC, PP, ABS, PVC and most metals, causing no corrosion or damage.
Q2: Can mixed silicone be stored for later use?
A2: No, the mixed adhesive must be used in one go to ensure optimal curing and performance.
Q3: How to handle stratification during storage?
A3: Simply stir the component thoroughly before use; this does not affect product performance.
Q4: Is it a hazardous material for international shipping?
A4: No, it is classified as non-hazardous, complying with global transportation regulations.
Q5: Why is curing slower in winter?
A5: Low temperatures slow the curing reaction; heating at 80–100℃ for 20 minutes ensures fast and stable curing.
