FAQ
1. How should unopened products be stored? Do storage conditions affect performance?
Store in a light-proof, sealed environment between 5-30℃, avoiding moisture, corrosive gases, and direct sunlight. High temperatures may cause premature cross-linking, while low temperatures may cause crystallization. Shelf life is 6-12 months; if past the expiration date, it is recommended to test the product first.
2. What is the temperature range after curing? Will performance degrade with long-term use?
The standard version withstands -40~120℃, while the high-temperature version can withstand over 200℃. Performance is stable within the rated range; exceeding the range may cause softening, deformation, and decreased strength.
3. How significant is the impact of air bubbles during use? How to resolve this?
Air bubbles reduce strength, damage appearance, and affect insulation. Vacuum degassing can be performed, selecting a low-viscosity model, or slow pouring and avoiding vigorous stirring to reduce air bubbles.
4. Can colors and hardness be customized? What information is required? How long does the lead time take?
Customization is available. Please provide color chart/color number, hardness index (e.g., Shore hardness), application scenario, and any special requirements. Simple adjustments take 7-15 working days, complex formulations take 20-30 working days.
5. What precautions should be taken for large-area application?
Control ambient temperature to 15-25℃ and humidity ≤75%; the substrate must be clean, flat, and dry; apply a single coat of 0.2-0.5mm, thicker coats can be applied in multiple layers; proper curing is essential after application.
6. Is there after-sales support for any problems encountered during use? What are the methods and response times?
Yes, there is support. Consultations can be made by phone/email/online, with a response within 30 minutes (phone/online) or 2 hours (email); complex issues will be addressed on-site within 1-3 working days (1-2 days later for remote areas); follow-up visits are available for bulk purchases.
