FAQ
1. What are the official testing standards and warranty period for the product's UV resistance?
It passes the UV-340 xenon arc lamp aging test, achieving level 0 yellowing resistance after 168 hours and a performance retention rate of >90% after 2000 hours. The warranty is 3 years for normal outdoor use, which can be extended to 5 years with a special coating.
2. What are the advantages in cost and performance compared to ordinary epoxy resin?
It solves the problem of yellowing in traditional outdoor products, can replace imported weather-resistant epoxy, reduces procurement costs by more than 30%, and also reduces subsequent maintenance and replacement costs.
3. What are the mixing ratio and operating window during construction?
The weight/volume mixing ratio is mostly 100:50. The applicable period at 25℃ is 40-90 minutes. It is recommended to complete construction within this period to ensure uniform and stable curing.
4. Can it be mixed with pigments and fillers? Will it affect the UV resistance?
Compatible with common additives such as acrylic pigments; recommended addition level not exceeding 5%. The specialized formula minimizes the impact of fillers on UV resistance, maintaining core protective effects even after mixing.
5. Are special treatments required for different substrates before application?
Metal substrates require degreasing and rust removal. Plastic substrates are recommended to be lightly sanded. Stone and wood substrates require a moisture content of <8%. No additional special treatment is required; it is highly versatile.
6. What are the storage conditions and shelf life for bulk purchases?
Components A and B should be sealed separately and stored in a dry, cool place at 5-30℃, avoiding direct sunlight. Unopened, the shelf life is 12 months; once opened, it is recommended to use within 3 months.
