UV-1 Application scenarios

1. Polyurethane (PU) Products:

Used in PU foam materials (sponges), shoe materials, leather, sheets, and coatings, improving UV aging resistance and anti-yellowing performance, suitable for high-temperature PU processing applications.

2. Epoxy Resin Systems:

Suitable for LED encapsulation adhesives, chip potting compounds, transparent epoxy adhesives, and crystal clear resins, inhibiting yellowing during high-temperature curing and outdoor use, maintaining high light transmittance.

3. High-End Coatings and Adhesives:

Applied to automotive clear coats, industrial floor coatings, and epoxy adhesives, reducing color difference changes during outdoor use and extending the service life of components.

4. Rubber Products:

Used in various rubber products to delay aging, cracking, and fading caused by ultraviolet radiation, maintaining physical properties such as tensile strength and elasticity.

5. Synthetic Fibers and Outdoor Textiles:

Added to synthetic fibers such as polyester and nylon, as well as sunshades, tents, and outdoor clothing, to improve light stability and maintain appearance and performance.

6. Electronics and Specialty Materials:

Used in polymer encapsulation materials for electronic components and special transparent materials that require UV and thermal stability, ensuring long-term reliability.

UV-1 使用方法

紫外线吸收剂 UV-1(101)是一种液态甲基丙烯酸苯酯紫外线吸收剂,能吸收 280-350 纳米的紫外线,吸收峰值为 308 纳米。300-330 纳米的紫外线几乎完全被吸收。

它具有相容性好、挥发性低、热稳定性好和吸收效率高等特点,易溶于聚酯多元醇、聚醚多元醇、环氧树脂和异氰酸酯。适用于粘合剂、灌封胶、滴晶胶,尤其适用于聚氨酯、硬质泡沫、软质泡沫、粘合剂、弹性体、织物涂料、聚氯乙烯、丙烯酸树脂。一般用量为 0.3-0.5%。

适用于:聚氨酯产品,如微孔泡沫、传统硬质泡沫、半硬质泡沫、软质泡沫、织物涂层、某些粘合剂、密封剂和弹性体,以及聚氯乙烯、丙烯酸树脂和其他具有优异光稳定性能的聚合物。
