Clariant Hostavin® 3350 is a high-efficiency hindered amine light stabilizer. It can delay the aging process of polymer materials through the dual mechanisms of absorbing and quenching ultraviolet light and inhibiting the generation of free radicals. It has long-term stable protection ability, excellent compatibility with various resin systems and additives, and is suitable for high-temperature processing scenarios.
Has dual functions of UV absorption and free radical quenching, blocks the chain reaction of polymer UV aging from the source, and has outstanding protection efficiency.
Excellent long-term weather resistance, can maintain the color stability and physical and mechanical properties of plastic products for a long time, and avoid yellowing, embrittlement, cracking and other problems of materials.
Good compatibility with various engineering plastics such as polyamide, polycarbonate, polyethylene terephthalate (PET), polypropylene (PP), high-density polyethylene (HDPE), as well as coatings used for these materials.
Maintains its effectiveness under high-temperature processing conditions, and can enhance the overall thermo-oxidative stability effect when used in combination with other additives such as antioxidants.
Suitable for automotive exterior parts and electronic appliance housings made of engineering plastics such as polyamide (PA) and polycarbonate (PC), improving the weathering life of outdoor service.
Compatible with packaging films and containers made of PET and PP materials, preventing material degradation caused by UV radiation and extending the shelf life and service life of packaging products.
Applicable to HDPE pipes, sheets and other building materials products, ensuring their structural strength and appearance stability in outdoor environments exposed to sun and rain.
Used in various polymer coating systems, such as protective paints for engineering plastics and coatings for outdoor building materials, to enhance the UV aging resistance of coatings.
Suitable for the production of plastic modified masterbatches, endowing functional masterbatches with long-term light stability characteristics, and expanding the application of modified materials in photovoltaic, outdoor building materials and other fields.
