TPU hot melt adhesive anti - UV masterbatch is developed specifically to address the aging problems of TPU hot melt adhesives in harsh outdoor environments. It is a functional masterbatch that combines anti ultraviolet technology and excellent adaptability to hot melt adhesives. It uses selected weather-resistant TPU resin as the carrier to ensure high compatibility with various TPU hot melt adhesive systems. It is combined with 10% - 15% of high - efficiency anti - UV additives in total, including 5% - 8% of benzotriazole - type ultraviolet absorbers and 3% - 5% of hindered amine - type light stabilizers, and 1% - 2% of antioxidants are added for synergistic effect. It is made through a twin - screw precision extrusion and precise granulation process.
Its core advantages are reflected in two aspects: excellent outdoor weather resistance and non - destructive optimization of hot melt adhesive performance. In terms of anti-ultraviolet performance, it can effectively shield ultraviolet rays in the 280 - 400nm band. After 3000 hours of QUV accelerated aging test, the yellowing index △YI of TPU hot melt adhesive added with this masterbatch is ≤3, the tensile strength retention rate is ≥85%, and the elongation at break retention rate is ≥80%. It significantly delays the molecular chain breakage and degradation caused by ultraviolet irradiation, preventing the hot melt adhesive from becoming brittle, discolored, and losing its viscosity. When it is integrated with TPU hot melt adhesive, the masterbatch is evenly dispersed and does not affect the initial tack and final curing strength of the hot melt adhesive. It can be stably used in the conventional hot melt adhesive processing temperature range of 150 - 220℃, and the addition amount is flexible, usually 4% - 8%.
This masterbatch is widely used in outdoor building sealing, automotive parts bonding, outdoor equipment manufacturing and other fields. In the construction industry, it is used for TPU hot melt adhesives for door and window sealing and roof waterproofing, which can resist long-term sunlight exposure and maintain sealing and bonding effects. In automotive manufacturing, the TPU hot melt adhesives used for body trim strips and lamp fixing, after being modified by this masterbatch, are durable and reliable in outdoor driving environments.
