TPU coating technology has been fully upgraded, and the new generation of hot repair film achieves rapid scratch self-healing in 30 seconds

In 2026, domestic material companies will release a new generation of TPU functional coating technology, comprehensively innovating the performance of paint protection film and color changing film products. The new hydrophobic ultra bright fast repair coating system can repair fine hair scratches in 30 seconds at 60 ℃, with a 60% increase in repair efficiency compared to traditional thermal repair products; The high anti pollution formula can resist the corrosion of markers, asphalt, and chemical cleaning agents, and there is no residue when wiped with alcohol. It has passed the special test for vehicle chemical agent corrosion. The substrate side is synchronously iterated with two mainstream thicknesses of aliphatic TPU, 8.0 ± 0.3mil and 9.0 ± 0.5mil. The yellowing resistance level covers a full gradient of 5-7 levels, and the color difference Δ E after QUV UV aging for 2000 hours is ≤ 2. The high and low temperature tolerance range is -30 ℃~110 ℃, suitable for all climatic environments in the north and south of China. The production end is equipped with 75 # high-density hydrophobic release base paper, nano hot melt adhesive to enhance adhesion stability, and high-temperature baking at 120 ℃ for 3 minutes without delamination or edge curling problems. Currently, this coating technology has been applied in bulk to the entire range of TPU film products with a warranty of 6-15 years, and is synchronously matched with a 10000 level dust-free coating production line for mass production, greatly reducing the rate of bubbles and orange peel defects in terminal construction.
