Still debating whether to use C5 high tack or C9 weather-resistant in your formula? No need to choose! C5/C9 copolymer petroleum resin combines the best of both. High tackiness, strong initial stick—sticks well and won’t peel; heat and weather resistant, anti-aging—stable even outdoors. Excellent compatibility with SBS, EVA, and rubber, no precipitation, no delamination, low odor, dissolves quickly. Suitable for hot melt adhesives, pressure-sensitive adhesives, rubber products, road marking coatings, ink modification, and more. Uniform batches, stable quality, and can even reduce formulation costs. Follow me to learn more about chemical products.
