Customers who make spray adhesives often ask me: What rosin resin should I use to increase the initial tackiness of my spray adhesive? I highly recommend Yoshida Premium Rosin. Its molecular structure contains a large number of carboxyl groups that can chemically react with the resins in the adhesive. This enhances the adhesive's initial tackiness, improves adhesion and drying speed, while also improving the rheology and stability of the adhesive solution. Blending rosin with SBS, SIS, petroleum resins, terpenoid resins, and other products can create exceptionally high-quality spray adhesives. Why not give it a try? Follow me to learn more about rosin!
