Rosin refers to a non-volatile natural resin obtained from pine tree resin through various processing methods. It is an important chemical raw material widely used in industries such as soap, papermaking, paint, and rubber.

Rosin is commonly used in hot melt, pressure-sensitive, and solvent-based adhesives as a tackifying resin to enhance initial tack and improve bonding strength. It also improves the drying properties and peel strength of water-based acrylic emulsion adhesives, with a usage amount of 6% of the total monomer content.
