What is ester of rosin?

Ester of rosin is a synthetic resin derived from rosin, which is a natural resin obtained from pine trees. It is commonly used in adhesives, sealing compounds, inks, and coatings due to its tackiness, good adhesiveness, and excellent resistance to oxidation and weathering.

Ester of rosin is produced by reacting rosin with alcohol or glycerol under controlled conditions. This process results in a product that has a lower melting point and improved solubility compared to natural rosin.

Ester of rosin is often used as a tackifier in pressure-sensitive adhesives, where it helps improve adhesion to various substrates. It is also used in hot melt adhesives, where it helps improve the flexibility and tackiness of the adhesive.

Overall, ester of rosin is a versatile resin that offers excellent adhesion properties and is widely used in various industrial applications.
