hiilivetyhartsi
Hiilivetyhartsi, in Finnish, refers to hydrocarbon resin, a family of tackifying resins derived from petroleum hydrocarbon streams such as the C5 and C9 fractions. These resins are used to modify tack, viscosity, and adhesion in a wide range of adhesive and coating formulations, including hot-melt adhesives, pressure-sensitive adhesives, rubber compounds, inks, and coatings.
Manufacture typically involves polymerization of C5 or C9 olefins, often followed by partial hydrogenation to control
Hydrocarbon resins are generally non-polar and soluble in hydrocarbon solvents. They tend to have low to moderate
Applications include modifying the tack and Peel strength of hot-melt adhesives, improving adhesion in rubber compounding,
Safety and handling follow standard industrial practices for bulk chemical resins. Exposure can cause skin or
