Within bitumen-based sealants as well as hot‑melt roof covering techniques, C5 resin increases adhesion in order to numerous substrates, versatility, climate opposition, as well as tack—a essential mixture with regard to long‑lasting sealants as well as pulsating supplies.
Overall performance Advantages
Enhanced add as well as adhesion
The actual branched, reduced molecular pounds framework plays a role in more powerful area connections along with adhesives, rubberized, as well as films.
Improved digesting relieve
Reduce viscosity facilitates combining as well as extrusion effectiveness within polymer bonded compounding.
Energy strength
Along with conditioning factors over 100 °C, C5 resins preserve balance below warmth tension.
Visual qualities
Gentle color guarantees item openness, advantageous within product packaging as well as obvious glues.
