Frequently Asked Questions
What is the difference between Gum Rosin WW Grade and N Grade?
The primary difference lies in the color clarity and purity. Gum Rosin WW Grade (Water White) represents a highly refined, premium tier which is lighter and clearer, ideal for applications like pale varnishes, high-grade adhesives, and clear coat printing inks. N Grade is slightly darker but retains exceptional binding and thermoplastic characteristics essential for standard industrial formulations.
What are the core technical parameters of your Gum Rosin?
Our natural organic Gum Rosin has an average softening point of 78°C (Ring & Ball method), a high acid value of ≥166 mg KOH/g, and unsaponifiable matter capped at 5% maximum. It complies with premium global specification benchmarks for chemical processes.
What is the CAS number and HSN code for industrial Gum Rosin?
The global CAS number for Gum Rosin is 8050-09-7. In India, it is categorized under HSN Code 38061010 for trade documentation and chemical regulatory validation.
What are the primary applications of Gum Rosin WW Grade & N Grade?
Gum Rosin is widely utilized as a tackifier in hot-melt and pressure-sensitive adhesives, an ingredient in paper sizing agents to control fluid absorption, a vehicle intermediate in printing inks, an emulsifier in synthetic rubber production, and a binder in specialized paint or varnish formulas.
Is Gum Rosin hazardous, and what are its storage recommendations?
Gum Rosin is a natural product and is generally safe, though it can cause skin sensitization or dust irritation under heavy exposure. It should be stored in a cool, well-ventilated warehouse away from direct sunlight, open flames, and heat sources to prevent agglomeration or melting.
