FAQ

What is Gum Rosin and what is it used for?

Gum Rosin (colophony) is a natural resin obtained from pine tree oleoresin, supplied in graded lumps and used across resins, paper chemicals, rubber manufacturing and Agarbatti (incense) production.

What are the major industrial applications of Gum Rosin?

It's a base material for resin manufacturing, paper sizing chemicals, rubber compounding, and incense (Agarbatti) production.

How is Gum Rosin obtained from pine trees?

It's derived from pine oleoresin — gum turpentine is the volatile fraction distilled off, and gum rosin is the non-volatile solid residue left behind.

What is the difference between Gum Rosin and Gum Turpentine?

They're co-products of the same pine oleoresin distillation — gum turpentine is the volatile liquid fraction, while gum rosin is the solid resin residue.

Which industries use Gum Rosin as a raw material?

Resin, adhesive, paper, rubber, printing ink and incense manufacturers.

What are the different grades of Gum Rosin?

Grades range from WW (lightest colour, highest clarity) through X, WG, N, M, K, D, B (darkest, lowest clarity) to an Indonesia-sourced grade — each with its own colour, softening point and acid number specification.

What properties determine the quality of Gum Rosin?

Colour and clarity, softening point (typically 65–90°C depending on grade), acid number (165–190), heat stability and solubility.

How is Gum Rosin used in adhesives and printing inks?

Its resin character provides tack and film-forming properties valued in adhesive formulations and as a binder/modifier in printing ink production.

How should Gum Rosin be stored and handled?

Keep out of direct light to limit oxidation and colour degradation, store in a cool, dry place in tightly closed containers, away from incompatible substances.

What should manufacturers consider when buying Gum Rosin in bulk?

Match the grade (WW through B, or Indonesia) to the colour/clarity requirements of the end application, and confirm softening point and acid number consistency batch to batch.

Who supplies Gum Rosin WG in bulk?

Himalaya Terpenes Pvt. Ltd. (Mumbai, India) supplies Gum Rosin WG in bulk, in drums, bags, IBCs or ISO tanks depending on the grade, for domestic and export orders. The company is an ISO 9001:2015-certified pine-chemical manufacturer operating since 1971.
