Fine Bysacky

Fine Bysacky Seedlac is a widely used commercial grade seedlac with moderate to higher impurity levels, commonly derived from the Bysacky strain of sticklac. This grade undergoes traditional washing, filtering, and sun-drying methods that remove a portion of the dye and impurities, leaving a functional lac resin suitable for cost-effective shellac production. With a relatively high color index and broader tolerance for insoluble content, Fine Bysacky serves industries that prioritize affordability over ultra-refinement, such as wood coatings, printing inks, and basic industrial lac products.

Key Features –

  • High Tolerance Grade: Allows higher insoluble matter, making it suitable for non-critical applications.

  • Darker Shade Profile: High color index allows production of darker, richer shellac finishes.

  • Economical Input Material: Ideal for applications where raw shellac refinement cost needs to be minimized.

  • Standardized Supply Chain: Commonly available and widely accepted in both domestic and export markets.

  • Customizable Output: Suitable for tailoring into various machine or hand-made shellac grades through local processing.

Applications –

  • Shellac Manufacturing:

    • Used to produce lower- to mid-grade machine or hand-made shellac for general-purpose coatings and polishes.

  • Wood Polish & Finishes:

    • Suitable for traditional furniture polish and varnish in budget-sensitive markets.

  • Printing Inks:

    • Provides excellent binding properties in conventional ink formulations.

  • Non-Critical Industrial Coatings:

    • Used in protective lacquers for packaging, craft goods, or temporary seals.

  • Bleached Shellac (Low Purity):

    • Can be chemically processed into bleached shellac for secondary applications.

  • Agricultural & Rural Uses:

    • Sometimes used in non-industrial applications due to its affordability and availability.
