Shellac is not a single, uniform commodity product; it is a versatile and complex family of natural resins with diverse properties tailored for specific industrial applications. As a leading global shellac supplier in India since 1980, SK Shellac manufactures a complete range of lac products to meet the varied and demanding needs of global industry, from pharma to
furniture. However, navigating this variety of grades, colors, and forms can be daunting for a procurement officer, product manager, or R&D chemist trying to find the perfect match for a new formulation. This master guide is designed to help you simplify the process of choosing the right shellac resin from the complete SK Shellac product catalogue.
Step 1: Define Your Industry & Application
Your end-use is the primary filter for narrowing down your options and determining the necessary quality standards.
- Food & Pharma: You absolutely need high-purity, food-grade (E904) or pharmacopoeial-grade (USP/EP/BP) products that meet strict regulatory standards for purity and safety.
- Cosmetics: You need refined, safe, and likely light-colored or bleached grades for formulations like mascara, hairspray, or nail polish, where color and safety are paramount.
- Wood Finishing: Your choice depends on the desired aesthetic (e.g., antique restoration vs. modern light wood finish) and your application method (e.g., spraying in a booth vs. traditional hand French polishing).
- Industrial (Inks, Electrical, Abrasives): Technical specifications will be your primary guide. Factors like acid value, flow rate, polymerization time, and wax content will dictate performance in your specific process.
Step 2: Waxy vs. Dewaxed?
This is the most critical technical decision you will make, affecting compatibility and clarity.
- Choose DEWAXED if: You need a crystal-clear transparent finish, you are coating food or pharmaceutical products, you are using shellac as a sealer or barrier coat under another type of finish (like polyurethane or lacquer), or you need maximum water resistance in the final film.
- Relevant SK Shellac Products: Dewaxed Shellac Flakes (available in various colors), Dewaxed Bleached Shellac.
- Choose WAXY (Standard) if: You are doing traditional French polishing and want the lubrication the wax provides, you want a finish with a softer or satiny sheen, you are in an industrial application where wax is tolerable or even beneficial (e.g., some grinding wheels or sealing wax), or cost is a primary driver and clarity is not critical.
- Relevant SK Shellac Products: Lemon/Orange/Garnet Machine-Made Flakes, Hand-Made Flakes, Button Lac, Seedlac.
Step 3: Choose Your Color
Colour choice is primarily aesthetic for wood and cosmetics, but it also indicates the level of refining and processing the product has undergone.
- Clear/Colourless: Dewaxed Bleached Shellac (“Bone Dry”) – for no color change.
- Pale/Light Blonde: Platina or Super Blonde Dewaxed Flakes – for the lightest natural tint.
- Warm Yellow/Gold: Lemon Shellac Flakes (Waxy or Dewaxed) – for a warm, golden glow.
- Rich Amber/Orange: Orange Shellac Flakes, Standard Seedlac – the classic shellac look.
- Deep Red-Brown: Garnet Shellac, some darker Button Lacs – for depth and rich color.
Step 4: Specialized Forms
● Seedlac & Sticklac: These are raw materials. Buy these only if you have your own in-house processing and refining capabilities.
● Aleuritic Acid: This is a chemical building block, not a resin for coating. Buy this only for chemical synthesis applications (e.g., perfumery or agrochemicals).
