Application:
Coating of tablets, granules, and pills: It is one of the most important functional pharmaceutical excipients in modern pharmaceutical preparations.
- Moisture-proof and light-proof. Maintain drug stability in tropical environments. Orally resistant to gastric acid (liquid) to delay intestinal release.
- Separate porous tablet cores and hygroscopic tablet core openings to isolate incompatible ingredients
- Granulation can be used as a matrix material to increase the coating weight and delay the release of drugs.
Cosmetic Film Former: Blended into color cosmetics, nail polishes, sunscreens, and hair styling formulations as a reliable setting and film-forming modifier, granting end products superior water-resistance, sweat-proofing, and high-gloss aesthetics.
Specialty Coatings & Adhesives: Utilized across heavy industries to manufacture pressure-sensitive adhesives, high-spec automotive finishes, and textile treatment modifiers to boost substrate weatherability and bonding tenacity.
Storage
Must be stored in a cool, dry, and exceptionally well-ventilated warehouse, with recommended storage temperatures strictly maintained below 25°C. Keep containers hermetically sealed and thoroughly protected from moisture and ambient heat sources. Keep away from open flames and powerful oxidizers.
