K90 is a type of acrylic polymer that has a wide variety of uses. It is known for its durability, weather resistance, and UV stability, which makes it ideal for outdoor applications. Here are some common uses for K90:
1. Adhesives and sealants - K90 can be used as a base for adhesives and sealants that require strong bonding properties. The polymer has excellent adhesive characteristics and can be used in a range of industrial applications.
2. Paints and coatings - K90 is often used in paints and coatings because of its superior weatherability and UV resistance. It prevents the paint from fading or cracking under harsh weather conditions.
3.Povidone is widely used in pharmaceuticals, mainly in solid preparations. In tablets, povidone solution acts as a viscosity agent in wet granulation.
Povidone powder can also be added directly to other powders in dry form, mixed, and then added with water, alcohol or hydroalcoholic solution for granulation.
4.In gastrointestinal or parenteral drugs, povidone acts as a solubilizer to accelerate the dissolution of poorly soluble drugs from solid dosage forms. Povidone solutions can also be used as coating materials.
In addition, povidone also contains suspending agents, stabilizers or viscosity-increasing agents in some topical and oral suspensions and solutions. The solubility of many poorly soluble drugs increases when mixed with povidone.
