Methacrylic acid

Methacrylic acid

2-Methylpropenoic Acid; Methacrylate; Alpha-Methylacrylic Acid; MAA

CAS 79-41-4

Chemical Formula C4H6O2

Molecular Weight 86.09 g/mol

Methacrylic acid (MA) is a strong irritant and is corrosive because of its strong acidity. It is an alpha,beta-unsaturated monocarboxylic acid that is acrylic acid in which the hydrogen at position 2 is substituted by a methyl group. It is functionally related to an acrylic acid. It is a conjugate acid of a methacrylate.

Industrial Uses

1. Agrochemicals

  • Soil Conditioners: Methacrylic acid-based polymers are used in soil conditioning products to enhance soil structure, water retention, and nutrient availability. These conditioners help improve crop yields and reduce water consumption.
  • Pesticide Formulations: It can be used in certain pesticide formulations to improve the adherence and effectiveness of active ingredients on plant surfaces.

2. Paints & Coatings

  • Acrylic Coatings: Methacrylic acid is a critical component in the manufacture of acrylic paints and coatings. It improves the adhesion, gloss, and weather resistance of the coatings, making them suitable for automotive, architectural, and industrial applications.
  • Surface Modifiers: It is used in modifying the surface properties of paints and coatings, providing scratch resistance, improved flow, and leveling characteristics.

3. Sealants & Adhesives

  • Reactive Adhesives: Methacrylic acid is used in the formulation of reactive adhesives that require strong bonding properties. It enhances adhesion to various substrates, including metals, plastics, and glass.
  • Structural Sealants: Methacrylic acid -based sealants provide excellent durability, weather resistance, and flexibility, making them ideal for construction and automotive applications.

4. Lubricants & Automobiles

  • Viscosity Modifiers: Methacrylic acid-based polymers are used as viscosity modifiers in lubricants for automotive and industrial machinery. These modifiers improve the stability of lubricants under high temperatures and mechanical stress, reducing wear and tear on moving parts.

5. Personal Care 

  • Film Formers in Cosmetics: It is used in cosmetic formulations as a film-forming agent. It helps in providing long-lasting effects, water resistance, and smooth application in products like nail polishes, hair gels, and skin care creams.
  • pH Adjuster: In personal care products, methacrylic acid is used to adjust pH levels, helping to stabilize formulations and enhance the effectiveness of active ingredients.

6. Fabric Solutions

  • Flame Retardant Finishes: Methacrylic acid can be formulated into flame-retardant coatings for textiles used in furniture, automotive interiors, and protective clothing. These coatings help reduce the flammability of fabrics, enhancing safety in various applications.
  • Waterproofing Agents: Methacrylic acid-based resins are used in waterproofing treatments for textiles, providing water resistance without compromising the fabric's breathability or comfort.
