About Acrylic Acid
Acrylic Acid is a clear, colorless liquid with a sharp, acrid odor. It is an unsaturated carboxylic acid that contains both a vinyl group and a carboxylic acid group, which makes it highly reactive. Due to this dual functionality, it can undergo polymerization and esterification reactions, making it an essential building block in the production of a wide range of industrial and consumer products.
Applications / Uses
Acrylic Acid is a highly versatile monomer used across multiple industries:
- Adhesives & Sealants: Used to produce pressure-sensitive adhesives and structural bonding agents with high durability and elasticity.
- Paints & Coatings: Forms acrylate-based polymers that improve adhesion, UV resistance, and weathering performance in decorative and industrial paints.
- Superabsorbent Polymers (SAPs): A major application is in the hygiene sector — Acrylic Acid is polymerized to create SAPs used in baby diapers, adult incontinence products, and feminine hygiene items. These polymers can absorb up to several hundred times their weight in liquid.
- Textile & Leather Finishing: Functions as a component in specialty finishes, thickeners, and softeners for textiles and leather goods.
- Water Treatment: Acrylic acid-based dispersants are used to prevent scale and fouling in boilers, cooling towers, and other water systems.
- Construction Materials: Enhances performance in waterproof coatings, sealers, grouts, and other construction chemicals.
Storage & Handling
- Store in tightly closed, inhibited containers to prevent unwanted polymerization.
- Keep in a cool, dry, well-ventilated place, away from direct sunlight, heat sources, and incompatible materials such as strong oxidizers.
- Use proper PPE including chemical-resistant gloves, goggles, and protective clothing when handling.
- Ensure good ventilation or use appropriate respiratory protection to avoid inhalation of vapors.
