Acrylic Acid
Applications
It serves as a building block for superabsorbent polymers, dispersants, thickeners, and pressure-sensitive adhesives. In coatings and textiles, it contributes to improved film formation and substrate adhesion.
Safety & Risks
Corrosive and prone to spontaneous polymerization under heat or contamination. Maintain inhibitor levels, ensure inert gas blanketing, and avoid contact with oxidizers or bases. Adequate ventilation and PPE are mandatory during handling.
Packaging
Stabilized product supplied in lined steel drums, IBCs, or ISO tanks under nitrogen. Store below 25 °C in dry, ventilated conditions away from light and ignition sources.
