-- Product Description
3-Mercaptopropionic Acid (MPA) is a clear, colorless to pale yellow liquid with a strong thiol odor. It is a key organic intermediate containing both thiol (-SH) and carboxyl (-COOH) functional groups, making it highly reactive and useful in a variety of chemical applications. MPA is widely used in the production of polymers, coatings, adhesives, and particularly in the synthesis of polycarboxylate superplasticizers (PCE) for the construction industry.
-- Main Applications
Synthesis of polycarboxylate superplasticizers (PCE)
Reactive intermediate for UV-curable resins and coatings
Modifier in adhesives and polymer formulations
Used in chelating agents, dispersants, and metal surface treatment
Intermediate for pharmaceuticals and agrochemicals
-- Product Advantages
Dual-Function Reactivity: Contains both thiol and carboxylic groups for versatile applications
High Purity & Stability: Ensures consistency in polymer synthesis and reactions
Essential for PCE Synthesis: Improves molecular structure and water-reduction performance
Eco-Friendly Potential: Suitable for low-VOC and water-based systems
Excellent Performance Booster: Enhances dispersion, fluidity, and workability in construction additives
