PRODUCT OVERVIEW

Product Description

ATMP (Amino Trimethylene Phosphonic Acid) is an organophosphonic material supplied in both aqueous and high-purity crystalline grades for selected industrial applications. The referenced 50% grade is supplied as a clear, colorless to pale-yellow aqueous solution, while the 95% grade is supplied as a white crystalline powder. ATMP is characterized by metal-ion complexation and scale-control properties that support its use in selected industrial water-treatment and processing formulations. It may also be considered for compatible textile, dye-processing, and metal-treatment applications. Product suitability, grade selection, handling requirements, and technical performance should be confirmed against the current supplier SDS, COA, and applicable regulatory documentation.
