Description

Dinonyl Maleate is a high-purity diester derived from maleic acid and nonyl alcohol. This compound serves as a versatile intermediate and functional additive, valued for its plasticizing and hydrophobic properties. It is primarily utilized by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to modify material flexibility and performance.

Application

• As a plasticizer and co-monomer in the production of specialty polymers and resins.
• As a lubricant additive and viscosity modifier in synthetic oils and greases.
• As an intermediate in the synthesis of surfactants and corrosion inhibitors.
• As a hydrophobic agent in coatings, adhesives, and sealants to improve water resistance.
• In the formulation of specialty esters for use in metalworking fluids and industrial fluids.
• As a chemical building block for research and development in organic synthesis.
