Hydrophilic Polyester Polyol LDMPA J5804 Widely used in various applications synthetic leather water-based polyurethane water-based resins
LDMPA is a hydroxyl-containing polycaprolactone obtained through the ring-opening of DMPA to form E-caprolactone. It retains the excellent properties of both hydroxyl and neopentyl structures while featuring a low melting point and excellent compatibility with polyester diols. As a polyester-type diol, LDMPA offers superior weather resistance and heat resistance compared to polyether polyols, along with enhanced hydrolysis resistance over adipic acid esters. It improves strength and abrasion res
Dihydroxymethylbutyric acid (DMBA) J5803 paints inks adhesives and leather finishes
DMBA is a neopentyl carboxylic acid bearing two active functional groups, making it suitable for synthesizing water-based polymer systems. It finds extensive applications in water-soluble polyurethanes, polyesters, epoxy resins, water-based resins, paints, coatings, inks, leather finishing, electronics, and adhesives. DMBA exhibits superior solubility compared to DMPA in various solvents, significantly enhancing operational efficiency. It is regarded as a new-generation green chain extender and
Dihydroxymethylpropionic acid (DMPA) J5802 Widely used in the production of coatings
DMPA is a unique multifunctional, sterically hindered diol molecule containing both hydroxyl and hydroxyl groups. It serves as a chain extender and hydrophilic agent, finding extensive application in the production of water-based polyurethane/polyester coating systems, water-based resins, paints, inks, adhesives, and leather finishes.
Chain extender JTA95 J5801 Waterborne polyurethane Combine the performance of emulsifier and chain extender
Chain extender JTA-95 is an aqueous solution of sodium sulfamate. The amino groups at positions 1 and 2 combine the performance of emulsifier and chain extender in the process of synthesizing aqueous polyurethane dispersions. The polyurethane dispersion synthesized with it improves the stability and compatibility with other anionic or nonionic dispersions. Due to the lower ammonia value, the hydrolysis stability of the polyester in the aqueous polyurethane dispersion is improved.
