Dispex® Ultra PX 4575

Dispex® Ultra PX 4575 is a water-based dispersant made by Controlled Free Radical Polymerization (CFRP). This technology allows the synthesis of polymeric dispersants with highly defined polymer architecture and a low poly-dispersity index. Dispex® Ultra PX 4575 is especially suited for the dispersion of pigments in waterborne coatings and colorants.

2-Ethyl-4-Methylimidazole

2-Ethyl-4-Methylimidazole is a selective catalyst for epoxy and urethane reactions. 2-Ethyl-4-methylimidazole is used for two components epoxy systems, for the modification of epoxy resins and for preparation of polyurethanes.

2-Ethylhexanoic Acid, 2-EHA

2-Ethylhexanoic Acid, 2-EHA is a building block for alkyd resins and for production of organic metal salts. Alkyd resins modified with 2-ethylhexanoic acid are used in stoving enamels and two-component paints (primers and topcoats). Metal salts of 2-ethylhexanoic acid are used for siccatives in oxidative drying paints and printing inks.

2-Ethylhexylvinylether, EHVE

2-Ethylhexylvinylether, EHVE is a monomer for copolymers with vinyl chlorides (Laroflex®) or TFCE 1,1,2-trifluoro-2-chloroethene. Copolymers with 2-Ethylhexyl vinyl ether are used for solvent based anti-corrosion coatings. Vinyl ethers form alternating copolymers via charge transfer-complex polymerization with electron-deficient monomers, such as vinyl chlorides, maleic anhydride, TFCE, resulting in better solubility and flexibility.

2-Ethylimidazole

2-Ethylimidazole is a selective catalyst for epoxy and urethanes reactions. 2-Ethylimidazole is used for two components epoxy systems; for modification of epoxy resins and for preparation of polyurethanes.
