Methylene Diphenyl Diisocyanate (MDI) CAS:101-68-8 Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock. There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MI contains monomeric MDI and products with higher […]

Teraspartic 230 is an aminofunctional resin with the chemical name: Aspartic Acid, N,N’-(2-Methyl-l,5-Pentanediyl)Bis-,l,l’,4,4′-Tetraethyl Ester, the product is a colourless to pale yellow liquid.
Teraspartic 230 react with a polyisocyanate to make a high solid resin, two-component polyurethane topcoats and solvent-free coating materials.
Production: Teraspartic® 230 is manufactured by the reaction of diethyl maleate with 2 – methylpentamethylenediamine.
Uses: Teraspartic® 230 is designed for use in high-performance, fast-cure, solvent free, low VOC, low-odour coatings for application when properly formulated over a variety of substrates. Applications for polyaspartic coatings include use on concrete, metal, and wood, with and without primer, when properly formulated. Excellent intercoat adhesion also allows application on epoxy and polyurethane. An outstanding attribute of polyaspartic coatings is in one-coat applications that are labour-efficient for the applicator.
Arpadis is the European distributor of the Teraspartic® technology.
