The structure of DMPA® Polyol HA-0135 has been specifically designed to achieve maximum hydrolytic stability in water-borne applications. 6X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). Desmodur /Desmophen Basic chemical reactions Film formation in classic two-pack coatings is largely the result of addition reactions between the isocyanate groups of the polyisocyanate and the hydroxyl groups of the polyol compound to form substituted polyurethanes. This may due to the fact that the aliphatic HMDI is flexible and symmetric open chain structure with two primary isocyanate groups whereas the cyclo aliphatic IPDI possess unsymmetric structure in. The ring structure is known as the isocyanurate bond and is not thermally reversible unlike the allophanate or biuret structures. In the case of H 12 MDI, the reaction was performed in a thermostat. COMPARATIVE PROPERTY DATA KD-3013 & KD-4014 Bisphenol-A. sheet3 sheet2 sheet1 these tariff rulings are based on material facts presented and do not absolve the importer from any liabilities that may arise at the time of importation, customs verification and clearance of goods. If stored at higher temperatures, or if moisture is not excluded, an undesirable increase in viscosity will occur. 8 Alternatives to MDI in Consumer Products MOST RELEVANT ALTERNATIVES TO MDI IN CONSUMER PRODUCTS Trade name Product chemistry Application(s) CAS no MDI-based prepolymers Desmodur® E 23 Polyisocyanate prepolymer based on MDI Adhesive (wood bonding, bind-er for corrosion protection), flexible packaging, metal coat- ing. 0 1070 Desmodur VP. to form a NCO. 2 Limit defining parameters The detection limit of the analytical procedure is 0. The pigment was R900 TiO 2 at a pigment/binder ratio of 1. Sustainable coatings from bio-based, enzymatically synthesized Scheme 1 Conventional cross-linkers: I = trimer of hexamethylene diisocyanate (trade name Desmodur N3600), approximate structure; II = isophorone. General notes on this substance group can be found in the corresponding section in Method No. The 4,4' isomer is most widely used, and is also known as 4,4'-diphenylmethane diisocyanate. depend primarily on the extent to which the reactivity of the NCO groups can be influenced by the molecular structure. • The mixture is agitated in a dispenser at 500 rpm.
