Sep 15, 2016The production, processing, and application of aliphatic isocyanate (NCO)based thermosets such as polyurethane coatings and adhesives are generally limited by the surprisingly high viscosity of trifunctionality and higherfunctionality isocyanurates. These compounds are essential crosslinking additives for network formation.(plate) Are isocyanates and thioisocyanates incompatible?Are isocyanates and thioisocyanates incompatible?Isocyanates and thioisocyanates, such as TRIALLYL ISOCYANURATE, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.Triallyl isocyanurate C12H15N3O3 - PubChem(plate) What are the different types of polyisocyanates?What are the different types of polyisocyanates?These raw materials come in two main forms Monomeric Diisocyanates HDI, IPDI and HMDI (and several others) Blocked Polyisocyanates (mainly based on HDI) Blocked Polyisocyanates are supplied as 100% solids and/or dissolved in a variety of solvents.
