Cross-linking agent binder component

TDI has a flash pt of 132° (open cup) and flammable vapor level limits of 05 to 9.5% 2,4-Tolylene diisocyanate is used as a constituent (cross-linking agent) of polyurethane expls, proplnt binders, and as a component of a ballistic modifier (Refs 2a, 8 9). Se in Vol 8, P6 8-Table 3 under PBX Type Explosives-Composition (listed as Polyurethane in the Binder, % column), and P409-R to P415-Table 17 under B. Composite Propellants ... 

Embedding microcapsules into textile substrates requires a soUd knowledge of interfacial phenomena at a molecular level as well as the physical characteristics of all the components present in the system. Among the principal parameters to be considered when applying microcapsules to textiles in a durable, efficient, and noninvasive manner are microcapsule shell composition, functionalities of textile fibers, chemistry of binders/cross-linking agents, and fabric architecture. 

Matting agents are used to produce coatings with a matt, semi-matt, or silk finish. They include natural mineral products such as talc or diatomites and synthetic materials such as pyrogenic silicas or polyolefin waxes. Matting can also be obtained by special formulations that exploit the incompatibility between binder components and their cross-linked structures.
