The new method, which uses swabbing material to collect samples of explosives, is able to detect substances such as nitrotoluenes, trinitrotriazine, hexamethylene triperoxide diamine and nitroglycerine.
The LF technology creates prepolymers with < 0.1 wt.% free MDI (methylene diphenyl diisocyanate) and other isocyanates such as TDI (toluene diisocyanate), HDI (hexamethylene diisocyanate) or pPDI (p-phenylene diisocyanate), providing unsurpassed industrial hygiene standards, excellent performance, and improved processing.
The prepolymers are available for all isocyanate and polyol chemicals, including special isocyanates such as IPDI (isophorone diisocyanate), HDI (hexamethylene diisocyanate) and PPDI (p-phenylene diisocyanate).
Prepolymers from the Adiprene LFH range, based on the aliphatic diisocyanate HDI (hexamethylene diisocyanate) are particularly suitable for long-lasting, high-quality outdoor applications due to the excellent color retention and high clarity of the coating.

Summary: Six new N-acetylglycine amides and bisamides were prepared by reacting N-acetylglycine with different isocyanates including, hexamethylene diisocyanate, bis(4 - isocyanatophenyl)methane, toluene 2,4-diisocyanate, 1,3-bis(2-isocyanatopropan-2-yl)benzene, phenyl isocyanate and 2 -naphthyl isocyanate to furnish amides 1-6.
(37) Furthermore, the refractive index of PHMGH (poly (hexamethylene biguanide) hydrochloride -1.5486 (38)) is similar to the index of the co-monomer blend (mixture of BisGMA, TEGDMA, and HEMA - 1.47 to 1.59 (monomer) and 1.50-1.62 (polymer) (18)).
The Wales Extremism and Counter Terrorism Unit and South Wales Police found triacetone triperoxide (TATP) in the fridge of the couple's home in Archer Crescent on August 29, and another explosive substance Hexamethylene Triperoxide Diamine (HMTD) was found in the garden shed.
He cited unplanned production disruptions at key intermediate plants--including precursor ADN (adiponitrile) and derivative HMD (hexamethylene diamine) in France and the U.K., along with other logistical problems such as transportation strikes.
Another substance, hexamethylene triperoxide diamine (HMTD) was allegedly discovered elsewhere in the property.
The court heard that police allegedly found triacetone triperoxide (TATP) in the fridge of Harris' house and that another explosive substance, Hexamethylene Triperoxide Diamine (HMTD), was allegedly discovered in his garden shed.
