The call was made on Tuesday at a press conference held by the National President of IPDI
, Comrade Austin Ozobo, with his secretary, Comrade Peter Luke, and the National Coordinator of IIA, Amb.
In order to first determine the behavior of NX-2026 as an NCO blocking agent, model isocyanate-NX-2026 adducts were prepared, using both aliphatic and aromatic isocyanates (MDI, TDI, IPDI
, HDI, pHDI) and resulting adducts were then characterized for their deblocking temperatures.

), dibutyl tindilaurate (DBTDL) (Sigma-Aldrich), hydrogen peroxide (30% w/v), 98% sulfuric acid, sodium sulfate, sodium bicarbonate, hydrochloric acid, sodium chloride, sodium hydroxide, xylene, glacial acetic acid, toluene, acetone (s.d.
In this study, a novel UV-curable cyclohexanone-formaldehyde (UVCF) resin was synthesized with cyclohexanone-formaldehyde (CF) resin, isophorone diisocyanate (IPDI
), and pentaerythritol triacrylate (PETA) as base substance, bridging agent, and functional monomer, respectively.
PEG (MW = 1000.800 Da), IPDI

In the first step urethane monoacrylate was obtained by the reaction of an equimolar amount of IPDI
Complete line of aliphatic and aromatic poly-isocyanate crosslinkers based on HDI, IPDI

The agency also gave an LAA (pronounced L double A) rating with a "stable" outlook to the bank's IPDI
Tier I bonds programme and upper Tier II bonds programme.
