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).
Toluene diisocyanate (TDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HMDI), and diphenyl methylene diamine (DPMD) were used as activators and CLNa was employed as catalyst.
In addition, LANXESS offers IPDI (isophorone diisocyanate) based Trixene prepolymers used in industrial coating applications that require high resistance to weathering and chemicals.
The self-healing properties of coatings were found to be linked to macro-organisation of polymer chains caused by interactions between HS and SS of the polyurethane moiety, leading to phase-mixing, promoted by bulky, non-symmetrical isophorone diisocyanate, or phase-separation, promoted by linear, symmetrical hexamethylene diisocyanate.
Among the three amines tested as chain extenders (isophorone diamine, polyetheramine, CNSL-phenalkamine), the amine characterized by the lowest molecular weight shows the highest effect on deblocking temperature, probably due to its lower steric hindrance and the subsequent easier access to reactive groups (Figure 6).
Evonik has been the reliable partner and solution provider in the field of isophorone chemistry for more than 55 years.
1 to 3 wt% isophorone diisocyanate is added as the coupling agent along with 5 to 40 wt% 1,6-hexamethylene diisocyanate as the impact modifier.
The film-forming polymer comprises polyoxypropylene (17) isophorone diisocyanate and dimethylol propionic acid copolymer (PPG-17/IPDI/DMPA copolymer).
