ETERNACOLL® polycarbonate diols are used mainly in the manufacture of high-performance polyurethane coatings, adhesives & sealants, and elastomers. The origin of these higher performance in polycarbonate diol based polyurethanes, compared to their traditional counterparts as polyester diol or polyether diol, is due to the presence of carbonate group in the polymer. This group is much more stable against hydrolysis than the ester group and also has a greater stability against UV radiation and high temperatures than the ether group.
Polyurethanes based on ETERNACOLL® polycarbonate diol present the advantage compared to those prepared with traditional polyurethanes, a very high durability against degradation agents such as hydrolysis, chemicals, thermal degradation effect or UV.
ETERNACOLL® polycarbonate diols can directly replace your current polyols in formulations in waterbased, solventborne and 100% solids polyurethanes, just requiring minor modifications to adjust the formulation to the new polyol.
ETERNACOLL® polycarbonate diol can be reacted with any kind of isocyanate, as any other standard polyol. Furthermore, polycarbonate diol can be used as single polyol, as well as blended with other standard polyol, showing full miscibility with the most standard ones.
