An isocyanate-terminated prepolymer is prepared as described in Example 4. One hundred parts of this prepolymer is mixed with 20 parts of Composition K to form a diluted one-part, room-temperature latent, curable isocyanate composition. The composition is degassed in a vacuum desiccator and then ...
It can be made per code number or according to the drawings from customers. The normal used material is ductile iron, like GGG 40, GGG 50, produced in sand casting process. We're experienced in making the Turbo housing for more than hundred of types, and for some parts made...
The longevity of the HNC membrane is enhanced from a few hours to a few hundred hours by clamping it between two half-coated Nafion 212 membranes. The degradation mechanisms are discussed based on the physicochemical analysis of the membrane and its degradation products after electrolysis....
this really places the interpretation of Verdejo on a whole other level, with much more complexity than is common with this grape and wine. Made with the best grapes from a roughly one hundred years old vineyard, the wine was named after the winery’s former president, Amador Diez de Ísc...
