Waterborne Polyurethanes for Coating Applications - Bok av Pathik Shah & Sanket Jani - Häftad

Waterborne Polyurethanes for Coating Applications - Bok av Pathik Shah & Sanket Jani - Häftad

Several waterborne polyurethane dispersions were synthesized by using different polyols such as polyethylene glycols, alkyd resin and castor oil, the aliphatic and aromatic di-isocynates, dimethylol proponic acid as ionic center and dibutyl tin dilurate as catalyst. By varying the mole ratios of polyols, di-isocynates and dimethylol proponic acid different waterborne polyurethane dispersions were synthesized. The synthesized Polyurethane dispersions were characterized by IR spectroscopy, particle..

Development of coated electrode introducing nano particles for ADI - Bok av Tapan Sarkar - Häftad

Development of coated electrode introducing nano particles for ADI - Bok av Tapan Sarkar - Häftad

The objective of this book is to develop coated electrode which will be compatible with welding DI and weld metal so produced will respond isothermal heat treatment. Welded joint being a composite material response of different zones (weld metal, partial melting zone, heat affected zone and base metal) of DI weldment towards isothermal heat treatment is utmost important for weld joint integrity and therefore has been studied. Also addition of nano CeO2 in the coating of the coated electrode has been..

Competitive Strategy Dynamics of Oems in the Ict Industry - Bok av Davide (Politecnico Di Milano Italy) Chiaroni - Häftad

Competitive Strategy Dynamics of Oems in the Ict Industry - Bok av Davide (Politecnico Di Milano Italy) Chiaroni - Häftad

Context dynamics in the ICT industry created a new, more ambiguous competitive arena characterised by continuously shifting boundaries. As a consequence, the original equilibrium characterised by vertically integrated companies (and product architectures), and also the 1990s ¿alternate¿ equilibrium of integration and stratification, has been completely broken. A new model of competition for OEMs has been envisioned, characterised by the ¿horizontal¿ competition of specialised players exploiting..
