Ahead of the field (Part 2)

Aliphatic polyester polyols have been produced from seed oil by a novel process that leads to higher performance waterborne polyurethane dispersions (PUDs). In this second part, results of tests which are used in specific wood coating market sectors are reported, showing that good resistance to solvents, staining, scratch, mar and scuffing can be obtained....

Killing the bounce

Sprayed concrete is used in large quantities on major construction projects. As rebound during spraying results in loss of material and affects proper-ties, polymer additives were designed specifically to reduce this problem. Large-scale tests confirmed that adhesion to wet substrates, permeability and cracking could all be improved. The added costs can be more than offset by reductions in working time....

High temperature protection

A range of sol-gel anticorrosive coatings has been developed using active pigments consisting of metal particles coated with a very thin layer of semiconducting titanium dioxide. By appropriate pigment selection, protection can be provided at service temperatures up to 600 °C and for short-term exposure in metal processing operations at up to 1300 °C....
