A new class of anti-adhesive coatings has been studied for potential use in industrial food production. They can be sprayed and cured at lower temperatures than current PTFE coatings. The polymer binder matrix incorporates perfluorinated comonomers and nanoscale hard particles. Polyurethane-based systems gave the best abrasion and chemical resistance, but a polyimide-based system performed well in dry processing tests....

A new water repellent additive for cement-based materials is supplied in the form of a dry emulsion which is self-dispersing in water. On both grouting and facade materials, the emulsion product gave much better bulk hydrophobisation than standard water repellents. It also reduced colour changes after wet/dry cycling and algal growth....

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....

It can be difficult to formulate coatings which are able to retain easy-clean or stay-clean properties after abrasion or other damage. Three different approaches to creating coatings of this type are described. All make use of the synergy between the oleophobicity of fluoropolymers and the resistance to wear provided by silicone-based materials....

Hydrophilic polyurethane (HPU) membranes are widely used in the construction of various types of ‘breathable’ fabrics. The history, formulation, application procedures and end-uses of these materials are outlined. In addition to many different forms of functional clothing, HPU systems are used in a growing range of medical applications...
