On 19 March 2013 at the European Coatings Congress Croda presents:

Bio-based polyols for high performance polyurethane adhesives

Polyurethanes have been used for many years to produce high-performance materials. Croda has extended its range of hydrolytically stable polyester polyols using 100% bio-based technology, to meet the industry need towards sustainable materials. The new amorphous and semi-crystalline polyols are suitable for reactive adhesives and polyurethane dispersions, where the semi-crystalline material provides improved hardness. It allows adhesives with over 65% renewable carbon content, which is especially a large improvement for dispersions.

These polyols are based on C36 dimer acid from natural oils with a branched non-crystalline structure, which offers (low temperature) flexibility to the bond, prevents strain-induced crystallization and enhances wetting. The hydrocarbon character imparts water repellency and affinity for a wide range of substrates. Furthermore, a unique combination of enhanced hydrolytic and thermo-oxidative stability results, which is highly relevant for demanding applications like sealants, sportswear and automotive adhesives. These properties are demonstrated for reactive adhesives and polyurethane dispersions.

Time: 11:00 - 11:30 hrs
Presenter: Dr. Angela Smits, Applications specialist

On 18 March 2013 at the European Coatings Congress Croda presented:

Novel amine functional dispersant for use with high performance pigments in solvent borne formulations

Recently there has been a trend to use high performance pigments in solvent borne formulations. The complex pigments have properties that make them difficult to disperse, which limits their full performance potential. A novel dispersant technology with amine functionality has been developed for use with these special pigments to provide richer, deeper and truer colors. In addition, reductions were seen in the overall viscosity measurements of the dispersion when both high speed mixing and horizontal milling techniques were employed. Solvent borne formulations using high performance carbon black, rubine red and magenta pigments showed better color development, longer stability and lower viscosities while potentially lowering the addition rates of the novel dispersant.

Time: 13:00 - 13:30 hrs
Presenter: William McNamee, Applications specialist
