Oxazolidine
curing agents
Industrial Copolymers Ltd in the UK has introduced two oxazolidine curing agents which are said to be suitable for use in polyurethane coatings, sealants and elastomers. They are marketed as the Incozol range. Both products are said to enable rapid curing of aliphatic-based moisture-triggered systems without carbon dioxide gassing and subsequent ‘pin-holing’ of the cured material. Also referred to as ‘latent hardeners’, they remain inactive until application, whereupon they hydrolyze to reveal active amine and hydroxyl functions. Incozol 4 is a urethane biz-oxazolidine for general use, while Incozol LV exhibits a considerably lower viscosity than conventional products of this type.

Rheology
modifier
Paraloid EXL 3611 is a methyl methacrylatebutadiene-st,yrene copolymer that facilitates extrusion blow-moulding of nylons by improving melt viscosity at low-shear. Its effect in high-shear regimes is only marginal. The additive is also intended for use in low O1994 Elsevier Science Ltd
molecular weight grades and recyclate, where the supplier says it will significantly improve processing during injection moulding and extrusion. It also improves elongation at break and impact strength, owing to its very low glass transition temperature of -76°C. Contact: Rohm & Haas GmbH, Postfach 940322, D-60461, Frankfurt, Germany.
