Information on new resin products comes to our Editor on a regular basis and is normally featured in the "Materials" section of our regular features.

Most of them, as perceptive readers will know, are variants of existing products from specific manufacturers. One that caught our eye, and which we thought warranted "upgrading" to this Comment page, is a new pure acrylic emulsion with what is said to be a unique self-crosslinking feature. Known as NeoCryl XK-98, it is produced by NeoResins (formerly Zeneca Resins) of Waalwijk, The Netherlands.

The self-crosslinking feature was designed for fast drying and fast blocking resistant coatings for exterior wood and industrial joinery products. It is claimed to be suitable for transparent as well as for opaque systems with excellent elasticity, good blocking and early water resistance even at high coating thickness. The thickener response of NeoCryl XK-98 is such that non-sagging can be obtained even at a wet coating of 400-500µm.

It is further claimed that being an ultra fine particle size emulsion, the product shows an almost solvent based like "in-can clarity", which is an attractive feature for clear lacquers in DIY applications. The product is also reported to show no yellowing and good adhesion on different substrates like PVC-plastic, ferrous and non-ferrous metals, pre-painted and solvent-based wood primers, making it very suitable as a universal primer paint.
