Performance Additives for Paints
Governments and industry round the world are moving toward GREENER ways of producing high performance paints. Government legislation from the likes of SED: Solvent Emission Directive, NEC: National Emission Ceiling and CAFE: Clean Air For Europe are leading this change to reduce environmental emissions from solvent based paints. This includes using less solvents based paints in favour of either low VOC (Volatile Organic Compound) or water based paints. One of the challenges is that solvent based paints clearly outperform water based equivalents. Until now…
Buhler in conjunction with Micronisers Australasia have produced a range of performance additives for water based paints (OxylinkTM) that improves the cross-linking of the resin from within and thus strengthens the film against impact from the outside.
Oxylink™ brings performance improvements in:
- Humidity resistance
- Chemical resistance
- Corrosion resistance
- Drying time
- Blocking resistance
- Dirt pick-up resistance
- Efflorescence resistance
OxylinkTM is a registered trademark of Buhler AG.
Additives for Protection from UV
Exterior paints are designed to provide protection from outdoor weathering, especially the deterioration caused by UV radiation. Australia is no exception with some the harshest conditions on the planet created by our extreme summers producing very high levels of UV radiation. Therefore, a UV shield is critical to ensure adequate protection of any substrate from the harmful rays of the sun.
If long term protection is required, then Microsun Zinc Oxide is the preferred additive as compared to organic UV absorbers which readily breakdown. Ideal for use in clear and stain finishes where transparency is important along with architectural and industrial finishes.
