allnex introduces UCECOAT® 7230, its first waterborne UV-curable dispersion aimed at a wide variety of plastic hardcoat applications
DROGENBOS, (December 20, 2017) – allnex, a global leader in energy-curable technology for industrial, graphics, consumer electronics, plastics and special purpose coatings and inks, today announced the launch of its new UCECOAT® 7230 developed for hardcoat applications on plastics.
Our most recent addition to our range of waterborne UV-curable resins, UCECOAT® 7230 is a new and highly versatile unsaturated aliphatic polyurethane dispersion based on a swollen particles concept.
Designed to be used on a wide array of plastic substrates, the main properties of this new product - namely its great adhesion properties, which help circumvent the greatest challenge formulators face when dealing with such substrates, ease of application, good resins compatibility, high flexibility and low yellowing - allow it to be suitable for various hardcoat applications. It will therefore help serve a multitude of segments within the plastic coatings market, including industrial and automotive plastics, plastics sheets and films, consumer electronics, but also flooring.
Being a water-based dispersion (and therefore solvent-free) as well as Tin-free also makes UCECOAT ® 7230 100%-compliant with the latest environmental regulations (REACH…) and VOC (Volatile Organic Compound) emission restrictions, all the while providing formulators with a superior coating performance.
Key benefits and features of UCECOAT® 7230 include:
- Direct adhesion to most plastics
- Good substrate wetting
- High reactivity
- Very good balance of hardness and flexibility to reduce cracking or brittleness of the coating
- Good compatibility with waterborne resins for boosting other performances
- Neutral to slightly alkaline pH
- Excellent humidity, abrasion and hot water resistance
- Excellent optical properties (high gloss and low haze)
- Low yellowing after cure
- Low viscosity
