New Scott Bader Crystic Gelcoats – A Generation On

15 April 2003

Scott Bader has developed next generation spray and brush gelcoats with better performance, which were officially launched at the JEC 2003 exhibition. These new products are suitable for both marine and non-marine applications, such as building, land transport and general moulding.

Two new, low styrene marine approved spray gelcoats have also been added to the Crystic isophthalic spray gelcoat range; Crystic Envirotec LS 97PA (filled) and Crystic Envirotec LS 99PA (unfilled). As well as having weathering, blister and osmosis resistance, these new spray gelcoats give moulders the added benefits of low odour, with even lower styrene levels during application. All Crystic Envirotec gelcoats have benefited from recent R&D developments to improve weathering resistance.

The new brush gelcoat is Crystic Envirotec LS88PA. It has Lloyds approval and retains the handling characteristics typical of Scott Bader gelcoats. It is the next generation to the 30 year proven performance of Crystic 65PA and will suit customers looking for a reliable, high quality product with outstanding weathering performance, which also offers ease of application and low styrene emissions.

When compared with Crystic 65PA, Crystic Envirotec LS88PA is a step forward in overall product performance, both above and below the waterline in marine applications. The weathering performance of Crystic Envirotec LS88PA is outstanding and significantly improved over Crystic 65PA. After 12 months exposure in Florida, panels manufactured using Crystic Envirotec LS88PA had retained 100% of their gloss levels, with very limited colour change visible. In addition, the styrene content has been reduced by 15% compared to Crystic 65PA, in response to customer demands to keep emissions in production areas to a minimum.
