New barrier gel improves surface
aesthetics
New technology barriercoat Crystic Crestacoat 5000PA introduced by Scott Bader Co, to significantly improve gelcoat surface aesthetics for FRP mouldings.
The new technology barriercoat Crystic Crestacoat 5000PA has been introduced by Scott Bader Co , to significantly improve gelcoat surface aesthetics for FRP mouldings It is designed to create a glossy, high-lustre, ultra-smooth finish which is claimed to significantly outperform even spray-painted finishes as achieved in the automotive industry

Long-term surface protection for moulds
New peelable, tough, temporary protective coating called Crystic Mouldguard has been introduced by Scott Bader Co .
When used with a 'matched-system' skincoat Crystic VE679PA, the new barriercoat gives the best possible surface finish which, in a rigorous 12 month test, also provided the added advantage of outstanding osmotic blistering resistance.
This matched-system can be recommended with confidence for marine applications, or moulded parts used in other demanding environments which are surface-finish critical.
This can include laminate products produced for land transport, building and industrial applications or wherever superior gelcoat surface finishes are specified.

Range of high performance resin systems available from Scott Bader Co has been extended with their latest Crystic Crestapol range.
Crystic Crestacoat 5000PA can also be applied behind the gelcoat in mould making, substantially improving mould surface finish and subsequent moulding quality.
A 1mm thick layer of the barrier coat can dramatically reduce fibre pattern and orange peel effects which can otherwise mar gelcoat finishes.
These common defects can be particularly obvious with darker colours, complex shapes and infused parts.
Following extensive research and development, a unique formulation based upon innovative urethane acrylate technology was used by Scott Bader in the creation of Crystic Crestacoat 5000PA.
It has been proved to technically outperform other vinylester and polyester barriercoats in the creation of superior surface finishes when subject to standard auto-industry DoI measurement tests.
The tough, strong but flexible urethane acrylate resin backbone of this product ensures excellent interlaminar adhesive properties, making it particularly suited for the production of high quality complex parts with sharp corners.
The flexibility also reduces air voids, cracking and pre-release in moulded parts which feature a sharp radius in the design.
The lightweight formulation also means that only 600gm/m2 needs to be put down, using simple spray or brush techniques, to achieve the recommended 1mm overall thickness.
Low exotherm qualities also mean that even large structures can be treated in this manner with confidence.
Long-term surface quality and durability has also been established with products fully submerged for 12 months in water at 40degC without any detrimental effects.
