Crystic® Gelcoat 14PAHigh Performance Tooling Gelcoat
Crystic Gelcoat 14PA is a pre-accelerated brush gelcoat, designed for use in the manufacture of high quality FRP composite tooling.
˜ Signi�cantly increases the lifetime of moulds in production˜ Enhanced gloss �nish and gloss retention compared to competitive products˜ Eliminates water-marking˜ Reduced �bre print-through resulting in a much smoother gelcoat surface˜ Easy to apply to required thickness˜ Fast mould production˜ Easy to de-mould even complicated shapes
A Genuine Solution to the Problem of Water-MarkingWith its unique combination of properties, Crystic Gelcoat 14PA has shown that it can overcome one of the most serious problems associated with FRP composite tooling - the phenomenon known as water-marking. The imperfections associated with water-marking can only be seen on the mouldings taken from the mould. Attempts at water marking repairs on moulds have limited short-term success.
When using Crystic Gelcoat 14PA you can expect elimination of water-marking imperfections and the mould to have:-
Technical Bene�ts
˜ a uniform level of gloss across the whole surface˜ a smooth �nish with no surface undulations
“Hi Spec Plastics have been in business since 1968 designing and manufactuing life raft containers and parts for Marine, Aviation and leisure industries. Over the years we have tried and tested a number of di�erent tooling gelcoats but none have exhibited the performance excellence of Crystic 14PA. One of the moulds produced using 14PA has had over 4,000 lifts over a number of years with no evidence of dulling, crazing or cracking of the gelcoat surface. Crystic 14PA has exceeded all our expectations for a tooling gelcoat and we strongly suggest you try it.”
Gary Bates - Managing Director, Hi Spec Plastics

RTR 4000PA is a pre-accelerated low profile, thixotropic resinspecifically designed for rapid tool making. It has improved shrinkage control giving good handling and rapid cure. It is catalysed with MEKP.
474PA is a thixotropic, pre-accelerated polyester resin with goodheat and chemical resistance properties. It is ideally suitable forthe production of heat resistant, dimensionally stable moulds.
Apply Crystic Glosscoat toplug and polish2
Glosscoat is used alongside Primecoat to give a glossy,highly durable surface finish
It is also important to ensure the plug is of a high standard, as this will affect the quality of the mould.

"As Technical / R&D Director of Wessex Doors / Wessex Composites I am happy to recommend this product to other manufacturers of composite components and tools without hesitation."
Wessex initially changed to 14PA gelcoat after trying several iso tooling gelcoats in our standard build method for RTML tools. With the iso gelcoats we found that the moulds suffered stress cracks and excessive shrinkage from post curing at 85oc, and from continued cycling in production at 55 to 75oc.
Wessex has compared 14PA to several other leading brand gelcoats of similar composition and properties within its R&D department. It was found that the 14PA did not suffer micro cracking from post curing, its application was easy and fluid, and the longevity in production was far better than expected; even in high styrene attack situations.
We have now made numerous large RTML tools for a superyacht client using this product and currently have a further 13 in production all manufactured using 14PA. Wessex also plans to manufacture all future tools for pre-preg epoxy use with 14PA. The product is also very competitively priced. out of the 50+ multi part RTMl tools we have manufactured these are the most robust.
Recently Wessex has also used this gelcoat to manufacture the base of a 6.5m x 3.6m vacuum press for heavy production use; we chose this product due to its inherent stability, and gloss retention. Wessex now use this gelcoat as the basis for all our plugs, tools and moulds whether they are RTML, hand lay, resin infused or for pre-preg use. All our production tools are post cured at a minimum of 80oc and the Scott Bader 14PA product has shown no problems whatsoever.
As Technical / R&D Director of Wessex Doors / Wessex Composites I am happy to recommend this product to other manufacturers of composite components and tools without hesitation. Scott Bader offer excellent products and service, and Wessex looks forward to furthering our business with them.
