It can be a good way of both restoring a damaged boat hull at the same time as making it tidy enough to take a mould from. Excellent! And it would bond to Polyethylene?

All you need to do is ensure the pigment you use is an epoxy compatible pigment such as our West & Senior Epoxy Colour Pigment Dispersions.

Group: Forum Members Posts: 4, Visits: 20	Thank you very much Hanaldo and Matt I have already been looking at the XCR resin,I also have a wooden tug hull that is going to need a couple of coats of resin and fine cloth before paint so this product would be useful for that. Final question,is there any reason I cannot add a pigment to the XCR resin as this is clear and being coloured would enable me to see imperfections better and also indicate if I have sanded through to the ABS? Kind Regards Nigel

You'll find that because epoxy is so much harder than polyester that it will take longer to flat and polish compared with the Pattern Coat Primer however, unlike many other epoxies, the XCR resin will polish up to a high gloss, given time. The extra-time polishing the XCR will probably be compensated for by the time and money saved by not needing to use two resin systems to coat it, as you would if you wanted to use the Pattern Coat Primer. Once you have your nice finish on the pattern, epoxy makes a good surface to release from (subject to appropriate release preparation, such as mould release wax or chemical release agent.

There's not a lot of epoxies that polish up too well after sanding, but the XCR resin seems to buff back to a gloss quite nicely from what I have seen. It will be tougher to sand than the pattern coat so it will take a bit of effort, but it looks like it has nice self-leveling properties so you may find it doesn't actually need a whole lot of sanding anyway. Other than that, there's no reason you couldn't pull your mould from an epoxy coated pattern, it will work very well.

Group: Forum Members Posts: 4, Visits: 20	Thank you Hanaldo This does tie in with what I have read regarding polyester resins and ABS on model boat forums.I am now wondering if I can get away with making the Epoxy the final finish to the pattern to save on yet more sanding sessions? Kind Regards Nigel
