RenPaste XD 4618-1 A/B is a cost effective epoxy paste ideally suited for use with the largest CNC milling machines to provide faster and more accurate marine models.
The Marine Engineering Conference (MEC) held in February in Milan, Italy is a key forum for European marine industry innovation.
At this year's conference, delegates received a presentation on the increasingly important role rapid modelling technology is taking in what has been a very traditional manufacturing sector.
Dr Michelle Miller of Huntsman Advanced Materials, explained how epoxy seamless modelling pastes can deliver significant reductions in production time, better dimensional accuracy and stability even on highly complex designs, so cutting overall production and labour costs in the manufacture of marine models and short-run production moulds.
RenPaste Seamless Modelling Pastes (SMP) from Huntsman Advanced Materials have been successfully used in the automotive, aerospace and wind energy industries for more than a decade.
More recently they have also been used in the marine industry, on projects ranging from rowing boats, leisure, speed and racing boats to luxury yachts.
From working closely with their marine industry customers, Huntsman Advanced Materials last year introduced a new version of RenPaste SMP, specifically for marine applications - RenPaste XD 4618-1.
Dr Miller described to MEC delegates how the versatile properties of this new material have enabled marine model-makers and ship-builders to build almost any marine model including full scale hulls and decks, sometimes in excess of 35m in length on highly specialist applications such as bespoke yachts.
RenPaste XD 4618-1 A/B is a cost effective epoxy paste ideally suited for use with the largest CNC milling machines to provide faster and more accurate marine models.
Specially formulated for fast extrusion - with CNC application a future option - XD 4618-1 has high resistance to slump on vertical surfaces.
Once cured, usually after 48 hours at room temperature, the paste exhibits minimal shrinkage, is hard but still exceptionally easy to mill producing a good high quality surface finish that requires minimal hand polishing.
"We wanted to demonstrate to the international marine industry how the benefits of using rapid prototyping technology, already tried and tested in other manufacturing industries, can deliver significant time, cost and design benefits to them as well", said Dr Miller.
"MEC was an excellent forum in which to do this and the feedback we have had from delegates has been extremely positive".
