The unique rheology of RenPaste 4666 enables it to utilise latest automated application technology for rapid production of large plugs and models but still offers the flexibility of manual application as well

Huntsman Advanced Materials is one of the leading developers and suppliers of Seamless Modelling Pastes (SMP) to the worlds manufacturing industries, especially for aerospace, automotive and marine applications.

Having recently introduced the first High Temperature SMP, Huntsman has now developed RenPaste 4666, an SMP designed specifically to utilise the most modern automated rapid manufacturing systems, while still being suitable for refined hand application as well.

This has been achieved through a unique chemical thixotropy developed by Huntsman that enables the user to alter the SMP rheology by simply changing the mixing parameters.

This Programmable Paste Rheology or “PPR” changes the SMPs characteristics from a fluid paste that can be applied down to 10mm thickness, to a viscous material for application up to 40mm, with no slump or excessive exotherm. Because the thixotropy develops only in the mixing head, the unmixed components offer a low viscosity for fast, easy pumping.

The user can select the paste rheology required for individual jobs – from high speed automated application to thick hand application. Different component and mixed paste colours allow rapid assessment of the mix quality.

Whichever application method is used the high quality results reduce the need for additional repairs or re-working of the model, whilst the fine surface quality reduces any further finishing time. RenPaste 4666 exhibits outstanding dimensional stability and low shrinkage which guarantee precision for plugs and models.

As well as its unique variable viscosity, RenPaste 4666 offers excellent adhesion directly to expanded polystyrene, so no costly pre-treatment is necessary. It cures rapidly at room temperatures and is heat resistance up to 80oC after a suitable post cure.

“RenPaste 4666 is a seamless modelling paste which combines unique and patented technology to offer the perfect solution for modern automated production,” said Duncan Howland of Huntsman Advanced Materials. “We believe a range of high performance features will ensure that this paste delivers every time, on time, dramatically reducing the need for expensive repair and finishing work. The rapid pumping rates, fast cure and ease of milling provide the customers with a new standard in rapid production of precision plugs and models.”
