The range of high performance resin systems available from Scott Bader has been extended with their latest Crystic Crestapol range.
Crestapol 1210 is designed for use in RTM (resin transfer moulding) and pultrusion applications, with a partially pre-accelerated grade (Crestapol 1210A) also being available.
Crestapol 1210 and 1210A are suitable for the production of diverse products such as; railway furniture, domestic household doors and garage doors as well as general buildings and construction products, including modular buildings. Fire resistance or other specific properties can be incorporated with the use of selective fillers, making the resins ideal for mouldings designed to handle demanding use in road, rail, plane or marine transportation applications. These resins are of particular interest where a combination of high application performance with manufacturing productivity is critical to ensure competitiveness.
Scott Bader says that are low viscosity resins, with excellent toughness, which cure rapidly, and that production can be optimised to achieve a cycle time of as little as six to seven minutes for RTM. The resins require the addition of a catalyst plus two accelerators (only one for Crestapol 1210A) to start the curing reaction. The recommended catalyst is Akzo Trigonox® 44B used with Scott Bader Accelerator G, with dimethyl aniline (DMA) required in addition only for use with Crestapol 1210 resin.
Crestapol 1210 and Crestapol 1210A can be supplied in 25kg, 200kg and one tonne containers and should be stored at low temperatures (less than 20° C) where possible. The image shows a demould operation with 6min 30sec cycle time for the production of a moulding using the latest Crestapol 1210 resin.
