UNSATURATED POLYESTER RESINS
The cure of unsaturated polyesters is achieved by the use of a metallic accelerator, typically cobalt, and a peroxide or hydroperoxide initiator to effect the oxidative cross linking of the unsaturation in the polyester resin. DURA offers a number of accelearators and additives which can be used to achieve the desired cure profile.
UNSATURATED POLYESTER RESINS |
||
| Product Type | Product Name | Description / Application |
| Conventional Cobalt Accelerators | ||
| Duroct® Cobalt 6%, 8%, 10%, 12% | Primary accelerators used to promote the crosslinking of unsaturated polyester resins. Color sensitive applications can dictate which cobalt promoter is optimum. | |
| Duroct® Cobalt 12% NDA | ||
| Duranap® Cobalt 6% | ||
| Specialty Accelerators | ||
| Duroct® Cobalt ACD-12 | Specialty accelerator designed to be more cost effective but with excellent activity, lower color and reduced gel time drift | |
| Duroct® Cobalt LC 1080 | Specialty accelerators for FRP and Laminates where cured resin has low final color | |
| Duroct® Cobalt SR 540 | ||
| DriCAT® 10 | Custom blended accelerators for improved performance | |
| DriCAT® 3 | Vanadium accelerator for cold temperature cure applications | |
| Additives | ||
| Duroct® Potassium 15% | Synergistic accelerators used together with cobalt to maintain cure | |
| Duroct® Potassium 15% WW | Water-white Potassium providing improved color | |
| Duroct® Cobalt 21 | Additive used to minimize gel time drift in pre-promoted resin systems, particularly upon storage | |
| Duroct® Cobalt 21R | ||
| Duranap® Copper 8% | Exotherm modifier without negative impact on the cure profile | |
