AFCONA-7530 is recommended to use in unsaturated polyester, PVC, epoxy, and flexible PU compounding applications. It contains hydroxyl, carboxylic, amine and amide groups. These functional groups allow AFCONA-7530 to easily form a hydrogen bonding network that leads to better rheology control.
It very suitable to increase and improve the rheological behavior when used in combination with fumed silica and bentonite clays. This performance leads to better anti-settling which is very important in highly filled systems. Especially in vinyl ester systems, it gives a highly thixotropic paste when combine with fumed silica. We recommend to use a suitable dispersing agent to disperse the fillers/extenders, such as our AFCONA-7500 or AFCONA-7520, for viscosity reduction that enable the desired higher PVC. A high PVC always cause hard settling, thus a combination of AFCONA-7530 and fumed silica will solve the settling problem. The obvious different between AFCONA-7530 and other conventional wetting and dispersing agents are:
- Better in preventing flooding and floating of pigments and extenders due to high hydrogen bond linkage formation
- Works together with the rheology agent to give better anti-settling performance
Note: AFCONA-7530 may become slightly hazy at temperatures below 5° C. This will not impact the performance or quality of the product.
Applications & Uses
- Compatible Polymers & Resins
- Compatible Reinforcements
- Addition and Dosage
- Fumed silica : 10 - 50%
- Other inorganic pigments/extenders : 0.5 - 5.0%
- Incorporation
AFCONA-7530 should be added to the resin mixed homogenously. After incorporation, high sheer force is needed to fully develop the rheology behavior.
