Affinity™ Light Body HF Hydroactive Impression Material

Our most popular light body impression material, Affinity Light Body HF (High Flow) flows on its own under the hydraulic pressure of the tray material and flows effortlessly into the sulcus.

Performing beautifully in the presence of moisture, the blend between Light Body HF and Affinity Heavy Body or InFlex is perfect every time.

How is Affinity different from other impression materials?2019-05-07T15:46:24-04:00

Only Affinity uses branched resin chemistry for 3-dimensional cross-linking resulting in a higher tear strength, refined fillers, and an even distribution of surfactant. Other impression materials use linear resin chemistry with an uneven distribution of surfactant resulting in less accurate impressions that are more prone to tearing of the thin interproximal and sulcus fins.

I really like my light body from another brand. Can I use Affinity Heavy Body (or other Affinity Tray Materials) and my light body together?2019-05-07T15:47:55-04:00

Light and heavy body materials from another brand may be mixed but strict attention must be paid to the working and set times as they need to mimic or exceed Affinity’s.

How can I prevent air bubbles in my wash material?2019-05-07T15:48:11-04:00

Always keep the tip of the mixing tip fully immersed in the Light Body fully as it is syringed around the prep sites.

I’m having difficulty loading Affinity InFlex into Quad-Trays. Are there any tips that will help?2019-05-07T15:48:27-04:00

It is important to work quickly when loading Quad-Trays. Dispense Affinity InFlex in an S-pattern onto the non-prep side after running a bead of material around the periphery of the tray. Immediately turn the Quad-Tray over and repeat on the prep side.

Affinity sets more quickly compared to what I was using before. What can I do?2019-05-07T15:48:40-04:00

If using Fast Set, switch to Affinity Regular Set impression material. Do not attempt to adjust the temperature of the material in order to slow down the set.
