Affinity™ Light Body HF Hydroactive Impression Material

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.


  • Combines a unique branched resin, more refined filler and even distribution of surfactant for enhanced accuracy and excellent performance in the presence of moisture, especially with subgingival preparations
  • Light Body High Flow is Affinity’s most popular Light Body
  • Light Body High Flow is thixotropic to prevent running and flows beautifully into the sulcus under the hydraulics of the AFFINITY Tray Materials, resulting in outstanding impression accuracy
  • 100% cure, which translates to one of the highest tear strengths in the industry
  • Blends seamlessly with Affinity Heavy Body and Affinity InFlex
  • Available in regular set for multiple impressions and fast set for single preparations

With tissue management and hemostasis achieved (Tissue Goo Hemostatic Gel), the preparation is cleaned with Detail Pre-Impression Cleansing Gel to remove any residual debris and hemostatic agent ensuring complete polymerization of the Affinity InFlex VPS tray material and Affinity Light Body VPS material.
The Affinity Light Body impression material is placed after the Re-Cord #00 cord has been carefully removed, making sure to keep the tip submerged.
After InFlex is loaded suffiently into the Quad-Tray Xtreme, the tray is placed immediately. The patient is asked to passively close. If no segmental bite registration has been taken prior to the impression, the patient may need to be guided into position.
While holding the tray firmly at the base of the handle, gently rock the impression material until it releases. Never torque the handle of the tray to prevent bending of the aluminum body.
The final impression showing excellent capture of the margins as well showing the Light Body was not displaced by the hydraulics of the InFlex. This ensures a more accurate die and better fit of the final restoration.
Due to the accuracy of the impression, the final ceramic restoration fit beautifully with little adjustment required.

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.
