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

If you prefer a light body that is more thixotropic and stays where it’s placed; this is how Affinity Light Body RF (Regular Flow) was designed. Light Body RF lends itself well to those who like to drive the impression material into the sulcus with an air syringe.

Affinity Light Body HF is part of the Affinity line of impression materials that combine a unique branched resin, more refined filler and even distribution of surfactant for enhanced accuracy.

Affinity impression materials feature:

  • Enhanced hydrophilicity for excellent performance in the presence of moisture, especially with subgingival preparations
  • Matched fluid states between the tray and wash materials better capture the preparation site
  • 100% cure to a dense supportive state, which translates to higher tear strength and dimensional stability
  • The blend between Affinity Light Body and Affinity Heavy Body or InFlex is perfect every time
  • Affinity Light Body HF available in regular set for multiple impressions and fast set for single preparations

  1. With tissue management and hemostasis achieved using 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.

  3. After InFlex is loaded sufficiently 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.

  4. 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.

Q: What are the working and set times of both Affinity regular set viscosities and fast set?

A: The working time of Affinity Regular Set material is 1:45 mins with a setting time of 2:30 mins.

Affinity Fast Set materials have a working time of 1:10 mins and a set time of 1:45 mins.

Q: How is Affinity different from other impression materials?

A: 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.

Q: 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?

A: 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.

Q: How can I prevent air bubbles in my wash material?

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

Q: Affinity sets more quickly compared to what I was using before. What can I do?

A: 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.
