Affinity™ Light Body XL (Xtra Light) Hydroactive Impression Material

Affinity™ Light Body XL (Xtra Light) Hydroactive Impression Material

Affinity Light Body XL is our most fluid viscosity impression material. Light Body XL is designed specifically to penetrate a 0.2mm impression space and is recommended for healthy soft tissue when it’s difficult to capture impression margins.


  • Light Body XL (Xtra Light) is designed to flow into a 0.2mm sulcus space
  • Ideal for patients with very healthy tissue that often retracts quickly when retraction cord is removed, making it difficult to achieve an accurate impression
  • Combines a unique branched resin, more refined filler and even distribution of surfactant for enhanced accuracy
  • High tear strength
  • Available in Regular Set only

Clinical Technique

Designed to flow into virtually any sulcus, Light Body XL has the highest flow on the market with exceptionally high tear strength.

What are the working and set times of both Affinity regular set viscosities and fast set?2019-05-07T15:45:35-04:00

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.

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.

The combination of Quad-Tray Xtreme with Affinity InFlex and Light Body XL impression material provides me with a “one-two punch” to achieve “knock-out” single tooth impressions. This combination is so fast and easy. I prefer it to my intraoral scanner.
