Affinis is an A-type silicone with a surface affinity and ideal viscosity properties: - Its rapid and unique affinity with the moist structure allows it to flow like a hydrocolloid, reaching the most critical areas without the need to exert any pressure with the tray material. - The special combination of additives creates minimal resistance to viscosity (self-adapting consistency), preventing air entrapment while the material is sufficiently thixotropic to avoid dripping outside the preparation.
