Whip Mix LeanRock XL5 ISO Type 4 Dental Stone Ivory 33 lb / 15 kg

Whip Mix LeanRock XL5 is an ISO Type 4 dental stone formulated for laboratory use, designed to support small-batch processing of approximately six models at a time. Models are ready to trim and pin in just 15 minutes, with a working time of 4–5 minutes and a setting time of 5–7 minutes at a water-to-powder ratio of 20 mL/100 g. This rapid turnaround reduces workflow bottlenecks by allowing smaller batches to move down the line continuously rather than in large groups. The stone delivers a wet compressive strength of 3,500 psi at 15 minutes, rising to 7,200 psi at one hour and 11,900 psi (82 MPa) when dry at 48 hours, with a setting expansion of 0.20%. Available in ivory, this 33 lb / 15 kg package is well suited for remakes and time-sensitive repairs.
