Alumilite’s Vac 25 provides users with an extremely durable and abrasion resistant rigid urethane that has good overall physical properties and low shrink. Vac 25 is the best choice when abrasion resistance is required.

The Vac 25 has a mix ratio of 1:1 by weight and needs to be agitated prior to measuring. The material features a 6-8 minute work time with a demold time that ranges from 2-3 hours depending on the mass of the material being cast.

Vac 25 is a great choice for vacuum or thermo-form tooling as well as nests, check fixtures, and applications where high abrasion is required. Vac 25 is not recommended for machining as some of the raw materials that provide high abrasion resistance are very hard on tools and bits which will wear down quickly.
