- Mixing and Cure Schedule
To obtain the best cured properties, accurate proportioning and thorough mixing are essential. The production of the desired polyurethane requires accurate measurement of the two components and adequate mixing.
Ratio Part A Part B By weight 100 125 By volume 100 100 The cure schedule is dependent upon the temperature. The recommended cure schedule will vary with the desired properties. The recommended schedule to achieve the typical properties is shown below: 18 hours at 25°C (77°F) -or- 2 hours at 80°C (176°F).

- Storage and Shelf Life
These materials should be stored in a dry environment within a temperature range of 16°C to 27°C (60°F to 80°F). Extremes of temperature beyond this range may result in crystallization or polymerization of the materials. Introduction of a nitrogen blanket into the containers before closing will improve the storage life of the products.
