S-RIM™ is a series of advanced casting resins that exhibit high physical properties and are extremely fast curing.
- Easy to mix with a 1:1 ratio by volume.
- Available in black or natural/tan.
- Available in 25 or 60 sec. gel time.
- Can be de-molded in less than 5 minutes!
S-RIM™ products are truly unique in that they exhibit incredible “green strength”, achieving up to 80 percent of their final physical properties within the first 10 minutes. This makes them ideal for creating prototypes or production parts that must ship under time constraints. With 25 & 60 second gel times, the use of meter-mix dispensing systems is highly recommended, especially for larger castings.
