FRACSAL WATERBASE® EM1

1 of 8 products in this brand
FRACSAL WATERBASE® EM1 is consists of a specially sized, sparingly-soluble borate crosslinking agent suspended in an aqueous solution. Fracsal Waterbase EM series contains a solubilized alkaline salt modifier which is capable of adjusting the rate at which gelation of organic polymer occurs, without substantially altering the final pH or other characteristics of the crosslinked system. Typical usage concentrations for all Fracsal Waterbase EM products is from 1 to 3 gal per 1,000 gal of fracturing fluid with crosslink times ranging from 1 minute to 3.5 minutes depending upon the pH, temperature, and type of polymer-based fracturing fluid system.

Functions: Crosslinking Agent
