"Alese Jewell is very helpful and I appreciate how quickly she responds to emails, etc."

Chemical Distributor

"We're very happy with the Austin Black we purchase from CFI. It's become the main filler we use in one of our potting sealants. We've found that Austin Black can be used at higher concentrations than standard carbon blacks without significantly increasing the viscosity of the sealant. Customer service has also been great. Cyndi Foley has been our primary CFI contact. She has been excellent to work with, and is very helpful and responsive."
