BC RRM-Fast Set Putty contains the same characteristics as our tried-and-true BC RRM Paste BC-RRM Putty but with a new fast set chemistry and an improved Sanidose syringe delivery. There is no mixing, no waste, and no cross contamination. Best of all, you get a consistently perfect unit dose putty plug with every application. BC RRM-Fast Set Putty takes 20 minutes to set and is even more resistant to washout than our market-leading BC RRM-Putty!
