BJB Polyurethane F-181 A/B

About
BJB’s “F-1 Series”, with its 3 to 10 minutes of work time, addresses the need for shorter processing times and higher part production. These 5-95 Shore A products exhibit excellent physical properties and easily process at room temperature. You’ll also find the easy mix ratio to be extremely convenient. F-181 can be cartridge-dispensed with our CPE handheld dispense equipment. For longer work times consider our M Series or L Series of elastomers.
