Supplied in a convenient 150g pack, it pairs particularly well with polyester resin systems used alongside chopped strand mat and other fibreglass reinforcements, making it a useful addition to professional composite and repair workshops.

For fibreglass fabricators and repair professionals, Butanox M-50 provides dependable curing and consistent results for quality composite work.
