The lady there tells me it's not called rigidizer anymore and shows me this stuff called "hotline mild hardener". the catalog description says "used to harden fiber mild constructions. easy to apply and sand to a smooth finish." fiberboard would not brake down like fiber blanket.. Designed to harden fiber paper mold constructions. apply to the fiber mold with a brush and cure at 175 degrees fahrenheit until surface is hard. mold surface can be sanded to a smooth finish. repeat the process, and the mold will be ready for firing to 1. A syringe of "5-minute" epoxy glue, containing separate compartments for the epoxy resin and the hardener. structure of the highly reactive epoxide group present in all epoxy resins. epoxies are also used in producing fiber-reinforced or composite parts..
