Abstract

PURPOSE: The captioned composition which comprises making combination use of organic carboxylic acid and organic sulfonic acid as acid hardeners, permits adjustment of pot life over a wide range, hardly hardens at about 40°C or less and is capable of forming molds of high strength.
CONSTITUTION: Organic carboxylic acid (a) such as malonic acid, succinic acid or benzoic acid, organic sulfonic acid (b) such as paratoluene sulfonic acid or benzen sulfonic acid, organic self-curing resin (c) such as furfuryl alcohol formaldehyde resin or phenol formaldehyde resin and silica sand (d) are compounded to prepare the composition for organic self-hardening mold. Here, the amount of using the abovementioned carboxylic acid is made about 2W90wt% of the total acid hardener (preferably 10W50wt%).
