This glue is exclusively designed for plastic models. Mr. CEMENT S has a suitable adhesion and strong strength because it contains high-quality resins. Pour the MC129 or MC130 into gaps of parts fit each other to glue the parts. MC129 has better capillary flow properties, quicker drying times, and strength in final bond versus other glues. The MC129 and MC130 are thin tip brush types designed for easy works. (The MC130 smells orange.) Tested and certified radiologically inert.
