Title:
RESIN COMPOSITION FOR SHELL MOLDING AND RESIN-COATED SAND OBTAINED USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/047893
Kind Code:
A1
Abstract:
Provided is a resin composition for shell molding, which is capable of advantageously improving the blocking resistance of RCS by heightening the fusing point of the RCS, while improving the disintegratability of a mold in a low temperature range. Also provided is RCS which is obtained using this resin composition for shell molding and has excellent mold formability and casting workability. A resin composition for shell molding, which contains a phenolic resin as a resin binder component, and which additionally contains a non-halogen phosphoric acid ester that is composed of one or more phosphoric acid ester compounds wherein no halogen atom is bonded in each molecule, while having a P content of 14% or more and a viscosity of 150 mPa·s/25°C or more.
