International Classification:

C08J 6110

US Classification:

523145

Abstract:

A process for improving the flowability of resin coated sand which comprises the use of a flow promoter with the mixture of sand and resin. Also provided is a foundry mix comprising foundry sand, a resin binder and the flow promoter, as well as a process for making foundry cores and molds using the foundry mix. The resins are ester-curable alkaline phenolic resole resins. The flow promoter is selected from the group consisting of fatty acids, fatty alcohols, fatty amines, fatty amides and fatty alkanolamides.

International Classification:

C04B 1204

US Classification:

106 382

Abstract:

No-bake inorganic binder compositions for binding particulate material and methods for curing such inorganic binders. The inorganic binder compositions are composed of silicate and phosphate components. The no-bake compositions further contain curing catalyst such as a catalyst selected from the group consisting of aliphatic carbonates, cyclic alkylene carbonates, aliphatic carboxylic acid esters, cyclic carboxylic acid esters, phosphate esters and mixtures thereof. The composition produces a binder having the advantageous strength properties of a silicate binder system with the water breakdown properties of a phosphate binder system. Thus, relative to an all-silicate binder system, the present invention has improved mechanical shakeout and improved water collapsibility. Also, relative to conventional all-phosphate binder system, the present invention has superior hot strength, i. e. , the foundry cores and molds do not soften at elevated temperatures.

Borden, Inc. - Columbus OH

International Classification:

B22C 122

US Classification:

523145

Abstract:

A phenolic resole resin for use as a foundry binder which has been internally modified to reduce its hot strength and thereby enhance its shakeout property is disclosed. The resin is the reaction product of a phenolic compound; a dialdehyde; and formaldehyde. A process of preparing such resin is also disclosed, comprising first reacting the phenolic compound and the dialdehyde, and subsequently reacting the product with the formaldehyde. The resin may be, in a preferred embodiment, an ester-curable alkaline phenolic resin. Also disclosed are a raw batch formulation including the resin of the invention, and foundry articles prepared therefrom.
