A wet friction material is disclosed bonded to a plate for transmission of motion, with the friction material made up of a porous fiber substrate, which is at least partially impregnated with a catalyzed resorcinol diglycidyl ether resin to improve properties.

Porous wet friction material utilizing a compliant epoxide resin binder system

This invention relates to foundry binder systems, which will cure in the presence of sulfur dioxide and a free radical initiator, comprising (a) an epoxy novolac resin; (b) preferably a bisphenol F; (c) an acrylate; and (d) an effective amount of a free radical initiator. The foundry binder systems are used for making foundry mixes. The foundry mixes are used to make foundry shapes (such as cores and molds) which are used to make metal castings.

Cold-box foundry binder systems

This invention relates to erosion resistant foundry binder systems, which will cure in the presence of sulfur dioxide and a free radical initiator, comprising (a) an epoxy resin; (b) a multifunctonal acrylate; (c) a phenolic resin that is soluble in (a) and (b); and (d) an effective amount of a free radical initiator. The foundry binder systems are used for making foundry mixes. The foundry mixes are used to make foundry shapes (such as cores and molds) which are used to make metal castings.

Erosion-resistant cold-box foundry binder systems

This invention relates to foundry binder systems, which will cure in the presence of sulfur dioxide and a free radical initiator, comprising (a) an aliphatic epoxy resin; (b) a multifunctional acrylate; and (c) an effective amount of a free radical initiator. The foundry binder systems are used for making foundry mixes. The foundry mixes are used to make foundry shapes (such as cores and molds) which are used to make metal castings, particularly aluminum castings.

Cold-box foundry binder systems having improved shakeout

This invention relates to foundry binder systems, which will cure in the presence of sulfur dioxide and a free radical initiator, comprising (a) an epoxy resin; (b) an acrylate; (c) an alkyl silicate; and (d) an effective amount of a free radical initiator. The foundry binder systems are used for making foundry mixes. The foundry mixes are used to make foundry shapes (such as cores and molds) which are used to make metal castings, particularly ferrous castings.
