A Comprehensive Range of Foundry Resin Binders and Release Agents

There are a number of resin binders for making moulds and cores and they are split into 2 categories, Organic and Inorganic. Organic foundry resin binders offer excellent mould strength & casting quality, highly reclaimable and are suitable for a wide range of alloys from aluminium to steel. Inorganic foundry binders offer excellent mould strength and exceptional casting finish for copper alloys, iron and steel. They are especially good with copper alloys, produce lower levels of casting fume and are phenol free. 

To compliment a range of foundry resin binders John Winter manufactures multiple types of release agents so the surface finish of your mould and core production is of the highest quality. Also available is a range of Greensand Release Agents called PF875, PF880 and PF900, sold Globally.
