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 are phenol-free, offer excellent mould strength, exceptional casting finish for copper alloys and steel and produce lower levels of casting fume.
​
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.

Winterbond 156
Moulds and Cores
Winterbond 156 is a premium grade sodium silicate binder that can be cured with an ester/ hardener. It produces very high mould strengths at low addition percentages with superior surface finish. Very high, hot face strengths eliminate veining on copper alloys castings. Contact Us for compatible John Winter esters.
Air Setting Silicate Hardener
Winset Hardener
Moulds and Cores
Winterbond 156 silicate can be set with CO2 but are best used with an ester/ hardener. The Winset Hardeners are added at very low levels (just 10%) compared to phenolic resins (22%) so are very cost effective.
