NixStix CB is a release for cold–box and no-bake mold and core boxes. NixStix CB incorporates a blend of silicones in a medium liquid hydrocarbon mixture. You can apply this by spraying, brushing, or wiping in a uniform coat to ensure a consistent release. When using NixStix CB, you can expect multiple releases between applications. The spray should be directed into the core box cavity to avoid parting line build-up. NixStix CB is very low in volatile organic compounds.
