Liquid sodium silicate / foundry binder is quoted from the multi-product factory at zzhchem.com. This page is not a sodium metasilicate RFQ.
Liquid Sodium Silicate Foundry Binder
Foundries bind moulding and core sand with liquid sodium silicate, cured either by CO₂ gassing or by liquid ester (self-set / no-bake). The SiO₂:Na₂O ratio governs gassing speed, bench life, strength, and shakeout behaviour.
Updated
Short answer
Foundries bind moulding and core sand with liquid sodium silicate, cured either by CO₂ gassing or by liquid ester in self-set / no-bake systems. The SiO₂:Na₂O ratio governs gassing speed, bench life, strength and shakeout behaviour, so the cure route and target ratio have to be stated before a grade can be quoted. Zhongzhi Chemical supplies liquid sodium silicate across a 2.0–3.5 modulus range from China in drums, IBCs or bulk tanker, with SDS downloadable and TDS and COA on request.
How Sodium Silicate Is Used
- CO₂-cured sodium silicate sand for moulds and cores
- Ester-cured (self-set / no-bake) silicate sand systems
- Cold-box and heated-core silicate binder programs
- Refractory and repair pastes bound with silicate
Benefits for This Industry
- Ratio selection to balance gassing speed, strength, and shakeout
- Consistent liquid specification for repeatable core-room results
- Bulk IBC, drum, and flexitank supply for foundry consumption
- COA, MSDS, and TDS per shipment for process qualification
How Our Sodium Silicate Supports This Application
| Formulation need | Product feature | Value to your line |
|---|---|---|
| Match binder to the cure route | Modulus bands for CO₂ gassing versus ester no-bake | The right ratio for gassing speed or self-set |
| Balance bench life, strength and shakeout | Selectable SiO₂:Na₂O ratio and % solids | Tune core properties to your core-room practice |
| Repeatable core-room results | Consistent liquid specification | Predictable strength batch to batch |
| Foundry-scale consumption | Drum, IBC and flexitank supply | Bulk supply matched to foundry usage |
| Process qualification | COA, MSDS and TDS per shipment | Documentation for process qualification |
What We Need to Confirm Before Recommending a Grade
Grade selection for this application depends on your process, not on a catalogue number. Send these conditions with your enquiry and the recommendation comes back with the reasoning attached.
- Cure route
- CO₂ gassing vs. ester self-set — each needs a different ratio band.
- Ratio & solids
- Weight ratio and concentration drive bench life, strength, and breakdown at shakeout.
What this page does not claim
Performance in your formulation is established by your own trial, not by a supplier page. These are the limits we hold to.
- We supply the silicate binder raw material to specification; sand quality, additives, and shakeout are foundry process factors we do not certify.
Liquid sodium silicate is the foundry binder grade. Continue on zzhchem.com for a multi-product factory quote; use this site only if you need solid metasilicate.
