A proven no-bake system for high-volume iron casting
Phenolic Acid Cured resin is a two-component, self-setting no-bake binder system built around an acid-catalysed phenolic (novolac-type) resole resin. Part I is the liquid phenolic resin; Part II is a liquid acid catalyst that controls how fast the sand mixture develops handling and full strength. Because the catalyst percentage can be adjusted, foundries can fine-tune work time and strip time to match ambient temperature, sand type and production speed.
At BR Chemicals, every batch of our Phenolic Acid Cured resin is tested in-house for viscosity, solid content and reactivity, so foundries get the same bench life, tensile strength and finish on every drum — whether it's a single trial batch or a full tanker delivery.
Built for productivity on the moulding floor
An acid-cured system chosen for its speed, strength and cost-efficiency on high-volume iron casting lines.
Fast, Adjustable Cure
Catalyst percentage can be tuned to give fast, medium or slow strip times to match your production schedule.
High Green & Cured Strength
Delivers the tensile and compressive strength needed for dimensionally accurate, defect-free castings.
Cost-Effective Chemistry
A proven, economical no-bake system that keeps binder cost per mould low without compromising quality.
Good Sand Reclamation
Compatible with thermal and mechanical reclamation practices, helping reduce new sand consumption.
Applications
- ✓ No-bake moulding for cast iron (CI) castings
- ✓ SG (ductile) iron casting production
- ✓ Ni-Hard and other abrasion-resistant iron castings
- ✓ Non-ferrous casting applications
- ✓ High-volume, cost-sensitive moulding lines
- ✓ Jobbing foundries needing flexible strip-time control
What makes up the system
Phenolic Novolac Resin
An acid-curable phenolic resole resin — the base binder component, mixed with sand ahead of the catalyst.
Liquid Acid Catalyst
Controls gel and strip time — dosage is adjusted for fast, medium or slow grades based on shop temperature.
No-Bake Sand Binder
A self-setting mould/core system with high strength, good flowability and easy shakeout after pouring.
