A typical mixing ratio is 1-1.5% of resin to the amount of sand. The suitable amount of catalyst is 30-50% of the resin amount used.
The final mould strength depends on the binder, dosage, sand quality and curing conditions. A higher binder dosage is recommended for core moulding.
Different catalysts and their addition amounts are used to adjust the reaction speed. Higher amounts of catalyst speed up the curing process, but can lead to lower final strengths. Adding too much catalyst (over 60%) will result in a longer stripping time.
The sand must be free from alkaline impurities, preferably washed, cooled and dry. The temperature of the sand should not exceed 35 °C, in order to avoid premature curing. The higher the sand temperature, the less catalyst is needed and correspondingly, the lower the sand temperature, the higher dose of catalyst is needed. No-bake resin can be used as such with neutral and acidic sand grades (quartz, chromite, zircon etc.).
The information given in this product data sheet is based on our tests and our practical knowledge. The technical data is defined in standard conditions. Variations in local working conditions will affect the product performance and result. The result is also strongly affected by working methods. We guarantee the high quality of our products according to our Quality Management System. No liability can be accepted from incorrect use of the product or prevailing conditions, over which we have no control. Thus, we cannot be held responsible for the final result. The user of the product must test the product’s suitability for the intended application.
NOTE! When mixed together, resin-catalyst compound generates an intensive, heat-producing, explosion-like reaction. DO NOT MIX WITHOUT SAND! Should this happen, immediately add plenty of water to the mixture. Ensure sufficient ventilation in the working premises. Avoid unnecessary skin contact with and exposure to the fresh product: use safety gloves, safety glasses and protective clothing. Refer to material safety data sheet.
