Physical PropertiesHigh intensity
Phenolic resin for coated foundry sand should be selected around the shell-molding process and required binder performance. This yellow phenol-formaldehyde resin enquiry identifies CAS 9003-35-4 and EINECS 500-033-5. Define the grade and technical requirements for the sand system in which it will be used.
Specify the resin through its coated-sand function
Describe the sand, coating process and cure requirements relevant to the application. For a high-strength binder requirement, identify the test basis and acceptance needed for the selected resin grade. The process conditions and required result should guide the material evaluation rather than the chemical name alone.
- Identify the shell-molding and coated-sand process.
- Specify the resin grade and binder-performance requirements.
- Request grade-specific technical data and SDS.
- Describe sample evaluation and required material documentation.
- State the supply quantity and selected grade.
- Identify storage instructions required for material planning.
Agree the material-data basis for the selected grade
A purity reference of 99.99 is supplied, with the basis and unit to be established through the grade specification. Request the data relevant to the intended foundry use, including the properties used for acceptance. Chemical identifiers help identify the enquiry, while the grade-specific technical data defines the actual resin supply.
Use the sample to evaluate process performance
Samples can be provided for the requested evaluation. Define the coating and cure conditions under which the resin will be assessed and the results required before a production order. Agree the applicable storage and shelf-life instructions for that grade so material handling and process planning refer to the same supply specification.
