602 identifies this industrial calcium carbonate white powder for silicone-sealant and adhesive formulation enquiries. Stated purity is 95%-99%, with the actual particle characteristics and formulation response to be established for the system under consideration.
Define two different sealant questions
Uncured handling and cured adhesion need separate evaluation criteria. Describe the sealant system and the behaviour required before choosing a test programme. A carbonate model designation does not demonstrate enhanced thixotropy or adhesion to a particular substrate.
- Before cure
- Agree which rheological and application characteristics will be examined.
- After cure
- Define the substrate, conditioning and adhesion assessment relevant to the project.
Request powder information for model 602
Obtain particle-distribution, surface-treatment and moisture information for the actual proposed grade. Ask for a measured whiteness report if appearance is part of the acceptance brief. Keep these reports tied to 602 rather than transferring a particle dimension or optical figure from a similarly named material.
Use a representative formulation to make the decision
Review the technical and safety documentation, then assess the powder in the intended sealant or adhesive under agreed conditions. Record the formulation and evaluation methods so that the result has a defined scope. No universal loading ratio, curing instruction or performance improvement is established here.
For subsequent enquiries, retain the tested model identifier and the relevant powder reports with the uncured and cured results. This makes it possible to distinguish a repeat material request from a changed formulation, substrate or qualification requirement.
