Filler Selection for Silicone Sealant Formulations

Silicone sealant fillers have to work with your balance of sag resistance, extrusion and cure behaviour. We compare calcium carbonate candidates within that complete system. The useful shortlist is built from moisture, treatment and trial evidence, rather than a nano designation used by itself.

Particle Designations with a Clear Meaning

The catalogue offers a concrete sealant comparison: 602-6 carries a 90±10 nm designation, 601 carries 120±10 nm with whiteness ≥94%, and 602 is another named sealant grade without a numerical size commitment in its description. We keep those designations separate from measured distribution and rheology.

Your trial and acceptance

A Complete-Formulation Trial

Keep the cure chemistry and formulation controlled while comparing the selected carbonate. Record uncured handling and cured performance separately, with the moisture and treatment information for the powder used. Use the storage period and acceptance method required by your own product brief.

Decision controls

Selection Priorities

Check 01

Match the measured dimension

A nanometre designation is not automatically a D50 or D97 measurement.

Check 02

Balance application behaviour

Evaluate sag resistance and extrusion together instead of choosing only the thickest uncured material.

Check 03

Retain the cured tests

Include the substrate and conditioning relevant to adhesion and the intended service.

Resolve the relevant gaps before extending a sample result into a supply decision.

From sample to supply

A Grade for the Tested System

The repeat-order brief should name 601, 602 or 602-6, the agreed powder limits and the formulation evaluated. Confirm package protection and supply terms for that grade. A change in treatment, moisture requirement or sealant chemistry deserves a defined review.
