DeFelsko PosiPatch SST Starter Kit | Standard Magnetic Ring | Defelsko

TUTORIALS

To perform soluble salt contamination testing, position the PosiPatch system on the metallic surface using the rigid magnetic ring to keep the patch properly secured and sealed throughout the procedure.

Introduce the extraction solution into the PosiPatch according to the applicable test procedure, allowing the soluble salts present within the defined area to dissolve. After extraction, the solution can be analyzed using a compatible conductivity meter and probe.

The reusable system eliminates the need for traditional adhesive patches and prevents adhesive residue from remaining on the surface after testing. The rigid ring is especially suitable for flat surfaces or surfaces with large diameters.

FUNCTION DETAILS

Soluble salt testing
Designed to assist in determining soluble salt contamination present on surfaces before the application of paint systems and protective coatings.

Reusable PosiPatch system
Uses the PosiPatch system as an alternative to conventional adhesive Bresle patches, providing greater convenience during testing and allowing the system to be reused according to applicable guidelines.

Rigid magnetic ring (Standard)
The rigid magnetic ring keeps the PosiPatch securely attached directly to metallic surfaces and is especially suitable for flat surfaces or surfaces with large diameters.

No adhesive residue
Because the system is secured using a magnetic ring, it eliminates the adhesive residue normally associated with traditional self-adhesive patches.

Sealing during testing
The system provides secure attachment of the PosiPatch to the surface, helping keep the extraction solution confined within the test area throughout the procedure.

Reliability and repeatability
The system is designed to provide consistent and repeatable testing, assisting in the control of surface contamination before coating application.

Conductivity measurement compatibility
Designed for use with compatible conductivity meters and probes for analysis of the solution extracted from the surface.

DOCUMENTS

The PosiPatch SST Starter Kit – Rigid Ring is designed for soluble salt contamination testing on surfaces using the extraction principle of the Bresle method. The system can be used in procedures related to ISO 8502-6 for contaminant extraction and ISO 8502-9 for determining soluble salts by conductivity.

The PosiPatch system uses a rigid magnetic ring for attachment to metallic surfaces, eliminating the need for adhesive and providing a practical and reusable alternative for surface contamination inspections.

REPLACEMENT PARTS

The system uses specific components and consumables for testing. The PosiPatch is designed to be reusable, reducing the consumption of disposable patches and eliminating adhesive residue on the surface.
