Modified polymer sealant samples should be tested under conditions that closely reflect the actual project. Check adhesion, curing, and joint movement to confirm suitability for concrete joints.
How to Test Silane Modified Polymer Sealant Samples
Check the Joint and Substrate
Test the MS hybrid sealant on the actual concrete or other substrates used in the project. Check joint width, movement, moisture, and surface condition.
Test Basic Performance
Check adhesion, curing, joint movement, weather resistance, extrusion, and tooling. Test the sample under conditions close to the actual application.
Check Application and Finish
Check bead shape, sag, tooling, color, and surface appearance before placing a bulk order.
Critical Sealant Tests Before Approving a Bulk Order
Sealant adhesion and compatibility to the substrates
Test the ms modified silane sealant on the actual concrete and other project substrates. Check whether it bonds well and remains firmly attached after curing. If a primer is required, test the complete primer-and-sealant system.
What to look for: Good adhesion, no peeling or separation.
Curing and Joint Movement
Check skin formation, curing time, and hardness under conditions close to the actual project. Install the sample in the intended joint size when possible and check its performance during expansion and contraction.
What to look for: Suitable curing time, good flexibility, no cracking or loss of adhesion.
Weather and Chemical Resistance
For exterior concrete joints, test the sealant under water, sunlight, and temperature changes. If the joint contacts cleanser or other chemicals, check compatibility before placing a bulk order.
What to look for: No cracking, softening, discoloration, or loss of adhesion.
Application and Packaging
Check extrusion force, bead control, sag, tooling, and cleanup during application. Also inspect the cartridge or sausage packaging for leakage, damage, labeling, and batch information.
What to Check Before Choosing an MS Polymer Sealant Supplier
Check the Technical Documents (TDS）
Before placing a bulk order, check the TDS, SDS, test reports, shelf life, storage conditions, and applicable certifications. Make sure the documents match the exact silane modified polymer grade.
Check Supply and Production Capability
Make sure the supplier can maintain consistent quality, color, packaging, and lead times for repeat orders. For OEM or private-label projects, also confirm MOQ, packaging, and customization requirements.
Keep an Approved Sample
Keep the approved sample, product code, color, batch information, TDS, and test results as a reference for future orders. This makes it easier to check consistency when the next shipment arrives.
