Product Operate Guide

Step 1: Make sure compatibility and adhesion between sealants and adhesive material before using.

Step 2: The sealant displays excellent adhesive effect in the clean environment with temperature of 4℃-40℃and Relative Humidity(RH)of40%-80%.

Step 3:Surface cleaning for bond substrates, clean up the dirt, grease and other contaminants, then affixedtemporary protective tape.

Step 4: According to the size you want, cut out sealant mouth.

Diameter of Gun nozzle should be smaller than the thickness ofthe sealant injection place, it makesnozzle can stretch into the 1/2 depth of the sealant injection place. Start to inject sealant whensubstrate surface is completely dry, Extrusion and injection of sealant shall be continuous ,whichmakes sure the extrusion of sealant is continuous and uniform cylinder, the move the gun slowly anduniformly, make sure the substrate interface is full of silicone sealant. Quick move is not allowed forthe gun, it will cases bubbles or holes.

Step 5: Decoration should be carried out when the injection is finished, and remove temporary protective tape.

FAQ

FAQs

What is the precise mixing ratio requirement for the two components?

The system requires a fixed 10:1 base-to-catalyst ratio, critical for achieving proper cross-linking and long-term durability.
How quickly must the mixed material be used after dispensing?

The pot life is 45 minutes at standard workshop conditions (23°C, 50% RH), requiring efficient application within this window.
Can existing equipment be used for application, or is specialized machinery needed?

Compatible with standard two-component meter-mix dispensing systems, though equipment calibration is recommended for optimal performance.
Does the cured sealant retain flexibility under constant structural stress?

The engineered polymer matrix maintains elastic recovery through continuous thermal cycling and mechanical pressure variations.
