JY 968 Fireproof Silicone Sealant

Features

1.Intumescent Fire-Blocking Performance

When exposed to intense heat, the sealant expands to create a robust, insulating char layer that effectively obstructs the spread of flames and superheated gases.

2.Intumescent Fire-Blocking Performance**

When exposed to intense heat, the sealant expands to create a robust, insulating char layer that effectively obstructs the spread of flames and superheated gases.

3.High-Strength Multi-Substrate Adhesion

Develops powerful bonds to various construction materials—including concrete, plasterboard, and metals—often without requiring primer.

4.Preferred Colors for Efficient Application

red and white variants are preferred by professionals for their practical benefits: the bold red ensures precise application control, while the neutral white provides a discreet, aesthetically pleasing finish on light-colored surfaces.

Application

Maintaining Fire Barrier Integrity: Sealing joints and penetrations in fire-rated walls, floors, and ceilings to prevent the spread of flames and hot gases.

Sealing Service Penetrations: Fire-proofing openings around electrical conduits, pipes, and ventilation ducts that pass through fire compartments.

Fire-Rated Glazing and Curtain Walls: Installing and sealing fire-resistant glass panels and within curtain wall systems to maintain their protective rating

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.
