JY620 Acrylic Sealant

JY620 acrylic sealant is a water based general-purpose, flexible sealant that is used for caulking, grouting, jointing and embedding in building construction.highly flexible and crack resistant it is easy to apply and compatible with most materials used in construction e.g. concrete, wood, brick, natural and artificial stone, glass, metal and sanitary-ware.The product proves particularly effective for interior gap sealing, drywall joint integration, and trim perimeter caulking where paintable finishes and minimal environmental impact are prioritized.

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

How does humidity influence the curing process?

High humidity extends curing time, while arid conditions accelerate water evaporation - optimal results occur at 40-70% relative humidity.
Can damaged sections be seamlessly repaired?

Fresh material bonds effectively to cured sections when properly primed, allowing for discrete spot repairs without full replacement.
What's the minimum curing period before paint application?

Allow 48 hours for complete moisture evaporation before painting, with extended time required in high-thickness applications.
How does temperature cycling affect long-term flexibility?

The polymer matrix maintains elasticity through seasonal variations, accommodating up to ±15% movement in properly designed joints.
