One part, excellent extrusion performance, easy to use.

Excellent weather resistance, thermal resistance, cold resistance.

No bleeding, good compatibility with a variety of surface coatings.

Non-silicone oil, no oil proliferation risks, no corrosive and pollution to the substrate material.

Have excellent water tightness, air tightness, special stress relaxation function and conformability to the displacement of seams.


Used for the non-structural sealing of the joints between walls and jambs.



During transportation and storage, please prevent sunlight or rain, keep away from fire, and avoid collision, kept in ventilated and dry place. The best storage temperature is 5 ~ 30.

The quality guarantee period is 12 months under normal transport and storage conditions.


Method of application:

Base treatment: Construction surface should be clean, hard, dry, no grease and dirt surfaces, such as mold release agents, film conservation and hydrophobing agent.

Packing backing material: Paste protective tape on both sides of parts of the joint, and packing backing material.

Brushing primer: This product generally does not need brushing primer. If necessary, brushing primers YS-207 on the base, to be able to cover the basic level prevail, starting to glue after the primer is dry.

Glue caulking: Sizing cracks use the glue gun with prepared sealants inhalation. Colloid should be higher than the surface of the substrate for the post-modification.

A modified closure: Pressing colloid to remove air bubbles with a blade in one direction, recycling the excess glue, and modifying plastic marble surface flat orslightly concave. Remove the protective tape after modification.
