General Purpose Silicone Sealant (GP300+)
Main purposes:



For sealing doors and windows.
For all the glass-related building.
For Gap filling in interior applications.
Characteristics:
One-component, acetic cured, RTV, low-modulus.
- Easy to use, cured quickly, good weatherability .
Good adhesion to many building materials.
Colors available :
ccc
Application:
Clean with solvents such as toluene or acetone to keep the substrate surfaces completely clean and dry;
For better appearance cover outside of joint areas with masking taps before application;
Cut nozzle to desired size and extrudes sealant to joint areas;
Tool immediately after sealant application and remove masking tape before sealant skins.
Unsuitable for curtain wall structural adhesive;
Unsuitable for the airproof location, because it is required to absorb moisture in air to cure for the sealant;
Unsuitable for the frosty or moist surface;
Unsuitable for the continually soggy place;
Can’t be used if the temperature is below 4°C or above 50°C on the surface of the material.
Shelf life: 12 months if keep sealing, and stored below 270C in cool, dry place after the date of production.
Volume: 300ml
