Main purposes

1.Designed for sealing non-structural curtain wall joints;
2.For marble, granite, concrete, ceramic, most plastics, tile & brickworks;
3.Other general exterior wall gap-filling waterproof purpose.

Characteristics

1.One-component, neutral cured, excellent performance in sealing;
2.Excellent weatherability, anti-UV, anti-ozone and waterproofing;
3.On curing will form a strong bond to most common building components without the use of primer.

Application

1. Clean with solvents such as toluene or acetone to keep the substrate surfaces completely clean and dry;
2. For better appearance cover outside of joint areas with masking taps before application;
3. Cut nozzle to desired size and extrudes sealant to joint areas;
4. Tool immediately after sealant application and remove masking tape before sealant skins.

Limitations

1. Unsuitable for curtain wall structural adhesive;
2. Unsuitable for the airproof location, because it is required to absorb moisture in air to cure for the sealant;
3. Unsuitable for the frosty or moist surface;
4. Unsuitable for the continually soggy place;
5. 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
