OLV4800 Silicone Weatherproofing Building Sealant

Short Description:

OLV4800 Silicone Weatherproofing Building Sealant is a one-component neutral curing silicone sealant with excellent adhesion, weatherability and elasticity for weather sealing in curtain wall and building facades, especially suits applications in the areas with large difference in temperature and low humidity. It easily extrudes in any weather and quickly cures at room temperature by reaction with moisture in the air to form a durable silicone rubber seal.
Because of its excellent adhesive qualities, OLV4800 provides the long-term performance required for demanding weatherproofing applications.

Main purposes

1. Professional used for curtain wall non-structural lap and docking sealing, including glass, aluminum plate, aluminum plastic plate, steel structure body and other high-rise curtain wall weather sealing.
2. Weather sealing in metal (not including copper), glass, stone, aluminium panel, and plastic
3. Joint sealing and multi-purpose sealing safety requirements.

Characteristics

1. One-component, neutral-cured with excellent adhesion, weatherability and elasticity for weather sealing in curtainwall and building facades;
2. Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes;
3. With good adhesion and compatibility with most building material;
4. Remain flexible over a temperature range of -400C to 1500C;
5. Resists severe environmental conditions such as wind loading, wind driven rain, snow and sleet.

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

Shelf life: 12 months if keep sealing, and stored below 27⁰C in cool, dry place after the date of production.
