1. Characteristics.
KaLi 8300 belongs to RTV-1. Good extrusion and thixotropy between 40C, -+400C, .
Easy to use;
Neutral curing, non-corrosive to metal, coated glass, concrete, marble, granite etc.
No inert low-molecular-weight components in the formulation like plasticizer and
Pollution-free to porous materials like marble, granite. Excellent sealing and decoration.
Common silicone sealant, especially silicone weather-proofing sealant, easy to bring on pollution, is unsuitable for stone curtain wall.
Excellent adhesion to all type marble, granite and cement materials;
Release low-molecular-weight alcohol and no unpleasant odor during cure.
-- Excellent resistance to weather, UV, ozone, water;
-- Excellent resistance to low and high temperature change.
-- No fragility, rigidification or crack at -500C, and no softening, degradation at 1500C,
When cured. It always keeps good elasticity;
-- Good compatibility with other neutral silicone sealants.

2. Purpose:
-- Weather sealing for stone curtain wall joints and precast slab joints;
-- Sealing for concrete expansion joints in tunnel and pavement;
-- Adhesion and sealing in expansion joint for ceramic engineering;
-- Joint sealing between stone and other materials like glass, metal, plastics etc;
-- Many other uses.

3. Application Standard: ASTM C920-01

4. Restriction of Usage:
-- Cannot be used as structural sealant;
-- Unsuitable for all kinds of material that can effuse grease, plasticizer or solvent;
-- 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 or moist place.
-- Cannot be used if the temperature is below 40C or above 400C on the surface of
The materials.
