Product Description
JB8800 is a two component, neutral curing silicone sealant for structural applications. It has good adhesion with wide range of surfaces without the need of priming and professional quality.
Feature
◇ Two part, neutral, high flexibility, high modulus with excellent performance silicone sealant. ◇ Excellent adhesion to a wide range of curtain wall materials such as coated, enameled and reflective glass, anodized oxidation or coated aluminum and stainless steel.
◇ High level of mechanical properties with joint movement capacity of ±12.5%.
◇ Neutral cured, no corrosion, non poisonous.
◇ Excellent stability in a wide range temperature at -50℃~+150℃.
◇ Excellent weatherproof feature and a high resistance to UV radiation, high temperature and humidity.
Use Limitations
JB8800 silicone sealant should not be applied in the following conditions:
◇ To all surfaces that bleed oils, plasticizers or solvents, and some uncured or sulfurized rubber.
◇ To the unventilated space or the surface which can touch the food or water directly. Please read company’s technical files before application. Compatibleness test and bonding test must be done for construction materials before application.
Processing
◇ Please make sure A and B well-mixed before tooling. Use could also change the proportion of mixture to adjust curing speed according to physical demand (Volume ratio 8:1 ~ 12:1).
◇ It is not suitable for construction in high temperature - the surface temperature of outdoor base material is more than 40℃.
◇ The substrate to be in contact with the sealant must be clean, dry and free of all loose materials, dust, dirt, rust, oil, and other contaminants.
Storage
Storage period is 12 month from the date of manufacture when stored at dry and airy, below 30℃ conditions.
Safety notes
◇ During curing VOC is released. These vapors should not be inhaled for long periods or in high concentration. Hence, good ventilation of the work place is necessary.
◇ Should uncured silicone rubber come into contact with eyes or mucousmembranes, the affected area must be rinsed thoroughly with water as irritation will otherwise be caused.
◇ Cured silicone rubber, however, can be handled without any risk to health.
◇ Keep out of reach of children.
Mixture Ratio
Part A is white color, Part B is black color.
A/B - Volume ratio 10:1 ( Weight ratio: 12:1)
It is a two-component silicone that offers variable work life with high bonding strength to maintain the integrity of insulating glass unit, suits both commercial and residential IGU.
◇ Structural glazing applications such as: used for structural adhesion and seal the joints of the structural glass and metal in the factory or building site.
◇ Assembly of curtain walls glass material or stone material.
◇ Assembly of glass construction project.
◇ Assembly of windshield of car and ship.
