DF-802 is a two-part silicone sealant for secondary sealant in both structural and non-structural insulating glass units.
It is RTV fast-cure neutral curing silicone sealant with unprimed adhesion to a wide range of coated and annealed glass.
The sealant cures to become a high-modulus silicone rubber suitable for insulating glass application.
The sealant contributes to the superior productivity and high reliability.
The sealant has excellent resistance to high&low temperature and air aging.
The sealant has no corrosion to the surface, no pollution to the environment.
The sealant Consistent with standard of JC/T486

5.General properties

6.General instruction for use
1. Adhesion and compatibility must be tested before the commencement of any sealant application.

2. Before applying the sealants, ensure that all the areas to be sealed are clean and dry.

3.The DF802 shoud be mixed and dispensed with airless,metered pumping equipment. Hand mixing of the base and catalyst is not approved.

4. The applicator must conduct:
a. Butterfly test to ensure proper mixing
b. Adhesion test to ensure proper adhesion to the
substrate surface.

5. The sealant should be tooled immediately after the
application.

7.Limitations
1. DF-802 is not approved for structural glazzing applications.
2. DF-802 must not be used in food, medical or pharmaceutical applications.
3.It is users responsibility to confirm DF802 meets the requirements of the application.
4. Materials that cannot be used to exude grease, plasticizers or solvents
5. Not suitable for frosted or wet surfaces
6.The surface temperature of the construction material should be between 15°C and 27°C.Itis not suitable for construction when the surface temperature of the material is lower than or exceeds 40℃C.
7.Not suitable for use in tight airtight places
8.Not suitable for continuous water immersion
or perennial wet places

8.Storage conditions
DF802 should be stored in dry areas and temperature below 25C

9.Shelf life
12 months after production date under the above storage conditions in the original unopened container.

10.Safety and hygiene
1. Uncured DF-802 may cause skin irritation. When handling the products, take care to avoid contact with the skin and mucous membranes by wearing protective glasses and protective gloves. In case of skin contact, immediately wipe off with dry cloth and then flush thoroughly with running water.
When using, be careful not to rub eyes with hands. In case of accidental eye contact, flush immediately with plenty of clean water for at least 15 minutes and then seek medical attention. Contact len wearers must take special care. If the products get into the eye, the contact lens may become stuck to the eye.

2. Be sure to provid adequate ventilation when using the products. During curing, a small amount of Methanol gas is gradually generated. If you become uncomfortable with it, move to an area with fresh air immediately.

3.KEEP OUT OF REACH OF CHILDREN.
