Product Description

Long service life GP none Acetic Silicone Sealant

DF-821 one component weatherproof sealat is a one-component, high-elasticity, low-modulus (LM) silicone weather-resistant sealant for use in all forms of curtain wall construction, especially in high-rise building façades and complex structures form. It can be easily extruded at most ambient temperature and reacted with moisture in the air to form a durable silicone sealant. Due to its ability to withstand high and low temperature alternating deformation and deformation within its displacement capacity, it can be used with structural glues that meet the construction industry standard JG/T 475 or European standard ETAG 002 to provide 25 years of quality assurance.

Application

Mainly applied in the waterproof, weatherproof sealin of glass curtain wall, aluminum curtain wall and other building curtain wall.

Application instructions

NOTE: Before application, remove all impurities and contaminants such as grease, dust, water, frost, surface contamination, residual sealant, glazing attachments and protective coatings that remain in the joints and fittings.


1. Install the backing material, isolation spacers, spacer spacers and tapes as required. Masking tape should be used in the area connected to the seam to ensure the clean and beautiful appearance of the sealant.
2. For non-porous materials, it is usually not necessary to apply primer to have good adhesion. However, for some porous materials, primer may be needed to ensure good adhesion. It is recommended that before the project starts. Do a cohesive test.
3. Continuously squeeze and fill the DF821 silicone weatherproof sealant (the sealant can be constructed using pneumatic glue guns and other glue injection equipment). When using a pneumatic gun, adjust the operating pressure to prevent air bubbles from being generated during the injection.
4. When the surface of the sealant has not been skinned, the sealant is flattened on the backing material and the surface of the joint with appropriate force, and the surface of the sealant is smoothed.
5. After the leveling is completed, immediately remove the masking tape. Do not use liquids such as water, soapy water or alcohol to help level.

 at the same time. To make the silicone more delicate.

Finer grinding

After agitated, the sealant will be extruded to the storage tank, the sealant will flow via pipe to the twin screw extruded.
The sealant will be finer grinded, before packing.
