6. Usage Method
l The base materials and auxiliary materials selected for the project must be tested for adhesion and compatibility, and can be put into use only after passing the test.
l The design and construction of the project must strictly abide by the technical specifications stipulated by the state for relevant projects, and refer to the "GIRAFE 918 Silicone Sealant For Large Plate Glass Usage Guide".
l Air circulation should be maintained during construction and curing environments.
l The bonding surface of the substrate must be cleaned with cleaning solvents such as toluene, xylene or acetone.
l After the glue fills the joints, use a scraper to squeeze further inward to completely fill the joints with glue, and modify the glue surface before it solidifies.
7. Restriction of Usage
l Cannot be used on all material surfaces that will exude grease, plasticizers or other organic solvents
l Not suitable for use in airtight places, because silicone structural sealant needs to absorb moisture in the air to cure
l Not suitable for use on frosted or damp surfaces
l Not suitable for metal coated glass assembly.
l Not suitable for use in contact with marble, granite and other alkaline substances
l It is not suitable for construction when the surface temperature of the material is lower than 6°C or higher than 40°C
8. Packaging

l Solving problem in the course of using timely.
12. Interface Design & Construction Methods:
Please refer to "GIRAFE Silicone Sealant Construction Guide"
13. Safety Tips:
l Silicone sealants release volatile compounds during the curing process, which may be harmful to health if inhaled for a long time, so good ventilation should be maintained in the construction site.
l The cured silicone sealant no longer releases harmful substances and will not have any harmful effects on the body.
l Keep uncured silicone sealants out of the reach of children. If they accidentally get into the eyes, please rinse with plenty of water and seek medical attention.
14. Guarantee:
l Our company has passed IS09001 and 15014001 management system certification, and strictly produces and controls product quality according to the requirements of 1S09001 quality system. In August 2006, it was approved as a certified enterprise for the production of silicone structural sealants for construction.
l After the user purchases the product and determines the construction unit and project, our company will issue a quality guarantee for silicone structural sealants.
15. Maintenance:
l Generally no maintenance is required. If the silicone structural sealant seam is damaged, remove the ineffective silicone structural sealant, clean the substrate surface, and then fill it with silicone structural sealant.
l GIRAFE brand silicone structural sealant can adhere well to the cured silicone glue.
