Packing Specification


Packed in a net capacity of 300ml per cartridge or as required by the customer.




Store in a cool, dry and ventilated place. The storage period is 12 months from the date of manufacture.


Use Limit


It should not be used in dense and non-ventilated places, not suitable for continuous water immersion, and can not be used as the structural sealant. When the material surface is lower than 4 °C or exceeds 50 °C, it is not suitable for application.




Surface treatment

The substrate surface should be dry clean and free from rust, dust and oil, etc.; the cleaning solvents that can be used include isopropyl alcohol and acetone; the majority of the substrate is perfectly bonded except PTFE, polypropylene, polyethylene and similar materials.


The sealant is squeezed onto the cleaned surface with a sealant gun to make it evenly distributed; if the potting position is deep, the time for complete curing will be prolonged; if the temperature is lower, the curing time will be prolonged.


In order to achieve the best bonding effect, it is recommended to apply the special primer from Guibao Company; the surface of the substrate is treated with a solvent, and the primer is dipped, painted or sprayed on the surface of the substrate to form a film; the silicone sealant is 

applied to the surface of the substrate; the special application is carried out in three steps of drying, humidification and high temperature drying to ensure the stability of silicone sealant curing.

Safety Instructions

Avoid contact with eyes before curing; if contact with eyes, please rinse with plenty of water and consult a doctor; uncured products should avoid contact with children; ventilation should be observed in the application and curing area.
