RTV Silicone
Application scope:
Wesbond 9040 has stable performance, long storage period, non-toxic, solvent-free, non corrosive, non flammable, non explosive, high and low temperature resistance, aging resistance, and excellent electrical insulation and arc resistance. It has good adhesion and bonding to both metals and non metals.
Purpose:
9010RTV silicone rubber is widely used as an adhesive, sealing, insulating, moisture-proof, and shockproof material for electronic components, semiconductor materials, electronic appliances, and other equipment. It is also used for waterproofing and sealing of electric heaters, electronic instruments, and sealing of electronic components. Specifically, it includes sealing of electric heating terminals, bonding of small motor magnetic tiles and metal shells, bonding and sealing of car lights, optical instruments and lenses, bonding of electronic instrument shells, insulation protection of motors, bonding and sealing of electronic components, etc.

usage method:
After general cleaning and drying of the components, the product is extruded from the metal hose and coated with glue. The glue comes into contact with moisture in the air and solidifies from the surface to the inside, with a maximum curing time of no more than 24 hours.
matters needing attention:
1. For temperature resistant components, they can be cured at room temperature first, and then treated in a damp oven at 50-100 ℃ for 4-8 hours to remove low molecular weight substances and fully cure to ensure the performance of the adhesive.
2. After use, the rubber hose should be tightly covered and can be stored for reuse.
