Nuomi silicone adhesive manufacturer continue to introduce new materials such as special additives, combined with advanced experimental equipment procurement, and constantly explore the performance boundaries of silicone rubber. With innovative procurement as the driving force, a series of silicone rubber products with unique advantages have been developed to meet the increasingly diverse needs of customers.
Bonding: Waterproof and moisture-proof bonding of metal and non-metal
materials and underwater instruments, elastic bonding of various electrical
sensors.
Sealing: Sealing the ends of electric heating pipes, chemical equipment, sight
glasses, electrical equipment, small appliances, power supplies, LED modules,
optical instruments, etc.
Coating: Insulation, moisture-proof and shock-proof, and protective for
various electronic components, semiconductor equipment and electrical
equipment.
Paste texture: semi-solid, easy to apply, fill or shape, suitable for uneven
surfaces.
High adhesion: Can firmly bond a variety of materials (such as metal, glass,
plastic, ceramic, wood, etc.) Flexibility: After curing, it still maintains a
certain elasticity and can adapt to thermal expansion and contraction or
vibration.
Waterproof and moisture-proof: It effectively isolates water and moisture and
is suitable for humid environments.
Weather resistance: Some products are resistant to UV rays, high temperatures
or low temperatures (such as -50℃ to 200℃).
Insulation: Some sealants have electrical insulation properties and can be
used in electronic equipment.
Surface treatment: Clean and dry the bonded surface to remove oil and dust.
Extrusion of colloid: Apply evenly with equipment or direct extrusion (tube
packaging).
Shaping and filling: Use a scraper or fingers (wearing gloves) to smooth the
colloid to ensure complete filling.
Curing time: It usually takes 1 minute to 30 minutes for the surface to dry,
and 24 hours for complete curing.
Cleaning up the remaining glue: It can be wiped with alcohol or special
solvents before curing; physical methods, such as blade removal, are required
after curing.
