Automobile lamp sealant
Product characteristics and applications:
DTT-378M-2 is a one-component, room temperature cured silicone rubber, which belongs to dealcoholization curing, with very low volatile organic matter, odorless after complete curing, has excellent bonding properties, excellent high and low temperature resistance, and little change in properties in the range of -50 +200.
DTT-378M-2 is mainly used for bonding and sealing of lighting, various glass, aluminium, engineering plastics, automobiles and building materials; it has good bonding with most materials (glass, aluminium, ceramics, ABS, PBT, PET, PVC and PC), and generally does not use undercoat.

Usage method:
1) Clean surface: Clean up the surface of the sticky or coated material, remove rust, dust and grease, etc.
2) Sizing: Cut off the cap of rubber hose, cover the tip (cut the tip to the appropriate size), squeeze the glue onto the clean surface with a rubber gun, make it evenly distributed, and close and fix the adhesive surface.
3) Curing: Place the coated parts at room temperature and let them self-curing. The curing process of this adhesive is a gradual curing process from outside to inside. Under room temperature and 50% relative humidity, the depth of curing will be about 2-4 mm in 24 hours. When the temperature is low or the humidity is low, the curing time will be prolonged.
4) After the operation is completed, the unused glue should be sealed and stored. When used again, if there is a little crust at the seal, it can be removed without affecting normal use.
Storage, transportation and precautions:
1) Keep away from children. If you touch your skin carelessly, wipe it clean, then rinse it with clean water; if you touch your eyes carelessly, rinse it with clean water immediately and go to the hospital for examination.
