Nuomi silicone adhesive manufacturer’s NM-501L-2 is a transparent liquid RTV-1 silicone adhesive. Its curing principle is to react with moisture in the air by condensation, and release low molecular substances during cross-linking. Different types of silicone cross-linking produce different byproducts, and the common ones are deoxime type, dealcohol type, and deacidification type. The deoxime type is more common, but it is somewhat corrosive to copper/PC; the dealcohol type is non-corrosive and suitable for electronics, metals and sensitive materials; the deacidification type is suitable for glass, ceramics, acid-resistant plastics, but it will emit a pungent sour smell. NM-501L-2 transparent liquid RTV-1 silicone adhesive is a dealcoholization product, you can choose as needed.
NM-501L-2 transparent liquid RTV-1 silicone adhesive is fully transparent and flowing, with low corrosion, strong adhesion, good weather resistance, good elasticity and sealing, etc. This transparent liquid RTV-1 silicone adhesive has bonding, fixing, sealing and waterproofing functions. Its surface drying time is 1 to 15 minutes, it is completely dry in 24 hours, and the strength reaches the highest after 7 days. After curing, it forms a flexible silicone layer, which can effectively resist shock, water and dust, and has a shelf life of 6 months.
This transparent liquid RTV-1 silicone adhesive is widely used. It can be used for circuit board protection, component sealing, LED packaging, headlight sealing, wiring harness fixing, sensor waterproofing, curtain wall joints, door and window sealing (especially scenes requiring neutral curing), solar photovoltaic module frame sealing, junction box waterproofing, and some dealcoholized silicones that meet biocompatibility requirements can also be used for medical equipment sealing.
This transparent liquid RTV-1 silicone adhesive should be used with attention when operating: in terms of surface treatment, the substrate should be clean and dry, and primer should be used to enhance adhesion when necessary; in terms of construction environment, the ideal humidity is 40% - 60%, and the temperature is 15℃ - 30℃. Low temperature or dry environment will slow down curing; safety protection is crucial, because the alcohol released by its curing is flammable, so it needs to be operated in a well-ventilated place and away from open flames; it needs to be sealed and stored in a cool place.
