I.Product Features
NQ-9900C is a one-component acetic acid curing type room temperature vulcanizing silicone sealant. This product has high strength and good adhesion. It has good adhesion to various metals such as aluminum, copper, stainless steel, silica gel, rubber, etc. It has excellent dielectric properties and good heat resistance. The general operating temperature range is -60°C to 200°C. It is mainly used for high-strength and low-odor bonding of silica gel to silica gel. It fully complies with the requirements of the EU ROHS Directive.

III. Technical Parameters
Before Curing
- Appearance: Translucent semi-fluid
- Relative density (g/cm³): 1.08 – 1.12
- Surface dry time (min): ≤15
- Complete curing time (d): 3 – 7
After Curing
- Tensile strength (MPa): ≥2.0
- Elongation at break (%) : ≥300
- Shear strength (MPa): ≥2.0
- Hardness (Shore A): 20 – 35
- Temperature resistance range (℃): -60 – 200
- Volume resistivity (Ω·cm): 1.0×10¹⁵
- Dielectric strength (kV/mm): 18
The above performance data were all measured after the product was cured for 7 days at 25°C and a relative humidity of 55%. Our company shall not be liable for any differences in data caused by different testing conditions or product improvements.
IV.Application Process
- Clean the surface: Thoroughly clean the surface of the object to be bonded or coated, and remove rust, dust, oil stains, etc.
- Apply the adhesive: Unscrew (or cut open) the cap of the adhesive tube, and squeeze the adhesive onto the cleaned surface, ensuring an even distribution.
- Curing: Place the bonded or sealed component in the air and let it cure naturally. The curing process is from the surface to the interior. Within 24 hours (at room temperature and 55% relative humidity), the adhesive will cure to a depth of 2 to 4 mm. If the application position is deep, especially in areas that are not easily exposed to air, the time for complete curing will be extended. If the temperature is low, the curing time will also be extended. It takes more than 7 days for a 6-mm-thick sealant to completely cure.V.Precautions
After applying the adhesive, immediately tighten the cap of the unused adhesive and store it in a sealed manner. When using it again, if there is a small amount of skin formation at the sealing opening, simply remove it, which will not affect normal use. During the storage of the adhesive, there may also be a small amount of curing at the tube opening. After removing it, the adhesive can be used normally without affecting the product performance.
