Product Description
LOCTITE SI 5421, Silicone, Bonding or Gasketing, Flexible, Formed-in-place, Electrically Conductive Adhesive. It enhances the load bearing & shock absorbing characteristics of the bond area.
LOCTITE SI 5421 is used for automotive sensor bonding and gasketing of EMI/RF shielded enclosures. It is a room temperature vulcanizing adhesive that moisture cures in 24h to make a flexible, formed-in-place, electrically conductive bond.
Surface Cure
- LOCTITE SI 5421 becomes tack free on exposure to atmospheric moisture within 1 hour at 23±2°C / 50±5%RH.
Technical Specifications
| General Properties | |||||
| Specific Gravity Specific Gravity Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless. | 3.05 | ||||

| Thermal Conductivity Thermal Conductivity Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system. | 0.81 W/m.K | ||||
| Electrical Properties | |||||
| Volume Resistivity Volume Resistivity Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface. | 1.0x10-2 Ohms⋅cm | ||||
| Mechanical Properties | |||||
| Elongation Elongation Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break. | 40 % | ||||
