Product Description
LINQBOND SO-168CM is a organotin and dibutyltin (DBT) compound-free, moisture-curing, modified silicone adhesive, engineered to comply with stringent EU regulations. This advanced formulation utilizes alkoxy functional groups to facilitate ambient temperature curing via atmospheric moisture. SO-168CM has rapid curing profile and odorless features. This adhesive exhibits superior cohesive and adhesive strength compared to conventional silicone-based counterparts, making it optimally suited for demanding critical casting and bonding applications within the 3C (Computers, Communications, and Consumer Electronics) industry.
Product Key Features:
- Moisture-Curing Mechanism: Cures via reaction with ambient humidity without the need for external heat or activators.
- Fast Curing Speed: Makes production throughput more efficient and reduces cycle times.
- Enhanced Adhesion Strength: Provides robust and reliable bonding for critical applications.
- Optimized for 3C Industry: Specifically designed to meet the performance demands of electronics and consumer goods manufacturing.
Applications
- Critical casting
- Structural bonding in electornics

| 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. | 1.65 | ||||

| Thixotropic index Thixotropic index Thixotropic Index is a ratio of a material s viscosity at two different speeds in Ambient temperature, generally different by a factor of ten. A thixotropic material s viscosity will decrease as agitation or pressure is increased. It indicates the capability of a material to hold its shape. Mayonnaise is a great example of this. It holds its shape very well, but when a shear stress is applied, the material easily spreads. It helps in choosing a material in accordance to the application, dispense method and viscosity of a material. | 3 | ||||
| Viscosity Viscosity Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application | 150,000 - 300,000 mPa.s | ||||

| Glass Transition Temperature (Tg) Glass Transition Temperature (Tg) The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs. | -40 °C | ||||

| RoHS Compliant RoHS Compliant RoHS is a product level compliance based on a European Union Directive which restricts the Use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS). Products compliant with this directive do not exceed the allowable amounts of the following restricted materials: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), with some limited exemptions | Yes | ||||
Additional Information
Directions for Use
- Apply to a clean surface which should be free of dirt, grease or mold release. In many cases, a simple solvent wipe is sufficient.
- Pour or brush this product onto the substrates. It is not recommend to stir it onto the substrates to avoid formation of air bubbles. This product will be cured through air-drying but propeties depend on its thickness, curing temperatrue, and relative humidity.
- When casting in thicker components or devices, the resin might not be cured thoroughly at the bottom of the components or devices because the bottom resin is difficult to cure with the moisture. It is recommended to extend the cure time, so that the moisutre can be diffused from the top to the bottom. Another solution is to cast the components or devices twice. Cast the resin to half height of components and devices first. When the surface is almost dry and tacky, cast the resin for a second time.
- Use this product as soon as possible after opening the original package. When not in use, please replace the lid tightly and store in a cool and dry place.
- Cure time depends on part geometry, materials to be bonded, bondline thickness, and humidity. Cure schedule should be in accordance with actual specifications of production parts and equipment.
- Cured product is safe for human skin contact.
