Three Bond 2212B - 1K Epoxidharz (hoch TG) - 4 kg Dose

Three Bond 2212B – 1K epoxy resin (high TG) at a glance

The Three Bond 2212B is an 1K epoxy resin with high temperature capabilities (high TG). The black pigmentation not only provides an aesthetically unobtrusive potting compound but also increases UV and thermal stability in sensitive applications. With viscosity at 25 °C: 25 Pa·s and density at 25 °C: 1.39 g/cm³, it offers good flow at room temperature and creates a dense, stable potting base. The shelf life is 7 months.

As an epoxy resin, it is characterized by excellent electrical properties and low outgassing – ideal for potting and mounting in electronic components, housings and assemblies where heat and isolation properties are critical.

Suitable for potting and mounting in electronics and industrial applications

Electronics potting

Due to high TG properties, the material remains stable at elevated temperatures and reduces the risk of delaminations under electronic components. The shear strength of 40 MPa provides mechanical reliability when enclosing or potting components.

Mounting in mechanical assemblies

The high hardness (Shore D 84) supports secure connections under vibration and load, while the low outgassing ensures long-lasting adhesion. The shear strength of 6 kN/m enables robust adhesive joints.
