MDSI 6125 Transparent Silicone potting compound
- Two components, condensation dealcoholization type
- Low viscosity, easy to process, strong operability
- Low hardening shrinkage, no corrosion and no stress
- Excellent high temperature electrical insulation and stability
- Excellent adhesion, good water resistance, moisture resistance
MDSI 6125 A/B is suitable for potting protection of various components. It can be deeply cured, and the two components have good fluidity after mixing. The operation time can adjust the proportion of curing agent according to the temperature. There is no need to use other primer before use, which has a good bonding effect on most materials, and is suitable for the fixing of accessories and waterproof, dustproof and anti-leakage.

Operation and use process
- The A and B components are weighed according to the ratio of 100:10, mixed evenly, and injected directly into the components (or modules) that need to be potting and protection. It is best to slowly inject along one side of the device wall to reduce the generation of bubbles.
- The pot-sealed component is left to stand and let its own bubble, and the customer can vacuum debubble the mixed adhesive before potting. It is cured directly at room temperature, and the adhesive layer is usually elastic within 1-6hr.
- Please consult the Marketing Department of our company for filling and sealing equipment requiring quantitative gluing.
