Bluesil RTV 8352 LV A & B is a medium-hard 2K-Pt silicone potting compound (Shore A 55, whitish) with a 1:1 mixing ratio for electrotechnical coatings and encapsulation applications.
This product range comprises 2K polyaddition silicone elastomers for universal electrotechnical encapsulation and coating — low viscosity, with good dielectric properties. RTV 8352 LV is tailored to specific industrial applications — the most important properties and areas of application are listed below.
Bluesil RTV 8352 LV uses a 1:1 mixing ratio (instead of 10:1) — insensitive to dosing deviations and ideal for 2K mixing machines. Its low viscosity (2,200 mPa·s) allows for easy refilling of reservoirs.

Frequently asked questions about RTV 8352 LV
Practical questions regarding processing and design — answered by SILITECH.
Bluesil RTV 8352 LV A & B: Medium-hard 2-component platinum silicone potting compound (Shore A 55, whitish) with a 1:1 mixing ratio for electrotechnical coatings and encapsulation applications. Main applications include electrical engineering encapsulation, electronic coating, and heat dissipation.
Polyaddition crosslinking is a two-component silicone chemistry using a platinum catalyst. Component A contains the platinum complex, and component B contains the SiH crosslinker. When mixed, the components crosslink without releasing reaction byproducts—no shrinkage due to outgassing, excellent dimensional accuracy, and low linear shrinkage. Important: Polyaddition silicones are inhibited by various substances—sulfur-vulcanized natural rubbers, tin-catalyzed RTV silicones, amine-catalyzed epoxy resins, and tin-stabilized PVC. In case of doubt, a preliminary test should be carried out.
Thoroughly stir components A and B before each processing step. Measure precisely according to the mixing ratio specified in the TDS (see comparison table above) – ideally by weight. Mix with an electric or pneumatic agitator at low speed (minimize air entrainment). Degas the mixture under vacuum (30–50 mbar) – the material will expand 3–4 times its original volume, bubbles will escape, and the material will settle back after 5–10 minutes. Then slowly pour into the mold from the lowest point to avoid air entrapment. For polyaddition systems, avoid contact with inhibitors (sulfur-based rubber, tin-based RTV, amine epoxides, PVC with tin salts).
Store in the unopened original container in a dry, cool place — typically between +5 and +30 °C, see TDS for exact values. Store components A and B separately; seal airtight after opening. Polyaddition systems are insensitive to moisture, but should be stored in a cool place to maintain pot life. Consult the Safety Data Sheet (SDS) before use.
