The two-component gel is mixed in a 1:1 weight ratio (A:B), has a low viscosity of 1000 mPa·s for excellent flowability, and achieves a density of 0.97 g\/cm³ after curing. Its softness is expressed in penetration (300 1\/10 mm) instead of Shore hardness, which is characteristic of a true silicone gel. With a pot life of approximately 150 minutes at 23 °C and a cure time of 8 hours at 23 °C or 15 minutes at 100 °C, the gel offers ample processing time combined with rapid heat curing. The combination of extremely low modulus, high dielectric strength, and excellent chemical purity makes this gel ideal for protecting sensitive electronics against vibration, moisture, and thermomechanical stress.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePenetration 300 1\/10 mm\u003c\/strong\u003e – very soft gel with extremely low modulus that absorbs thermomechanical stress without transferring it to sensitive components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDielectric strength \u0026gt; 23 kV\/mm\u003c\/strong\u003e – reliable electrical insulation that prevents leakage currents and breakdown in power modules\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume resistivity 10¹⁵ Ohm·cm\u003c\/strong\u003e – excellent insulation resistance that remains stable over a wide temperature range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity 0.97 g\/cm³\u003c\/strong\u003e – lightweight, low-stress encapsulation with good flowability for complete filling of complex geometries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePot life 150 minutes at 23 °C\u003c\/strong\u003e – ample processing time with the option of rapid heat curing in 15 minutes at 100 °C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame retardant UL 94 HB\u003c\/strong\u003e – meets the UL 94 HB flammability rating for use in electronic enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEncapsulation of electronic components for the automotive and power electronics industries (ECU and PCU)\u003c\/li\u003e\n\u003cli\u003eSelective potting and dam-and-fill protection of PCBs and power modules\u003c\/li\u003e\n\u003cli\u003eEncapsulation of solar cells and photovoltaic assemblies\u003c\/li\u003e\n\u003cli\u003eProduction of vibration-damping elements\u003c\/li\u003e\n\u003cli\u003eSealing of cleanroom filters\u003c\/li\u003e\n\u003cli\u003eProtection of sensors and control units in heating, ventilation, and air conditioning (HVAC)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eProcessing Instructions\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eFirst, stir component A and component B thoroughly and separately.\u003c\/li\u003e\n\u003cli\u003eMix component A and B in a 1:1 weight or volume ratio.

Curing can be inhibited by contact with sulfur-containing materials, plasticizers, urethanes, amine-containing substances, and organometallic compounds, especially organotin compounds (such as condensation silicones). Ensure that all surfaces are clean and free of these contaminants. If in doubt about a substrate, first perform a small-scale test to determine compatibility.\u003c\/div\u003e\u003ch3\u003eAbout the Manufacturer\u003c\/h3\u003e\u003cp\u003eWacker Chemie AG is a global market leader in the development and production of silicones for industrial and technical applications.\u003c\/p\u003e\u003ch3\u003eProfessional Support\u003c\/h3\u003e\u003cp\u003eDo you need advice on the right encapsulation or protection gel for your electronics application, on adjusting pot life with ELASTOSIL® Catalyst EP or Inhibitor PT 88, or on processing and curing?
