Protection for delicate electronics. Dow DOWSIL Q3-6575 Dielectric Gel Clear is a two-component, heat-curing, low-temperature silicone gel used for protecting and sealing electronic devices from high voltages, moisture, and mechanical and thermal shock. It uses a 1:1 mix ratio by weight or volume. This kit is a Dow product repackaged by KitPackers, an authorized repackager of Dow.
Gel characteristics. As a dielectric gel, Q3-6575 cures to an extremely soft material that cushions and protects delicate components. Gels retain much of the stress relief and self-healing character of a liquid while providing the dimensional stability of an elastomer, and their naturally tacky surface can adhere to many substrates without a primer.
Where it is used. Its soft, resilient nature suits potting and sealing of sensitive circuits, isolating them from moisture and contaminants and providing high-voltage insulation. The self-healing quality lets the gel reflow and reseal around probes or leads, which is valuable in serviceable or test-point assemblies.
Handling notes. The 1:1 mix ratio simplifies proportioning, and the material heat cures. Because it is repackaged by KitPackers, the underlying material is the genuine Dow product. Review the product and Safety Data Sheets and confirm the cure schedule for your application before production.

FAQs
What is DOWSIL Q3-6575 used for?
It is a two-part silicone dielectric gel used to protect and seal electronic devices from high voltages, moisture, and mechanical and thermal shock. Curing to an extremely soft material, it cushions delicate components while providing electrical insulation, making it well suited to sensitive circuits and assemblies.
How is Q3-6575 mixed and cured?
It uses a straightforward 1:1 mix ratio by weight or volume and is heat-curing, with low-temperature capability. The simple ratio eases proportioning, while heat cure gives controlled processing. Consult the technical data sheet for the recommended cure schedule at your chosen temperature before production use.
Why choose a soft dielectric gel?
Gels cure extremely soft and keep much of the stress relief and self-healing character of a liquid while offering an elastomer's dimensional stability. That protects delicate components from thermal and mechanical stress and lets the gel reflow and reseal around leads in serviceable, test-point, or repairable assemblies.
Does the gel need a primer to adhere?
Dielectric gels of this type typically cure with a naturally tacky surface that adheres to many common substrates without a separate primer. For demanding or low-energy surfaces, confirm adhesion for your specific materials, and review the technical data sheet and Safety Data Sheet before committing to production.
What does 'repackaged by KitPackers' mean?
This kit contains genuine Dow Q3-6575 dielectric gel repackaged into this size by KitPackers, an authorized Dow repackager. The underlying material and its documented properties are the Dow product; KitPackers simply provides a convenient container format rather than altering the formulation.
