Custom Clear 0 Hardness Soft Silicone Gel 1:1 Waterproof Potting Encapsulant for Pressure Sensor Junction Box PCB

HANAST HN-6607 Clear 0 Hardness Soft Electronic Silicone Gel

HN-6607 A/B is a transparent, ultra soft (0 hardness / Shore 00) two component silicone gel with a self adhesive surface after cure. It combines low viscosity easy flow with excellent dielectric insulation, making it ideal for stress free potting of pressure sensors, junction boxes and PCBs where signal sensitivity and repairability matter.

Key Features

• Clear, fully transparent 0 hardness soft gel for visual inspection of sealed components
• Self adhesive, primerless bonding to most substrates after cure
• Repairable and reworkable, capable of repeated operation with very low shrinkage
• Low viscosity 300-500 mPa·s, easy flow, no solid fillers
• Excellent dielectric insulation 2.8-3.2 kV/mm and wide temperature range -60°C to 200°C
• Dust proof, moisture proof, shockproof and insulating performance
• Room temperature cure or 60-80°C accelerated cure, 1:1 mix ratio by weight
• Long operation time 120-180 minutes at 25°C for volume production
• Non-toxic, non-corrosive, solvent free and halogen free
• RoHS and REACH compliant for EU export

Typical Applications

• Pressure sensor, accelerometer and precision sensor potting with retained sensitivity
• Junction box and PCB waterproofing, dustproofing and conformal protection

FAQ

Q1: What is this clear 0 hardness silicone gel used for?
A1: It is used for pressure sensor, junction box and PCB potting, plus ECU, BMS, IGBT, EV battery and LED protection requiring soft stress free encapsulation.

Q2: Does it require a primer for adhesion?
A2: No. After cure the surface becomes naturally self adhesive and bonds to most substrates without a primer.

Q3: Can the gel be removed or reworked?
A3: Yes, it is a repairable and reworkable gel that allows repeated operation and easy removal with very low shrinkage.

Q4: What is the mix ratio and curing schedule?
A4: Mix Component A and B in a 1:1 ratio by weight. It cures at room temperature with a 120-180 minute pot life, or can be accelerated at 60-80°C.

Q5: Is it RoHS and REACH compliant, and what is the temperature range?
A5: Yes, HN-6607 is RoHS and REACH compliant, halogen free, and performs from -60°C to 200°C with 2.8-3.2 kV/mm dielectric strength.
