High Flow Liquid Silicone for HEPA Filters Sealant

HONG YE SILICONE liquid tank sealant, also known as jelly silicone gel, is 1:1 two-part addition curing silicone for air filter encapsulation. This RTV silicone gel delivers zero oil bleeding, wide temperature resistance and great adhesion to metal & plastic. As core electronic potting compound, it serves high-temp filters, LCD workshops and precision components, with customizable colors and room/heat dual curing modes for global industrial buyers.

 

Our liquid tank silicone (jelly silicone gel) is dual-component RTV 2 silicone rubber, consisting of transparent Part A and customizable colored Part B. As professional filter potting silicone, it works alongside our pad printing silicone and medical grade body silicone in our full silicone raw materials lineup. Eco-friendly, flexible and stable, it acts as sealing & shock buffer for liquid tank HEPA filters, electronic modules and high-temperature industrial equipment, solving air leakage and moisture corrosion troubles for manufacturers worldwide.

 

Low viscosity liquid mold silicone for smooth, bubble-free pouring after vacuum defoaming

Dual curing options: room-temperature vulcanization or fast heat curing

Strong adhesion on aluminum, stainless steel, ABS, PC and various metal panels

Non-oozing after full cure, no harmful byproducts during crosslinking

Superior weather resistance, anti-corrosion, flexible to absorb thermal expansion stress without cracking

 

Thoroughly stir Part A and Part B separately before mixing

Blend two components strictly at 1:1 weight proportion

Vacuum defoam mixed compound under 0.08MPa for 3 minutes

Pour mixture into filter aluminum tanks; cure naturally for 3–8 hours or heat at 80–100°C for 20 mins to shorten cycle

 

Liquid tank HEPA air filters & high-efficiency air outlets

Optical electronics, LCD production lines and precision electronic components

High-temperature ovens, industrial air filters and induction cookers

Electronic power module encapsulation, insulation and moisture-proof protection

This silicone potting compound cuts your filter reject rate, extends equipment service life and reduces post-maintenance costs for mass assembly factories.

 

All liquid tank jelly silicone complies with ISO9001, CE and RoHS standards. Every batch passes strict internal QC inspection before delivery to meet global industrial safety norms.

 

Custom color matching for Part B; adjustable viscosity and curing speed to match your automated assembly line requirements. OEM bulk packaging service is available for long-term cooperative manufacturers.

 

We own 20 professional silicone production lines with standardized raw material testing. All silicone raw materials are inspected before production; finished jelly silicone gel undergoes curing performance and adhesion testing to guarantee consistent batch quality.

 

Q1: Will the silicone fail to cure after storage?

A: Slight layer separation is normal after long storage; full stirring restores original performance. Avoid contacting tin, amine and sulfur substances to prevent curing failure.

Q2: What packaging specifications are available?

A: 20kg and 200kg drums for both Part A and Part B, classified as non-dangerous goods for global shipping.

Q3: What is the shelf life of unopened glue?

A: 1 year under sealed, acid-free and alkali-free storage environment.

Q4: Can it be used together with your other silicone products?

A: Yes, we supply matched mold making silicone, pad printing silicone and electronic potting compound as one-stop silicone raw material solutions.
