HONG YE SILICONE low-water-absorption moisture-blocking liquid tank sealant is professionally formulated for high-humidity factories, coastal workshops and damp filtration working conditions. It features ultra-low water absorption and strong moisture barrier performance. Effectively preventing damp penetration and mildew aging, it delivers stable long-term sealing for liquid tank filters in humid industrial environments.

Product Overview
HONG YE SILICONE damp-proof jelly silicone gel solves the common failure problem of ordinary sealants in long-term humid environments. Traditional potting silicone easily absorbs water vapor, causing swelling, mildew and sealing gap loosening. This upgraded hydrophobic formula maintains stable size and airtightness even in continuous high-humidity workshops and coastal humid climates.


Product Features
Ultra-low water absorption rate, resisting water vapor penetration and damp swelling. Excellent hydrophobic and mildew-proof performance, no mold growth in long-term damp environment. Flexible and non-deformable, retaining perfect fitting with filter frames. Stable insulation and sealing performance, avoiding leakage caused by moisture erosion.

Operation Steps
1. Stir HONG YE Part A and Part B fully and evenly;
2. Mix at standard 1:1 weight ratio;
3. Vacuum defoam for 3 minutes;
4. Cure completely at room temperature to form a dense moisture-proof sealing layer.
Application Scenarios
Ideal for liquid tank filters used in coastal factories, pharmaceutical workshops, food processing plants and other long-term high-humidity industrial purification scenarios.
Certifications and Compliance
HONG YE SILICONE complies with ISO9001, CE and RoHS standards, suitable for global high-humidity industrial equipment supporting.

Customization Options
Custom color and enhanced hydrophobic formula are available for ultra-damp working conditions.

Production & QC
Each batch passes strict water absorption and damp aging tests to ensure long-term moisture-proof stability.
