Application Cases by Scenario

1. New Energy Vehicle Battery Pack Sealing

SIENOX equipment realizes linked control of viscosity and defoaming for silicone structural adhesives. High-speed mixing is completed within 10 minutes at 60℃, with adhesive porosity below 0.2% to meet IP67 waterproof standard, supporting zero leakage for the customer’s annual output of 500,000 battery packs.  

2. Aerospace Composite Bonding

For adhesives used in carbon fiber-epoxy prepreg bonding, the customized dual-station SIENOX system disperses nano-ceramic fillers under 5Pa vacuum, lifting the temperature resistance of adhesive layers beyond 300℃ for composite wing manufacturing of domestic large aircraft.  

3. Building Curtain Wall Structural Assembly

With the SIENOX modular production line, customers achieve fully enclosed production of MS polymer adhesives from raw material feeding to automatic filling. VOC emissions are cut by 90% and curing speed increased by 40%, meeting green building certification requirements.
