About Senda Glue: Dual-Base Manufacturing & R&D
Senda Glue manufactures water-based and hot-melt adhesives plus aqueous barrier and heat-seal programs for packaging, paper converting, and specialty assembly—backed by batch documentation and application engineering.
From Dongguan Roots to Dual-Base Supply
Growth measured by capacity, export programs, and chemistry that matches how converters actually run their lines—not marketing slogans.
Founded in Dongguan
Started in the Pearl River Delta with formulation focus on packaging and assembly adhesives for regional converters.
Second Base in Wenzhou
Added Wenzhou production to increase capacity, shorten lead times, and add supply redundancy for export customers.
Export Programs Scale Up
ISO 9001 quality system and grade-scoped compliance documentation supported expansion into Europe and North America.
Barrier & Repulpable Coating Lines
Aqueous barrier and heat-seal programs run parallel to adhesive hubs—each qualified per pack structure, not one universal “sustainable” label.
Dual-Base Production & Logistics
Wenzhou and Dongguan facilities share process controls and QC release—redundant capacity for large programs and faster regional dispatch.
Reaction & Blending
Stainless kettles and in-line viscosity checks keep batch consistency visible from lab screen through bulk dispatch.
R&D & Application Lab
Substrate screening, open-time tuning, and coating holdout tests before your line trial—not after.
Warehouse & Dispatch
Climate-controlled storage and export paperwork (TDS, SDS, CoA) prepared for the grade you nominate.
ISO 9001 Quality System
Documented incoming inspection, in-process checks, and release testing—environmental management aligned where programs require ISO 14001.
50,000+ Tons Annual Capacity
Combined throughput across Wenzhou and Dongguan for high-volume packaging and converting programs.
Climate-Controlled Storage
Raw materials and finished goods held at specified temperatures to protect shelf life before your line consumes the batch.
How We Qualify Programs
Trust comes from repeatable batches and paperwork that matches your pack structure—not blanket “approved” badges on a homepage.
Incoming Material Lot Records
Incoming resin and additive lots logged against batch records before they enter production.
Application Engineering
Chemists and field engineers tune viscosity, solids, and open time on your equipment—not only in a beaker.
QC Release by Batch
Viscosity, solids, and bond tests against internal specs before drums or IBCs ship.
Documentation by Grade
TDS, SDS, and compliance statements scoped to the grade and market you declare—175.105 / 176.170 routes where applicable, REACH/RoHS on request.
The People Behind the Performance
Chemists, operations leaders, and application engineers who stay involved from lab screen through line qualification.
Leo Zhang
Chief Executive Officer (CEO)
Founder leading product portfolio direction across adhesives and aqueous coating programs.
William Wang
Chief Operations Officer (COO)
Oversees dual-factory production planning, inventory, and export dispatch stability.
Don Yeh
Senior Application Engineer
Eight years integrating adhesives on folder-gluers, straw lines, and coating stations—troubleshooting viscosity and bond failures in the field.
Principles We Operate By
Decisions on the plant floor and in the lab—not taglines for a brochure.
Line-Matched Chemistry
Formulations qualified on your substrates and speeds, with changes documented when we tune a grade.
Batch Integrity
Traceable lots and release data so QA can tie a drum back to production records.
Responsible Product Development
Repulpable and bio-based routes where structures support them—pilot scale first, claims tied to test data.
What Converters Tell Us
Feedback from packaging and converting partners after qualification—not generic marketing quotes.
"Senda kept batch viscosity stable through our folder-gluer season and routed us to the right food-contact documentation for the carton program."
Production Director
EU folding-carton converter
"Their team answered audit questions with grade-specific TDS packs instead of a one-size generic compliance sheet."
