Full specification details of drum packaged PU sealant (large packaging)
20kg iron drum PU adhesive
Large barrel two-component PU adhesive
1、 Mainstream barrel packaging specifications (industrial large packaging single/two-component)
- Single component PU (moisture curing, ready to use upon opening, preferred for automotive sheet metal/wind power/construction machinery assembly lines)
Small ton bucket: 20kg/iron bucket (most commonly used): Batch gluing for vehicle manufacturers and small and medium-sized projects, equipped with a laminating machine
Large iron drum: 230-240kg/closed iron drum (55 gallon standard drum): Large automobile enterprises, sealant OEM, automated production line centralized procurement, main specifications for bulk shipments in foreign trade
Color: black/white/gray, thixotropic type (no flow on the facade), self leveling (2 types of road surface grouting) subdivision - Two component AB type PU (A main agent+B curing agent, mixed curing, bridge/tunnel/hydraulic expansion joint)
National standard configuration: 25kg/set drum (A: B ≈ 10:1 pre packaged), one drum contains 22.7kg of A glue+2.3kg of B curing agent, can be opened and mixed for construction
Large drum: 200kg set of iron drums (divided into A/B drums), centralized procurement for large-scale infrastructure projects
2、 Product segmentation&applicable scenarios
Automotive sheet metal PU sealant (20kg/240kg drum)
Paintable, grindable, vibration resistant, low temperature resistant -40 ℃, sealing of sheet metal welds on truck carriages, bus bodies, and construction machinery, replacing mounting adhesive, with a 30% reduction in assembly line costs+
Building low/high modulus PU (20/230kg)
Low modulus: concrete expansion joints, roof waterproofing; High modulus: pressure resistant sealing for pipelines and equipment, according to the national standard JC/T482-2022
Self leveling road PU sealant (20/230kg)
Liquid self leveling, no need to scrape, pouring cracks into high-speed and airport runways
Special PU for rail transit (20kg drum)
High speed railway carriages and subway box bodies are bonded and sealed, weather resistant, non yellowing, and silicone free
3、 Key points of storage, transportation and construction
Storage: Store in a cool and shaded warehouse at 5-25 ℃, with a shelf life of 9 months for single component and 12 months for two-component. Do not expose to direct sunlight or moisture (moisture can cause premature solidification in single component barrels)
Construction equipment: 20kg pneumatic adhesive press; 240kg large barrel with vertical barrel pressure pump and automated glue supply system
Foreign trade shipment: 240kg iron drum full container sea freight, approximately 80 barrels per 20 foot container; 20kg drum pallet packaging for export
4、 Advantages of comparing small packages (310ml/600ml pack)
The unit price of large barrels is 25% to 40% lower, suitable for mass production factories, large-scale projects, and foreign trade wholesale; The support is only used for scattered maintenance.
