Permabond PT003260050C0101 - PT326 Polyurethane Adhesive 50ml 2-Part (Case of 25)
Permabond PT326 — 2-Part Polyurethane Adhesive | 50ml Dual Cartridge | Case of 25
Permabond® PT326 is a room-temperature-curing 2-part polyurethane structural adhesive engineered for high-strength, flexible bonding of metals, plastics, composites, and dissimilar substrates. Supplied in 50ml dual cartridges with static mixers included, PT326 delivers controlled mixing and consistent bond quality with no heat or special curing equipment required. Its flexible bond line absorbs stress, vibration, and thermal cycling — making it well-suited for automotive, marine, industrial equipment, and transportation assembly applications. Sold in cases of 25 cartridges.
Case of 25 × 50ml dual cartridges. Static mixer nozzles included. For industrial use only.

Key Features
- Room temperature cure — no ovens, heat lamps, or UV equipment required; simplifies production and allows bonding of heat-sensitive substrates
- Flexible bond line — absorbs stress, vibration, and thermal expansion/contraction; maintains bond integrity in dynamic and high-vibration assemblies
- Wide substrate compatibility — bonds metals (aluminum, steel, stainless), plastics (ABS, PVC, PC, acrylic, FRP), composites, wood, ceramics, and glass
- Excellent chemical and environmental resistance — withstands exposure to oils, fuels, hydraulic fluids, solvents, moisture, and temperature cycling
- Static mixer included — each cartridge ships with a static mixer nozzle for automatic 1:1 mixing at the point of dispensing; ensures consistent mix ratio and bond quality
- Gap filling capability — fills surface irregularities and gaps; suitable for bonding parts with rough, uneven, or slightly mismatched mating surfaces
Industries & Applications
- Automotive manufacturing — structural panel bonding, trim attachment, underbody component assembly, and repair of plastic and composite parts
- Marine and RV manufacturing — hull bonding, deck panel assembly, and structural laminate joining where flexibility and moisture resistance are critical
- Industrial equipment assembly — metal-to-metal and metal-to-plastic structural bonding in machinery, enclosures, and fabricated components
- Transportation vehicle assembly — bus, rail, and specialty vehicle body panel bonding and composite structure assembly
- Construction and building materials — composite panel, cladding, and structural component bonding
- Appliance manufacturing — plastic housing assembly, metal-to-plastic joins, and vibration-resistant component attachment

Frequently Asked Questions
What is the difference between the Permabond PT326 and PT321?
Both PT326 and PT321 are 2-part polyurethane adhesives from Permabond, but they have different performance profiles. PT321 is optimized for high initial strength and faster handling time, making it suitable for production environments where quick fixture is important. PT326 is formulated for a more flexible, impact-resistant bond line with excellent chemical resistance — ideal for applications subject to vibration, thermal cycling, and environmental exposure.
Does PT326 require heat to cure?
No — PT326 cures at room temperature with no heat, UV, or special equipment required. This eliminates the need for ovens or heat lamps and allows bonding of heat-sensitive substrates like certain plastics and composites. Elevated temperature can accelerate cure speed if needed, but is not required for full bond development.
What dispensing equipment is compatible with the 50ml cartridge?
PT326 50ml dual cartridges are compatible with standard 50ml dual-cartridge dispensing guns (manual or pneumatic). The static mixer nozzle included with each cartridge automatically mixes the 1:1 A:B ratio as material is dispensed — no separate mixing step is needed. Replacement static mixers are available separately.
What substrates does PT326 bond, and does surface preparation matter?
PT326 bonds a wide range of substrates including aluminum, steel, stainless steel, ABS, PVC, polycarbonate, acrylic, FRP, carbon fiber composites, wood, ceramics, and glass. Surface preparation is critical for maximum bond strength: surfaces should be clean, dry, and free of oils, release agents, and loose particles. For metals, light abrasion and solvent wipe (IPA or acetone) is recommended. For low-energy plastics, a surface primer or plasma treatment may improve adhesion.
How many cartridges are in a case and are static mixers included?
Each case contains 25 × 50ml dual cartridges. Static mixer nozzles are included with each cartridge — one mixer per cartridge. Additional replacement mixers are available if a partially used cartridge needs to be re-sealed and reused at a later time.
