Permabond TA4631 Clear Adhesive for HDPE, Polyethylene, Polypropylene, Teflon, Nylon, Low-Odor Clear Thin FLowable, 2-Part 1:1 Mix, No Primer Needed for Polyolefins, 12-18 Min Set Time

Permabond TA4631 is a versatile two-part acrylic adhesive engineered for exceptional bonding performance. This low-odor formula features a 1:1 mixing ratio and requires no primer or surface treatment, making it ideal for challenging materials like polyethylene PE, polypropylene PP, Nylon PA, Teflon PTFE and most plastics and metals. With a set time of 12-18 minutes and room temperature curing, this thin viscosity flowable adhesive delivers outstanding impact and shear strength. It excels in bonding dissimilar materials, including metals, plastics, composites, carbon fiber, and various rubber compounds. The formula is particularly effective on low surface energy plastics and provides excellent chemical resistance. Perfect for industrial applications, this adhesive creates strong, durable bonds across a wide range of substrates, from stainless steel and aluminum to specialized materials like PTFE, nylon, and various polyolefins. Unlike its counterpart TA4610, this version contains no microbeads, making it suitable for applications with minimal gap requirements. TA4631 is also a substitute / backup formula for these formulas: 3M DP8005, 3M DP8010, Scigrip SG400 LSE Application Instructions: 1. Surface Prep: Ensure surfaces are clean, dry, and grease-free. Use Isopropyl (rubbing alcohol) wipe if necessary. 2. Mixing & Dispensing: Use a static mixer to apply a thin, even bead of mixed adhesive. 3. Assembly & Clamping: Press parts firmly and maintain pressure until handling strength is achieved. 4. Curing Notes: Adhesive cures best inside joints (anaerobic). Adhesive exposed to air may remain tacky for an extended time (not a defect, just a characteristic, it will eventually lose it's tackness). Remove excess before curing. Avoiding Common Issues ■ Leaving large beads→ sticky residue. ■ One side exposed to air → tacky, sticky surface. or crystalization or crystal-like curing ■ Not clamping long enough → weak bond. ■ Stressing before full cure → joint failure. ■ Always allow full cure before loading. Troubleshooting: Still tacky? Exposed to air, not a bond failure, allow it to keep curing, can take a while to lose tackiness. Crystalization? Exposed to air, not a bond failure, allow it to keep curing, can take a while to lose tackiness. Slow to grab? Possibly TA4610 (longer cure) or surface contamination. Joint failed? Likely due to early stress or insufficient clamping.

• BONDS HARD-TO-GLUE SURFACES: Creates a strong bond to, HDPE, Teflon (PTFE), Nylon (PA), Carbon Fiber, ABS, Polypropylene PP, Polyethlyenes PE, Most Metals and is one of the very few products that can actually form a strong bond without flame treatment for these surfaces.
• IMPORTANT: This product will NOT set in temperatures below 50F (10C) Make sure to keep the material warm throughout the curing process.
• QUICK CURING: Sets in 12-18 minutes at room temperature with excellent impact and shear strength for durable bonds
• LOW ODOR FORMULA: Features a flowable, lower viscosity formula with minimal odor, making it ideal for indoor applications
• MATERIAL COMPATIBILITY: Bonds effectively to metals, composites, carbon fiber, FRP, GRP, ABS, polycarbonate, PVC, PTFE, various rubbers, and most polyolefins
• NO SURFACE PREPARATION: Eliminates the need for expensive surface treatments, flame-treating, or plasma treating before bonding, saving time and cost
