Permabond TA4631 Polyolefin (PE, PP), Nylon & Rubber Bonder, Clear Color, Thin Viscosity 12-18 min Acrylic MMA Adhesive White

Description

PERMABOND TA4631 is a 2-part, 1:1 no odor acrylic adhesive. It has been developed to bond low surface energy plastics such as polypropylene and polyethylene with no primer or expensive surface treatment required. It can also be used to bond a wide variety of other materials such as metals and composite materials and is ideal for bonding dissimilar surfaces. This product is similar to TA4630 but does not contain micro beads making it suitable for joints with smaller gaps.

Popular for bonding:

Nylons, PE, HDPE, LDPE, UHMW, PP, PPCO, PPHO, COPP, HOPP, Natural Rubbers, Synthetic Rubbers

TA4631 is a part of a 4-formula Family:

Grade	Handling Strength	Set Time / Pot Life	Notes
TA4605	~25 minutes	5-10 minutes	Fast set, gel consistency, off-white, fast set
TA4610	~50 minutes	12-15 minutes	Longer pot life, gel consistency, off-white
TA4611	~35 minutes	10-15 minutes	Medium Pot Life, Thin Flowable, Low odor, clear
TA4631	~40 minutes	12-18 minutes	Longer Pot Life, Thin Flowable, Low odor, clear

TA4631 is also a substitute / backup formula for these formulas:

• 3M DP8005
• 3M DP8010
• Scigrip SG400 LSE

Features and Benefits

• No odor formula
• Lower viscosity / flowable formula

ApplicationInstructions

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.

Note:This product willNOTset in temperatures below 50F (10C) Make sure to keep the material warm throughout the curing process.
