LOCTITE HY 4070
Product category: Structural adhesives
- Technical specifications
LOCTITE® HY 4070™ Universal Bonder is designed for the assembly of parts with bond gaps up to 0.2 in (5 mm), and/or for applications where the complete cure of excess adhesive is a must. The gel consistency prevents adhesive flow even on vertical surfaces. HY 4070 is ideally suited for applications where temperature and moisture resistance is required.
Best application results are achieved with use of the LOCTITE cyanoacrylate mixing nozzle (contained in the 11 gram kit).
Temperature resistance from -40 to +100°C
Gap filling up to 0.2 in (5 mm)
Gel consistency prevents adhesive flow, even on vertical surfaces.
Excellent bonding characteristics to a variety of substrates including plastics, rubbers, and metals

How to use
It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7070™) to degrease and clean surfaces prior to applying the adhesive.
Place plunger in the back of the cartridge. Remove cap from cartridge. Dispense a small amount so that material is coming out of both sides. Attach mix nozzle and dispense a bead at least half of the length of the nozzle. The material is ready to use.
Apply a bead of material to one of the surfaces to be bonded. Join the parts and fixture in a way to prevent movement of the part until handling strength is obtained.
A hybrid is a mix of two adhesive chemistries. For example, the LOCTITE HY 4070 product is a cyanoacrylate/methacrylate mix.
Yes, hybrids are two-part products. Bumping and purging ensures product is flowing from both sides and mix at the proper mix ratio.
LOCTITE® HY 4070 is available in a 11gram 10:1 plastic syringe, supplied with a plunger and 4 nozzles. Additional nozzles are available in bags of 5 (IDH 1434516). LOCTITE® HY 4070 is also available in a 45gram 10:1 dual cartridges. Mix nozzles and dispense gun are not included with this package size.
No, it is not recommended to use LOCTITE HY 4070 for bonding to glass.
Refrigerated storage is not required for this adhesive. Refer to the product TDS for recommended storage.
Metals: all mentioned adhesives are compatible with metal substrates but with varying performance characteristics depending on the technology selected. Plastics: all adhesives other than anaerobic adhesives which may cause stress-cracking in some sensitive polymers. Consult Henkel technical team for further guidance.
