LOCTITE Universal Structural bonders are the next generation of universal bonders powered by patented hybrid technology. Historically, we have had a choice between cyanoacrylates (or instant adhesives) and structural bonders. Cyanoacrylates lend themselves to easy use as a 1-component product that cures fast and has high adhesion to plastics. Structurals on the other hand are generally 2-component or 2-step systems that require mixing but can fill large gaps and provide high performance environmental properties and durability.
The hybrid technology adhesives are versatile structural bonders that combine the strength of a structural adhesive with the speed of an instant adhesive for unlimited applications, giving you the freedom to design and build.

2-component hybrid adhesives cures by mixing of parts A (cyanoacrylate) and B (epoxy) when dispensed through a static mixer. Handling strength is achieved rapidly; full strength is achieved over time. Cure time will depend on the substrate (faster on steel vs polycarbonate and aluminium), bond gap (lower the bond gap higher the cure speed) and temperature (higher the temperature higher the cure speed).
General applications: assemblies involving mixed substrates – especially moulded plastic or poorly fitted parts subject to impact loading
Electrical machinery, optical goods, lighting, and loudspeakers – Magnet bonding, frame bonding, cover bonding
Durable consumer goods – bonding and sealing of enclosure, sub components, displays of power tools, home automation devices
Stiffener bonding, panel bonding in elevators, furniture, storage racks etc.
Sports goods like golf clubs, hockey sticks, rackets etc.

Epoxies: LOCTITE Structural adhesives based on epoxy technology bond multiple substrates providing high shear strength.
LOCTITE Structural adhesives based on acrylic technology bond multiple substrates and provide a rigid to slightly flexible bond.
LOCTITE Structural adhesives based on polyurethane technology are tough and durable as they have a blend of cohesive strength and flexibility.
LOCTITE Structural adhesives based on silane-modified polymer technology are designed for elastic seam and joint sealing and bonding of most metals and plastics.

LOCTITE structural adhesives have been proven to be able to take almost as much load as overlap welding and that too at only half the cost. LOCTITE adhesive also offer other advantages like making the process simple, and providing sealing along with bonding.
While double sided adhesive tapes are not messy, their application process is definitely very long and complicated – what with the need to cut to specific dimensions and expensive activators. LOCTITE adhesives are mostly applied through static mixers that ensures precise application without any mess.
There are many suitable LOCTITE structural adhesives based on acrylic, epoxy, modified silane and hybrid technologies that would be ideal for bonding polypropylene. Drop a query to our LOCTITE experts with the specifics of the application requirement and they will be able to recommend the right solution.
Rivets offer the advantage of instant assembly, however result into concerns of reliability because of uneven stress concentrate points that become fatigue and failure points and also lead to corrosion. Instead, LOCTITE structural adhesives offer better reliability and come in various cure types which can be further accelerated with the help of activators.
Yes, LOCTITE structural adhesives have been designed to withstand heavy loads under various ambient conditions. Especially, LOCTITE structural adhesives based on modified silane technology which cure in the presence of humidity, are excellent for outside applications where high temperature, UV resistance etc. features are preferred.
LOCTITE structural adhesives based on acrylic, epoxy, modified silane technology and hybrids are excellent for bonding rubber to metal. Drop a query to our LOCTITE experts with the specifics of the application requirement and they will be able to recommend the right solution.
Yes, bonding dissimilar substrates like glass to metal or even glass to glass is possible with LOCTITE adhesives. If optical clarity and aesthetics is a must, choose clear epoxies like LOCTITE E-30 CL. Otherwise LOCTITE acrylics are also a great choice for bonding glass to metal or glass to glass. Prefer modified silanes if glass has to be fixed to a metallic frame. Drop a query to our LOCTITE experts with the specifics of the application requirement and they will be able to recommend the right solution.
Removal of dirt, dust or other surface impurities from the surfaces to be bonded is important before adhesive application as they can interfere with the effectiveness of the bond strength. This can be achieved through either degreasing or abrasion. Chemical treatments like primers, corona discharge, flame and plasma treatments can also be used to modify the surface properties to further enhance bond strength.
Open time is the time within which parts should be assembled post application of the adhesive to ensure proper surface wetting and achieve maximum strength.
This term is relevant for adhesives where activator is used on one of the parts. On-part life is the time within which activator or primer provides full performance.
Fixture time of an adhesive is the time needed to achieve enough strength to hold the parts together without additional support or to achieve lap shear strength of 0.1 N/mm2 whereas full cure time of an adhesive is the time needed to achieve full performance.
Combination of two different adhesive technologies, which are normally stand-alone technologies and at the outset cannot be manually mixed. A Hybrid combines the positive attributes of both technologies which provides new performance parameter. LOCTITE Hybrid adhesives combine the speed of cyanoacrylates (commonly known as instant adhesives) with the strength of epoxies/acrylates to give universal that can bond anything in seconds providing high strength.
