LOCTITE Structural adhesives based on acrylic technology bond multiple substrates, including metals, ferrites, glass, plastic (polypropylene, polyethylene), and wood. This helps in achieving strong and durable bonds, high impact, and peel strength. They are 2-component no mix (also known as 2-step) systems or 2- component pre-mix systems. The 2-component no mix systems have flexible assembly times whereas the 2- component premix systems have higher gap tolerances.
2-component no mix product-Adhesive is applied on one side and the activator (initiator) on the other (generally the inactive substrate). The curing starts immediately after joining the two substrates. These are recommended for:
2-component premix product-The 2 parts of the dual cartridge are mixed in a static mixer mounted on the cartridge. These adhesives are formulated with methylmethaacrylate (MMA) resin to form high strength bonds. These are recommended where:
Bonding metal panels on metal frames such as cabinets, antennas etc.
Bonding metal to metal where riveting or welding does not work
Magnet bonding in speakers, electric motors, transformers, small engines
Bonding plastic to plastic like ABS to polycarbonate
Bonding metals to plastics like cast iron to ABS or cast iron to glass reinforced plastic
Bonding composite wall panels to steel frame in vehicles for lightweighting

Epoxies: LOCTITE Structural adhesives based on epoxy technology bond multiple substrates providing high shear strength.
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 based on hybrid technology combine the strength of epoxies with the speed of cyanoacrylates. These universal bonders ensure substrate versatility, cure faster and have high strength.

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.
