What are instant adhesives

Instant adhesives are cyanoacrylates; as you’ve probably guessed, they bond and cure very fast. Cyanoacrylates were originally discovered in 1942 and were used to create clear plastic gun sights. Today, they are used in virtually every industry from automotive and manufacturing to the surgical room adhering tissue together.

Cyanoacrylates are acrylic monomers that transform into a strong polymer resin when cured. Unlike most adhesives, cyanoacrylates instantly cure in the presence of moisture. The smallest amount of humidity in the air will create a bond between 5 and 90 seconds, depending on the cyanoacrylate used.

Most common types of cyanoacrlates

ECA – Ethyl Cyanoacrylate

Generally inexpensive to produce and highly versatile, ECA adhesives are used in various industries for their ease of application and fast cure time, providing a strong and instant adhesion. Unfortunately, ECA adhesives have a few disadvantages associated with their volatility. They create blooming, have an acrid odor, and are inflexible, resulting in cracks.

MECA- Methoxyethyl Cyanoacrylate

Very closely related to ECA, MECA-based adhesives were designed to overturn the disadvantages of ECA adhesives. This new version of cyanoacrylate has a much lower odor, significantly less bloom, and more flexibility resulting in less cracking. The disadvantage is primarily due to its production cost and producing low to moderate yields (40% – 45%).

The future of instant adhesives

After 70 years, cyanoacrylates are still produced using the Knoevenagel process. Despite the success of many leading brands, this process has limitations such as:

Time-consuming
Poor for the environment due to the solvent used
High energy consumption since very high temperatures are needed during production
Low yields for most monomers

Bostik’s engineers have discovered a way to overcome all the issues production faced in the past. Bostik’s engineering team created a new generation of adhesives that are faster to produce, consume less energy, require less heat, and are more environmentally friendly than their predecessors.

Here at BC Adhesives, we proudly carry Born2Bond — a crackles MECA-based instant adhesive with all the advantages of its predecessor and none of the disadvantages, producing less odor, increasing flexibility, and eliminating blooming, opening the doors to endless possibilities and industries.

Low odor
Peel resistant
Bonds to most materials, including polystyrene

Born2Bond Light Lock

Born2Bond™ Light Lock MV, HV, Gel and 30X are patented, low-odor, low-blooming, dual-curing (contact and light curing) cyanoacrylate adhesives. They are designed for bonding applications that require fast fixturing, coating or surface cure. The UV and visible-light cure sensitivity allow rapid bonding through transparent parts and quick curing of light-exposed bulk or surface-coated areas. Further, the product’s instant bonding capability ensures cure between opaque substrates (contact cure).

Features

Dual cure formulation: instant and photo-cure
Fixture time of 60 seconds without light exposure, and 5 seconds with light curing*
Can be cured with visible and UV-LED light
Long open time without activation
Dry to touch, tack free surface cure
Cure-on-demand of excess material released from bondlines
Bonds, fills, reconstructs and coats
Low odor, low blooming
Highly flexible and elastic

Born2Bond Flex

Born2Bond™ Flex is a patent-pending, flexible, elastic and low-odor instant adhesive with exceptional adhesion to a very broad range of materials and surfaces. It becomes a polymer (hardens) with more than 200% elongation with a working time (in mixer) of up to six minutes. It can be used for high-volumetric gap filling, achieving instant adhesion to most plastics, woods and metals as well as to porous and irregular surfaces.

Features

Fixture time in 60 seconds*
Hardens in 5-10 minutes*
Elongation > 200%
Absorbs impacts and vibrations
High peel strength
