Instant adhesives fulfil a range of functions where one- or two-component, room-temperature curing is required within production lines or repair shops. Suitable for any industry, they perform equally well when applied manually as they do within instant adhesive dispensing equipment on automated lines, with custom tool designs available made to fit individual specifications.

Typically, they are used for high-performance bonding of materials in seconds, with products available for rubber, polystyrene, wood, metal and even the latest generation plastics. Finally, with a wide range of viscosities available, there is an instant adhesive suitable for any workflow—from conventional bonding to gap filling and sealing.

Henkel’s range of Instant adhesives provide the following benefits:

  • Flexible adhesion for substrates that move
  • High strength between bonded substrates
  • Large temperature resistance range
  • Weather and moisture resistance
  • Low odor and low bloom adhesion

Finding the right instant adhesive for your needs is highly important since each performs differently depending on the materials to be bonded and the conditions they are subject to. Additionally, each of our LOCTITE® products possesses a range of attributes that suit certain applications better than others. Deciding between a range of cure times and fixture times may be crucial to the successful bonding of substrates. However, regardless of your requirements, the Henkel team is on hand to offer advice and guidance on the best instant adhesive for your design, process, or industry.

Types of Instant Adhesives

Instant adhesives, otherwise known as cyanoacrylate adhesives, are available in a variety of formulations from Henkel, with each designed to fulfil either general or specific functions. Featuring fix times as low 5 seconds, temperature tolerances between -65°F and 200°F, and sheer strengths of up to 3,760 PSI, our range of instant adhesives is made for demanding applications and environments. Available in a range of viscosities, from liquid to gel, you can find the ideal instant adhesive quickly and easily using our Product Selector Guide, additionally, you can learn more about our CA adhesives and instant adhesive gels here.

Cyanoacrylate Adhesives (CA Adhesives)

The term CA adhesive applies to most instant glues as they are usually derived from ethyl and cyanoacrylate esters. These toughened acrylic adhesives consist of one-part, room temperature cured glues that are suitable for all types of materials with the exception of glass. Easy to use across a broad range of applications, the LOCTITE® range of products includes low odor/low bloom CAs, light cure/rapid cure CAs, impact resistant CAs, and dedicated rubber bonding CAs alongside general purpose solutions that bond well to most materials.

Two-Part Cyanoacrylate Adhesive

Innovative two-part cyanoacrylate adhesives bring a greater level of control to both manual and automated processes, allowing you to mix the adhesive for curing. Available in a range of viscosities to suit your specific application, the LOCTITE® range of two-part cyanoacrylate adhesives is ideal for gap gilling applications when bonding plastics, rubbers, wood, paper and metals. Additionally, high-precision dispensing tips provide even greater accuracy in application while fix times as low as 15 seconds prevent sagging.

Instant Adhesive Gel

Instant adhesive gels are high viscosity solutions that provide greater control over adhesion where sagging or dripping may be an issue—in particular, on vertical surfaces or within gap filling applications. Available in low odor/low bloom and toughened/impact resistant formulas, the LOCTITE® range of instant adhesive gels are suitable for most materials where the adhesive needs to maintain shape during curing and fixing.

Instant Bond Adhesives

Instant bond adhesives (flashcure) provide the fastest curing and fixing times of all CA adhesives. With fix times of less than five seconds, near-instant bonding can be achieved through UV curing in applications where light can penetrate, but also in dark areas through conventional CA moisture curing. Additionally, CA accelerators can be used with premium CAs, either pre- or post-application, to further decrease curing and fixing times. Instant bond adhesives are the ideal choice for any application where materials need to be bonding quickly without compromising on strength, impact resistance or flexibility.

Instant Adhesive Applications

There are many applications for instant adhesives, and they are used within almost all industries—from medical to automotive. This is because they can be adapted to a broad range of materials while still offering high-strength and flexibility under a range of conditions. For more information on the most common materials that are bonded using CA adhesives, read on:

Adhesives for Rubbing Bonding

Dedicated rubber bonding adhesives meet the many challenges associated with rubber to rubber bonding. Designed to bond nitrile, butyl, polyurethane, silicone, EPDM, and natural rubbers quickly and securely, rubber bonding adhesives deliver fast curing times alongside flexibility once fixed to prevent cracking or splitting. They are also highly durable across a range of applications, making them ideal for general maintenance and repair.

Adhesives for Plastic Bonding

Suitable for a broad range of plastics, including hard-to-bond surfaces such as polypropylene and polyethylene, instant adhesives for plastics provide fast, strong, and flexible joining solutions in many industries. Including gap filling formulas alongside two-part plastic adhesives, the range of plastic bonding solutions is designed to meet the demands of manufacturers reliance on plastic components.

Adhesives for Metal Bonding

Instant adhesives for metals are ideal for joining or repairing mechanical parts, components, small appliances, and many other metallic items. Fast curing times are critical within metal bonding applications, and weather and moisture resistance in demanding environments is also important for manufactures that require durable bonding. Instant adhesives for metals also do not require clamping in order to join materials, ensuring fast bonding with minimal fuss.
