Super Glue: A Comprehensive Guide to Bob Smith Industries Adhesives

Super Glue, chemically known as cyanoacrylate (CA) adhesive, is a fast-bonding, strong adhesive that cures rapidly upon contact with moisture. It’s renowned for its ability to create powerful bonds across a wide variety of materials. Bob Smith Industries (BSI) has been a pioneering force in the adhesive industry, particularly within hobby and industrial sectors, developing a full line of specialized CA glues designed to meet diverse and demanding bonding requirements.

BSI’s journey began in the early 1970s, rooted in the competitive world of RC model aviation, where the need for reliable, high-performance adhesives was paramount. This foundation has driven BSI to produce adhesives that match or surpass the performance of larger corporations, earning them a reputation for quality and innovation. Their commitment ensures that whether you’re working on intricate models or robust repairs, there’s a Bob Smith Super Glue formulation engineered for the job.

Classifying Bob Smith Super Glues

Bob Smith Industries offers a meticulously categorized range of Super Glues, each formulated with specific viscosities and properties to excel in different applications. Understanding these classifications is crucial for selecting the optimal adhesive for your project.

Based on Viscosity and Gap-Filling Capability

The most common way to categorize BSI’s CA glues is by their thickness, which dictates their flow and gap-filling abilities.

• Insta-Cure (Thin CA): This is BSI’s water-thin formulation, designed for applications where the glue needs to penetrate tight-fitting joints via capillary action. It wicks deep into seams, curing in a matter of seconds to create a strong, invisible bond. It’s ideal for pre-fitted parts where minimal adhesive is required and speed is essential.
• Insta-Cure+ (Medium/Gap-Filling CA): A higher viscosity CA, Insta-Cure+ is the go-to for situations involving loose-fitting joints or small gaps that need to be bridged. While it sets quickly, often within five seconds, it offers enough working time for minor adjustments. This versatile glue is suitable for a broad range of materials and is a favorite among model builders and general repair enthusiasts. Full-strength curing can take up to three hours.
• Maxi-Cure (Extra Thick CA): As its name suggests, Maxi-Cure is BSI’s thickest CA adhesive. It’s specifically formulated to fill larger gaps and is particularly effective for bonding most plastics. Its slower setting time compared to thinner CAs provides extended working time, which is beneficial for complex assemblies or when positioning larger components.

Based on Special Properties

Beyond viscosity, BSI also offers specialized CA glues with unique properties to tackle specific material challenges or environmental concerns.

• Super-Gold (Odorless and Foam-Safe CA): Available in both thin and gap-filling medium thicknesses, Super-Gold is a revolutionary formulation that is odorless, non-frosting, and safe for use on foam. Unlike traditional CAs that emit irritating fumes and can “frost” clear plastics or dissolve foam, Super-Gold produces no fumes and maintains clarity. It bonds in just a few seconds longer than Insta-Cure and Insta-Cure+, making it ideal for attaching clear canopies in plastic model kits and bonding wood to white foam.
• Instaflex (Flexible CA): Instaflex is a unique offering that cures into a clear, flexible bond that doesn’t become brittle over time. This flexibility makes it perfect for applications where the bond needs to withstand movement, vibration, or stress without cracking. It’s particularly noted for its excellent performance on anodized aluminum and other materials that require a resilient, non-rigid adhesive.
• Insta-Set (CA Accelerator): While not a glue itself, Insta-Set is an essential companion product for BSI’s CA adhesives. It’s a solvent-based accelerator that rapidly cures all BSI Super Glues, often in under 10 seconds. This is invaluable for speeding up assembly, fixing parts in place instantly, or when working in low-humidity conditions where CA glues cure slower.

Comparing Bob Smith Super Glues

Choosing the right Bob Smith Super Glue involves understanding the nuances of each type. This table provides a quick comparison to help you match the adhesive to your specific project needs.

Insta-Cure+	Medium (Gap-Filling)	Versatile, bridges small gaps	Loose-fitting joints, general repairs, model building	5-10 seconds	Up to 3 hours	Most common materials (wood, metal, plastic, ceramic)
Maxi-Cure	Extra Thick	Fills larger gaps, slow set	Large gaps, most plastics, composite materials	30-60 seconds	Up to 3 hours	Plastics, fiberglass, wood
Super-Gold (Thin/Med)	Thin/Medium	Odorless, foam-safe, non-frosting	Foam, clear canopies, delicate materials	7-15 seconds	Up to 3 hours	Foam, clear plastics, wood, fabric
Instaflex	Medium	Flexible, clear, non-brittle	Anodized aluminum, flexible materials, high-stress joints	15-30 seconds	Up to 3 hours	Metals, rubber, some plastics requiring flexibility

The fast-setting nature of CA glues makes them incredibly efficient. However, it’s important to remember that while they set quickly, achieving maximum bond strength (full cure) can take several hours. Avoid putting significant stress on newly glued joints until they are fully cured to ensure the strongest possible bond.

How to Use Bob Smith Super Glues Safely and Effectively

Achieving a durable and reliable bond with Bob Smith Super Glues requires more than just applying the adhesive. Proper technique and safety precautions are essential.

Preparation Before Use

Before you even open the bottle, prepare your workspace and materials. Ensure the surfaces to be bonded are clean, dry, and free of dust, oil, or grease. Roughening smooth surfaces slightly with fine-grit sandpaper can sometimes improve adhesion. Work in a well-ventilated area to dissipate any fumes, especially with standard CA glues. Gather all necessary tools, such as clamps, applicators, and paper towels, beforehand. Wearing gloves and eye protection is highly recommended to prevent accidental skin or eye contact.

Correct Application Techniques

• Less is More: With Super Glue, a small amount goes a long way. Applying too much glue can actually weaken the bond and increase cure time.
• For Thin CA (Insta-Cure): Apply a small bead or a few drops to one surface. Press the parts together immediately. The glue will wick into the joint and set rapidly. For pre-assembled joints, apply the glue along the seam, and it will draw itself in.
• For Medium/Thick CA (Insta-Cure+, Maxi-Cure, Instaflex): Apply a thin, even layer to one surface. Bring the parts together and hold firmly for the recommended set time. For gap-filling applications, ensure the glue fully bridges the gap without excess. If using Insta-Set accelerator, apply the glue to one surface, spray the accelerator lightly on the other, then quickly join the parts.
• Clamping: For optimal bond strength, especially with larger or more critical assemblies, use clamps to apply consistent pressure while the glue sets and fully cures.

Handling Accidental Contact

Despite precautions, Super Glue can sometimes get on skin or clothing.

• On Skin: Do NOT pull apart skin that has been glued together. Instead, soak the affected area in warm, soapy water or use a commercial debonder (like BSI’s Insta-Off). Gently roll or peel the skin apart. Acetone (found in most nail polish removers) can also be effective, but test on a small skin area first.
• On Clothing: Super Glue can damage fabrics. Acetone might work but can also harm certain materials, causing discoloration or dissolving synthetic fibers. It’s often difficult to remove without leaving a trace.
• In Eyes: Immediately flush the eye with plenty of water for at least 15 minutes. Seek immediate medical attention. Do not try to pry the eyelid open forcefully.

“The secret to successful Super Glue application isn’t just about strength; it’s about precision. Using the right viscosity for the job and applying just enough adhesive can make all the difference between a temporary fix and a lasting bond.” – Dr. Elena Petrova, Adhesives Chemist

Choosing the Right Bob Smith Super Glue for Your Project

Selecting the ideal Bob Smith Super Glue from their extensive line is a critical step towards achieving a strong and lasting bond. It’s like choosing the right tool for a specific task – the better the match, the better the outcome.
