This is not a defect in the glue, but a natural chemical reaction:

👉 During curing, cyanoacrylate glue releases active vapors that react with traces of sweat or grease on the surfaces.

Result: a white haze (“whitening” effect) that spoils the appearance of the piece, especially if it’s transparent or glossy.

❗ Common mistake: It’s not just from your fingers — it can also come from those who handled the parts before you.

👉 Invisible fingerprints can remain on the surface and interact with the glue’s vapors.

✅ How to prevent white haze? –

The Colle21 protocol

To ensure a clean, invisible, and long-lasting bond, follow these best practices:

  1. Thoroughly degrease the parts to be glued

  2. Use isopropyl alcohol and a microfiber cloth to remove all traces of grease or dust.

  3. Clean your hands too!A simple wipe with a cloth or alcohol is enough. 🔒 Ideally, wear nitrile gloves to avoid any contact.

  4. Do not touch the parts after cleaning

  5. Handle them with tweezers or keep your gloves on.

🔧 Colle21 tip:

👉 Take a cotton swab, lightly soak it with olive oil, and gently rub the affected area.

✨ In just a few seconds, the white haze disappears without damaging the surface!

💡 Works very well on smooth plastic, glass, metal, or transparent materials.

To make the right choice, you first need to know the different glue families.

PVA (Polyvinyl Acetate) Glue

The most common type. White when applied, it turns transparent as it dries.

Perfect for solid wood or plywood. However, it has poor water resistance.

Polyurethane Glue

Extremely strong, ideal for outdoor use. It resists humidity and extreme temperatures.

Cyanoacrylate Glue

Ideal for small repairs or precise bonding, such as frames or mouldings. 

Colle21 is an effective and professional example.

Epoxy Glue

Two-component and very powerful, often used for structural assembly or heavy-duty repairs.

Why choose Colle21 wood glue?

Strength and precision Colle21 Wood Glue is particularly appreciated for its versatility and reliability.

It allows for precise bonding without smudges and ensures excellent long-term hold, even on the most demanding woods.

Ever noticed that sometimes your glue holds perfectly… and other times, not at all?

🧩 It’s not (just) the glue — it’s also the climate.

Humidity, heat, cold, and even wind can drastically change how your glue behaves, even if it’s professional quality like Super Glue Cyano Colle21.

🔍 Why do temperature and humidity matter so much?

Cyanoacrylate glues, like those in the Colle21 range, chemically react to the humidity in the air and within materials.

Here’s what you need to know:

🌬️ Too low temperature:

  • The polymerisation process slows down significantly.

  • The glue seems “inactive” or takes more than 60 seconds to set.

  • Increased risk of incomplete bonding.

🔥 Too high temperature:

  • The glue may become thinner or overly fluid.

  • It can saturate porous surfaces, weakening adhesion.

  • Cures faster but sometimes too abruptly, causing whitening or stress.

💧 High humidity:

  • Speeds up the chemical reaction → ultra-fast setting.

  • May cause a “rubbery” effect if pieces are misaligned.

  • Can sometimes lead to whitening (“white haze” effect).

🌵 Air too dry:

  • Greatly slows down the setting.

  • Requires an activator to compensate for the lack of moisture.

🛠️ Pro tips for gluing in all conditions

✅ 1. Work at room temperature (18–25°C)This is the ideal range for cyanoacrylate glue.

✅ 2. Use an activator if the air is too dryColle21 Activator speeds up curing without compromising bond strength.

✅ 3. Slightly warm surfaces in winterA simple hairdryer can bring materials back to the right temperature.

✅ 4. Avoid direct moistureAlways wipe parts if in doubt (sweat, condensation, rain…).

When looking for a Superglue Colle21 two-component adhesive that can withstand gasoline, it’s not just about bonding two parts together.

You need an ultra-high-performance adhesive, such as a two-component epoxy glue specially formulated for plastics exposed to hydrocarbons, capable of resisting vibrations, hydrocarbons, and extreme conditions.

Whether it’s to repair a car part, a fuel tank, a motorcycle accessory, or a tool exposed to gasoline, not all glues are suitable.

⚠️ Why gasoline damages most glues

Gasoline contains powerful solvents that break down the polymers in many adhesives.

Unsuitable glues soften, crack, or lose their bonding power over time.

The solution: choose a professional-grade cyanoacrylate glue specifically formulated to resist gasoline — like Superglue Colle21, tested under real-world conditions.

🔍 The best gasoline-resistant glue

For a reliable, long-lasting repair, we recommend :

🔒 4 steps for an optimal gasoline-resistant bond

1️⃣ Thorough surface preparation Use Lime21 to clean, sand, and degrease the bonding area.

2️⃣ Precise glue application Apply Superglue Colle21 using its fine nozzle for perfect, targeted dosing.

3️⃣ Accelerating the bond Speed up curing instantly with Activator21 Spray or Activator21 Liquid.

4️⃣ Reinforcing the repair Add Magicdust21 to fill and harden the area, ensuring maximum resistance to hydrocarbons.

✅ A: To effectively bond rigid plastic, the best solution is to use a Super Glue cyano Colle21, reinforced with Primer21.

Rigid plastics (such as ABS, hard PVC, or certain technical plastics) have a low-porosity surface, which makes adhesion more challenging.

That’s why applying a primer before the glue is highly recommended.

💡 Primer21 activates the surface of the plastic for instant and long-lasting adhesion, even on the most stubborn materials.

🔎 Then, you can choose the Super Glue cyano Colle21 best suited to your needs:

🛠️ The 4 key steps for perfect bonding on rigid plastic:

A: Having super glue on your fingers can be uncomfortable and, in some cases, dangerous if handled without care. Colle21 cyanoacrylate Super Glue is not toxic once dry, but it bonds instantly to the skin, which can cause accidental finger adhesion or small chemical burns if you try to forcefully pull it apart.

If you have super glue on your fingers:

  • ❌ Never pull your fingers apart, as this could tear the skin.

  • ✅ Use an appropriate remover such as Debonder21 or Acetone21.

  • 💧 Soak in warm soapy water to soften the glue before attempting any separation.

🛠️ 4 steps to avoid accidental bonding during your projects:

1️⃣ Prepare the surface and protect your hands – File, clean, and degrease the parts with Lime21.

2️⃣ Apply precisely – Use the Colle21 Precision Nozzle to avoid glue drips on your skin.

3️⃣ Quick and controlled bonding – Speed up adhesion with Activator21 Spray.

4️⃣ Strengthen assemblies – Use Magicdust21 to fill gaps or reinforce if needed.

⚠️ Key points to remember:

  • Super glue on your fingers is dangerous if you try to remove it dry.

  • Always wear gloves for prolonged work.

  • Keep a remover like Debonder21 on hand in case of an accident.

A Primer (or undercoat) is a preparatory layer applied before painting.

It improves paint adhesion, ensures uniform coverage, and extends the lifespan of the coating.

This “bridge” role between the surface and the paint is essential to achieve a professional and long-lasting result, especially on porous or smooth materials such as wood, metal, or resin.

A Primer is a base coat designed to prepare the surface before applying the finishing paint.

It improves adhesion, evens out the texture, and extends the lifespan of the paint.

Without a primer, the paint may peel or absorb unevenly.

  • Prepare the spray: place the can in hot water for a few minutes, then shake it vigorously for 30 seconds.

  • Spray evenly: hold the can 15–20 cm from the surface and apply light coats, crossing your strokes.

  • Let it dry: wait 15 minutes before handling the pieces and 45 minutes for a perfect set.

This method ensures a smooth and durable undercoat, ready for your paint application.
