Product Information
Full details
This guide is for plastic model builders seeking precise application and a strong, seamless bond. Revell Contacta Professional Liquid Glue offers micro-fine gluing for intricate details and clear parts thanks to its extra-fine hollow needle, providing a professional finish by welding plastic surfaces. Its primary limitation is that it's designed specifically for polystyrene plastic, not universal use.

FAQs
What kind of plastic does Revell Contacta Professional work on?
It is specifically formulated for polystyrene (PS) plastic, which is the most common plastic used in injection-molded model kits. It is not suitable for other materials like resin, metal, vinyl, or other types of plastics like ABS.
Can I use this glue on clear parts, like canopies?
Yes, it is designed to be used on the edges of clear plastic parts without causing the 'fogging' or 'frosting' effect that some other plastic cements can cause. Apply it sparingly and precisely to the mating surfaces.
How long does it take for the glue to dry?
An initial bond forms very quickly, often within seconds, allowing you to hold parts together. However, for a full, strong, and permanent weld, it's recommended to allow at least several hours, ideally 24 hours, for the glue to fully cure.
How do I prevent the needle from clogging?
Always recap the bottle immediately and tightly after every use. Storing the bottle upright also helps. If a clog occurs, refer to the troubleshooting section for instructions on how to clear it with a fine wire.
What is the difference between this and traditional tube cement?
Revell Contacta Professional uses an extra-fine hollow needle for highly precise application and its liquid formula "welds" the plastic by slightly melting the surfaces together for a stronger, more seamless bond. Tube cements are often thicker, less precise, and can be messier.
Do I need good ventilation when using this product?
Yes, like most plastic cements, Revell Contacta Professional contains solvents that release fumes. Always use the product in a well-ventilated area to ensure your safety and comfort.
What should I do if I get glue on my skin?
If skin contact occurs, wash the affected area immediately with soap and water. If irritation persists, seek medical advice. Avoid prolonged skin contact and do not ingest.
Troubleshooting
Glue is not flowing from the needle.
Check if the cap is fully removed. The needle might be clogged; try gently squeezing the bottle to dislodge any dry glue. If persistent, carefully insert a fine wire (e.g., from a bread tie or a fine sewing needle) into the hollow needle to clear the blockage. Ensure the wire is smaller than the needle's bore to avoid damage.
Too much glue is being dispensed.
Revell Contacta Professional relies on capillary action. You only need to touch the needle to the joint. Avoid squeezing the bottle unless absolutely necessary for initial priming. Practice on a scrap piece to get a feel for the minimal pressure required.
The bond feels weak or parts separate easily.
Ensure both surfaces are clean and free of paint, dust, or mold release agents. Dry-fit the parts to ensure a tight fit before gluing. After applying glue, hold the parts firmly together for at least 10-20 seconds to allow the plastic to melt and weld. Allow sufficient curing time (up to 24 hours) before handling roughly.
The glue is drying too quickly in the needle during use.
This often happens if the cap is left off for too long. Always recap the bottle immediately after each use, even for short breaks. If it clogs, refer to the solution for 'Glue is not flowing from the needle'.
Glue has created a visible mark or melted surface detail.
This indicates over-application. Revell Contacta Professional is very potent. For future applications, use an even smaller amount and allow capillary action to draw it in. For existing damage, allow the glue to fully cure, then very carefully sand and polish the affected area if possible. For deep damage, model putty may be required.
Pros and Cons
Pros
- Exceptional Precision: The fine needle allows for very accurate glue placement, especially for small parts and tight spaces.
- Strong, Permanent Bond: "Welds" plastic together for a robust and durable connection that won't easily break.
- Invisible Seams: When applied correctly, the welded bond creates a nearly invisible seam, enhancing the model's appearance.
- Safe for Clear Parts: Formulated to prevent fogging or frosting on transparent plastic components.
- Efficient Capillary Action: Glue flows easily into joints, making assembly quicker and cleaner.
Cons
- Material Specific: Exclusively designed for polystyrene plastic; not suitable for other materials like resin, metal, or vinyl.
- Quick-Drying Nature: Requires quick and accurate placement as there is limited repositioning time once applied.
- Potential for Excess: Care must be taken not to apply too much, as it can damage surface detail due to its melting action.
- Fumes: Like most plastic cements, it produces fumes, requiring good ventilation during use.
Setup, Compatibility & Care
Initial Setup
- Uncap: Twist the cap to remove it. You may hear a slight hiss as pressure is released.
- First Use: If the needle seems blocked on first use, gently press the bottle to check for flow. A fine wire (not included) can be used to clear a stubborn blockage, but this is rare for a new bottle.
Compatibility
- Compatible With: Primarily designed for polystyrene (PS) plastic model kits. This includes the vast majority of injection-molded plastic models from brands like Revell, Tamiya, Hasegawa, etc.
- Not Compatible With: Does not work on other materials such as resin, metal, vinyl, PE (photo-etched) parts (unless they are plastic-coated), clear styrene other than the edges (can cause frosting if applied directly to viewing areas), or other types of plastics like ABS or polypropylene. Always test on scrap plastic if unsure.
Product Care
- Storage: Always recap the bottle tightly immediately after use to prevent the needle from clogging and the solvent from evaporating. Store upright in a cool, dry place, away from direct sunlight.
- Needle Maintenance: If the needle becomes clogged, a fine wire (e.g., from a guitar string or a thin sewing needle) can be carefully inserted to clear it. Avoid forcing the needle as it could break.
- Cleanliness: Keep the exterior of the bottle clean. If glue gets on the outside, wipe it off promptly with a tissue to prevent build-up.
- Safety: Use in a well-ventilated area. Avoid prolonged skin contact and eye contact. Keep out of reach of children. If contact occurs, refer to safety data sheet or seek medical advice.
