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.
Extra-Fine Hollow Needle: Allows for incredibly precise application, perfect for attaching tiny components and reaching difficult areas. This minimizes excess glue and enhances detail work.
Liquid Plastic Welding Formula: Unlike traditional glues, it gently melts and welds plastic surfaces together, creating a strong, permanent, and seamless bond that becomes part of the model itself.
Ideal for Clear Parts: Specifically formulated to be used on the edges of clear components (e.g., canopies, windows) without causing the common 'fogging' effect seen with some other glues, maintaining optical clarity.
Professional Grade Quality: Designed for serious modelers, ensuring reliable performance and high-quality results for intricate plastic model kits.
Capillary Action Application: The low viscosity allows the glue to flow into seams via capillary action, requiring only a small touch of the needle to the joint, which then draws the glue along.
Generous 25g Size: Provides ample glue for multiple projects, offering good value and reducing the need for frequent replenishment.
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.
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.

Revell Contacta Professional is engineered for modelers who demand precision and a strong, clean finish. Its core strength lies in its ability to weld plastic, creating a bond that is physically part of the model, rather than just an adhesive layer.
Preparation: Ensure parts are clean, free of dust, and fit together well without gaps. Dry-fit components before applying glue.
Precise Application: Lightly touch the extra-fine needle to the seam where two plastic parts meet. The glue's low viscosity will draw it into the joint through capillary action. Only a tiny amount is needed.
Hold Firmly: Once applied, hold the parts together firmly for a few seconds to allow the plastic to melt and weld. A strong initial bond forms quickly.
Drying Time: While a surface bond forms rapidly, allow several hours for a full cure, especially for stress-bearing joints. For best results, let parts sit undisturbed for 24 hours.
Attaching Small Details: Ideal for delicate parts like antennas, railings, cockpit levers, or photo-etched plastic details where a tiny, controlled dab of glue is crucial.
Seamless Fuselage/Wing Joints: Apply along the inside edge of one half, press the second half into place, then run the needle along the outside seam. The glue will be drawn into the joint, creating a smooth transition.
Securing Clear Canopies: Apply a very thin bead along the mating edge of the canopy. The glue won't fog the clear plastic, ensuring excellent visibility. Use sparingly to avoid visible residue.
Repairing Broken Plastic Parts: For clean breaks in polystyrene, this glue can often create an almost invisible repair by welding the pieces back together, restoring structural integrity.
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.
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.
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.
