Glue VALLEJO Ultra Glue for Photo-etch & Clear Parts Acrylic Waterbase 40 ml

VALLEJO Ultra Glue for Photo-etch & Clear Parts Acrylic Waterbase 40 ml is an acrylic, water-based adhesive formulated to bond photo-etched metal details and transparent plastic components used in scale modelling and miniature assembly. Supplied in a 40 ml bottle with a narrow applicator, the glue enables controlled placement on small parts and aims to minimize fogging or whitening on clear surfaces while producing a thin, nearly invisible joint.

Advantages

The formula is designed for precise application on fine metal and clear plastics, providing steady drying speed and low residue. As an acrylic waterbase adhesive, it reduces the risk of solvent damage to delicate clear parts and helps preserve optical clarity. The narrow-tip bottle supports accurate dosing for small model components and photo-etched parts without excessive overflow.

Suitable for

• Bonding photo-etched metal details to plastic or metal model components
• Attaching transparent parts such as canopies, windows and lenses without fogging
• Model building, scale kits, miniatures and diorama detailing
• Repairing small transparent or thin plastic pieces that require a clear joint

When it may not be suitable

This acrylic water-based adhesive is intended for fine modelling tasks and may not provide the same instant high-strength bond as solvent-based superglues on some materials. For heavy structural joints, large load-bearing plastics, or parts that require an extremely fast cure, a different adhesive type such as a cyanoacrylate or epoxy may be more appropriate. Users should also test compatibility with unusual plastics or paints on a scrap piece before full application.

Key specifications

• Type: Acrylic water-based adhesive
• Volume: 40 ml
• Application: Narrow-tip bottle for precise dosing
• Surface suitability: Photo-etched metal, clear plastics, general modelling materials
• Finish: Designed to leave a thin, low-residue, clear joint

How to use

Ensure mating surfaces are clean, dry and free from grease or dust. Apply a small amount of glue using the narrow applicator tip to one surface; position parts and hold until initial adhesion occurs. For transparent parts, apply minimally to avoid excess and check alignment before the glue sets. Allow sufficient drying time according to ambient temperature and humidity; avoid moving parts until the bond has fully cured. Clean the applicator tip after use and reseal the bottle to prevent drying.

What to consider before purchase

• Intended materials: best for photo-etched metals and clear plastics
• Bond strength: designed for fine detailing rather than heavy structural loads
• Drying time: slower than instant cyanoacrylates; allow full cure time
• Compatibility: test on scrap material if working with unfamiliar plastics or painted surfaces

Usage recommendations

Use minimal amounts for clear parts to prevent visible residue; hold parts steady during initial set and allow extended cure for maximum strength. Store upright in a cool, dry place and keep the applicator tip clean to maintain precise dosing.
