Astral Vetra LV-401 – Low Viscosity Instant Adhesive

Astral Vetra LV-401: The Super-Penetrating Glue for Invisible Repairs

When you need to fix hairline cracks, stabilize porous surfaces, or bond components without visible glue lines, Astral Vetra LV-401 is the ultimate solution. This product is a specialized, low-viscosity (LV) cyanoacrylate (CA) adhesive engineered to utilize **capillary action**. It flows deeply into the tiniest gaps, seams, and cracks—as small as 0.05mm—creating an invisible, structural bond that standard thick glues cannot achieve. [Image of capillary action in adhesive]

Astral Vetra LV-401 is favored in assembly lines, model making, and high-precision repair work where speed and joint aesthetics are critical. It bonds instantly upon contact, saving significant clamping time and delivering professional-grade results on plastics, rubber, metal, and wood.

Why Choose Astral Vetra LV-401?

Its unique fluidity makes it a critical tool for specific applications:

• Capillary Penetration: The extremely thin consistency (similar to water) allows it to wick into pre-assembled parts and microscopic cracks, stabilizing the material from within.
• Instant Bond: Being a CA adhesive, it bonds almost instantly (3–10 seconds), drastically speeding up assembly and repair workflows.
• Invisible Joint: The low viscosity ensures the adhesive forms a minimal glue line, making the repair virtually invisible, especially on transparent or tightly fitted materials.
• Fast Fix for Porous Materials: Excellent for sealing and strengthening porous materials like foam, sponge, or unsealed wood before further processing.

Key Features of Astral Vetra LV-401

• Low Viscosity (LV): Highly fluid for maximum penetration.
• Cyanoacrylate Base: Provides an instant, strong bond on most common materials.
• Single Component: Ready to use straight from the bottle; no mixing required.
• Versatile Use: Bonds rubber, vinyl, plastics (excluding certain polyolefins), metal, and wood.

Recommended Application Areas

This penetrating super glue is vital for:

• Model Making & Hobby: Assembling intricate parts and securing tiny joints in plastic or wooden models.
• Electronics & Repair: Fixing miniature components or sealing fine cracks in plastic casings.
• Furniture Restoration: Stabilizing hairline cracks in veneers or securing loose joints where disassembly is impractical.
• Rubber Bonding: Fixing tears and bonding various types of rubber materials.

How to Use Astral Vetra LV-401

1. Preparation: Ensure surfaces are clean and dry. Since this is a penetrating adhesive, the two surfaces must be clamped or held together *before* application, with the gap being less than 0.1mm.
2. Application: Apply a single drop of Vetra LV-401 directly to the seam or joint. The glue will instantly wick (flow) along the entire seam via capillary action. Use sparingly; excess glue will not cure properly.
3. Curing: Hold the parts together firmly for 10-30 seconds. The bond will achieve full strength in 24 hours. For large surfaces or non-porous materials, use a CA accelerator spray to achieve an instant cure.
4. Storage: Store the adhesive tightly sealed in a cool, dark place to prevent curing from ambient moisture.

Frequently Asked Questions (FAQ)

Q: What is the maximum gap size it can fill?
A: Due to its low viscosity, it is optimized for gaps less than 0.1mm. For larger gaps, use a medium or high-viscosity CA glue.

Q: Is this glue waterproof?
A: When cured properly, the bond is highly water-resistant and suitable for applications exposed to moisture, though not recommended for prolonged water submersion.

Q: What if the glue runs onto the surface?
A: Since it cures instantly, it can leave a white residue (“blooming”). Work in a well-ventilated area and use acetone to wipe up excess immediately before it cures.
