What is INSTANT MV Medium Viscosity 90-140 and why choose it
Bostik INSTANT MV Medium Viscosity 90-140 is a one-component, ethyl cyanoacrylate-based adhesive designed for fast assembly of difficult-to-bond materials. Thanks to its medium viscosity and very rapid fixing times, it enables quick handling, high shear strength joints and uniform stress distribution across the bond line.
It offers excellent adhesion on a wide range of substrates including metals, plastics and elastomers, making it suitable for many general bonding operations where instant fixing and high final strength are required.
Main features
- Cyanoacrylate adhesive with medium viscosity (Brookfield 90–140 mPa·s at 25 °C).
- Very fast fixture times on many substrates (from about 5 to 20 seconds at 23 °C, depending on the material).
- High tensile strength on a variety of materials (for example, up to approx. 13–16 MPa on beech wood and 12–16 MPa on grit-blasted steel at 22 °C).
- Adhesion to multiple materials including metals, plastics and elastomers.
- High shear strength and uniform stress distribution in the bonded joint.
- Transparent to slightly yellow colour for discreet joints.
- Designed for rapid assembly processes and quick handling.
Technical specifications
- Chemical base: Ethyl cyanoacrylate.
- Product type: One-component cyanoacrylate adhesive.
- Viscosity (Brookfield, 25 °C): 90–140 mPa·s.
- Colour: Transparent or slightly yellow.
- Physical state: Liquid.
- Density (liquid): Approx. 1.08 g/ml.
- VOC content: Approx. 18 g/L.
Fixing times at 23 °C
- Beech wood: approx. 10–20 s.
- Mild steel: approx. 5–15 s.
- ABS: approx. 5–15 s.
- Polycarbonate: approx. 5–15 s.
Tensile strength at 22 °C

- Aluminium: approx. 4–6 MPa.
- Polycarbonate: approx. 10–11 MPa (substrate failure).
Handling and curing
- Surfaces must be clean, dry and free from grease before application.
- Apply the adhesive to one surface only. Do not spread with tissues or brushes.
- Assemble the parts correctly aligned; the very short fixing time leaves little opportunity for adjustment.
- Keep parts in position until the adhesive has fixed.
- Allow the joint to develop full strength before loading (typically 24–72 hours after assembly, depending on bond line, materials and environmental conditions).
Storage
- Shelf life (unopened at 23 °C): approx. 12 months.
- Store in a cool, dry place protected from light.
- For best long-term performance, refrigerate at approx. 4–8 °C.
- Protect from moisture; the product cures on contact with humidity.
Applications and use cases
INSTANT MV Medium Viscosity 90-140 is designed for fast assembly where high strength and rapid handling are essential.
Typical applications
- Rapid assembly of difficult-to-bond materials requiring uniform stress distribution and high shear strength.
- General purpose bonding of components made from metals, plastics and elastomers.
- Situations where transparent or nearly invisible bonds are desired.
- Industrial and maintenance operations that benefit from short fixing times and quick return to service.
FAQ
-
What type of adhesive is INSTANT MV Medium Viscosity 90-140?
It is a one-component, ethyl cyanoacrylate-based adhesive with medium viscosity.
-
Which materials can it bond?
According to the technical data, it adheres to a wide range of materials including metals, plastics and elastomers, with specific performance data given for beech wood, steel, aluminium, ABS and polycarbonate.
-
How fast does the adhesive fix?
Fixture times at 23 °C typically range from approximately 5 to 20 seconds, depending on the substrate.
-
When can the bonded assembly be loaded?
Full strength is generally reached between 24 and 72 hours after assembly, depending on joint gap, materials and environmental conditions.
-
How should surfaces be prepared?
Surfaces must be clean, dry and free of grease before applying the adhesive.
