Vivtek V04 acrylic adhesive

Looking for Weld-On 4SC? Vivtek V04 is the replacement.

Vivtek V04 is an extremely low-viscosity, transparent solvent adhesive for bonding acrylic (PMMA), polycarbonate (PC) and various other rigid plastics. Thanks to its very low viscosity, V04 is ideal for capillary bonding, where the adhesive is applied to the joint using a fine needle or dispensing applicator.

V04 is a single-component adhesive and can be used straight from the container. No mixing of components is required.

Replacement for Weld-On 4SC

Vivtek V04 is the replacement for Weld-On 4SC.

V04 offers the same properties you would expect from a low-viscosity plastic adhesive for bonding acrylic: transparent, extremely low-viscosity and fast-reacting. This makes the adhesive particularly suitable for creating neat, precise plastic joints.

Suitable for various plastics

Vivtek V04 is suitable for bonding materials including:

• Acrylic/PMMA

• Polycarbonate (PC)

• ABS

• Polystyrene/PS

• PVC

• CAB

• PETG

The final bond strength may vary depending on the type of plastic. For unknown or specific materials, we therefore always recommend carrying out a test bond first.

Strength on different plastics

Vivtek V04 provides strong bonds on a range of rigid plastics. The strength achieved depends on the material and continues to increase as the bond cures.

V04 is also suitable for materials including ABS, PVC, CAB and PETG. For these materials, the final bond strength may vary depending on the type of plastic, surface condition and construction. For critical applications, we therefore always recommend carrying out a test bond first.

The bond strength develops gradually: after 24 to 72 hours, approximately 65–80% of the final strength is achieved. Allow approximately one week for the bond to reach maximum strength.

Ideal for capillary bonding

V04 is extremely fluid and has a viscosity comparable to water. This makes it particularly suitable for capillary application.

Position the parts to be bonded accurately against each other and apply the adhesive along the joint using a fine needle or dispensing applicator. The adhesive will naturally be drawn into the joint by capillary action. V04 can penetrate approximately 6 mm into the joint.

This method allows for highly controlled application and is ideal for acrylic constructions where a neat, clean bond line is required.

Fast curing

V04 reacts quickly. The initial bond forms within 1–2 minutes and the adhesive cures in approximately 3 minutes.

The bond then continues to gain strength. After 24 to 72 hours, approximately 65–80% of the final bond strength is achieved. Full bond strength is reached after approximately one week.

For acrylic, the typical shear strength is:

• 14.0 MPa after 24 hours

• 17.5 MPa after 7 days

Applications

Vivtek V04 is suitable for applications including:

• Acrylic boxes and structures.

• Displays and presentation stands.

• Signage lettering.

• POS and POP materials.

• Plastic housings.

• Transparent plastic structures.

• Model making.

• Plastic profiles.

• Alurapid and Elkamet materials.

Application

For good adhesion, surfaces must be clean, dry and free from grease. Degrease the parts to be bonded before applying the adhesive.

Capillary bonding

1. Position the parts accurately against each other.

2. Apply V04 along the joint using a fine needle or dispensing applicator.

3. Allow the adhesive to flow into the joint.

4. Wait a few seconds.

5. Gently press the parts together.

6. Allow the bond to continue curing.

Use as little adhesive as possible. Due to its very low viscosity, V04 spreads easily throughout the joint.

Please note when bonding machined acrylic: V04 contains solvents. Mechanically or thermally processed acrylic may therefore be susceptible to stress cracking. If necessary, allow processed acrylic to de-stress before bonding.
