Adhesive Primer K2 WC70 for Cyanoacrylate Glues 20 ml

K2 WC70 Adhesive Primer is a 20 ml surface activator formulated to improve the performance of cyanoacrylate (super glue) adhesives on porous, low-energy, or difficult-to-bond substrates. The clear primer conditions surfaces to accelerate cure and increase bond strength of cyanoacrylate glues, enabling more reliable joints for small repairs and precision bonding tasks in workshops, hobby projects, and light industrial applications.

Advantages

The primer reduces surface tension and removes microscopic contaminants that can inhibit cyanoacrylate curing, resulting in faster set times and stronger adhesive joints. Its compact 20 ml dispenser allows controlled application to small areas and crevices, minimising waste. K2 WC70 is suitable for use with a wide range of substrates commonly bonded with cyanoacrylates, improving consistency and reliability of repairs without requiring extensive surface preparation.

Suitable for

• Small repairs and precision bonding of plastics
• Bonding rubber and elastomeric parts
• Joining porous materials where super glue alone gives weak bonds
• Quick spot repairs in hobby, DIY and light industrial settings

Key specifications

• Volume: 20 ml
• Compatibility: Designed for use with cyanoacrylate (super glue) adhesives
• Formulation: Surface primer/activator for enhanced adhesion
• Appearance: Clear liquid suitable for precision application

How to use

Ensure surfaces are clean, dry and free of oils, grease or dust before application. Apply a small amount of the primer to one or both mating surfaces using the applicator or a suitable tool, then allow the primer to evaporate briefly (follow manufacturer’s guideline times if available). Immediately apply the cyanoacrylate adhesive and press the parts together. Hold or fixture the parts until the adhesive cures; primer accelerates cure but actual set time varies with adhesive type and environmental conditions.

Usage recommendations

Use in a well-ventilated area and avoid prolonged skin contact. For best results, test on a small inconspicuous area or sample of the substrate before full application. Store the product capped in a cool, dry place away from direct heat and ignition sources. Keep out of reach of children.
