Description

oProfessional PVC Cold-Welding Adhesive

Würth FSK System Adhesive is a vinyl chloride polymer-based adhesive developed for high-strength cold welding of hard PVC materials. Its advanced formulation ensures reliable bonding for demanding construction, sanitary, and trade applications.

Precise, User-Friendly Application

The adhesive’s thixotropic setting prevents dripping during vertical or overhead applications, making it highly practical for construction sites and workshop use. It is designed for gap-bridging up to 0.1 mm, enabling friction-locking joints with minimal adhesive bleed-through.

Durability and Resistance

Once cured, the adhesive forms a weatherproof and UV-resistant bond, making it suitable for outdoor installations such as plastic windows, cover strips, and structural PVC profiles. It provides long-lasting resistance to water, petrol, oil, and alcohol, and offers short-term resistance to diluted acids and lyes.

Fast and Strong Bonding

With a functional strength achieved within 2–4 minutes, the FSK adhesive enables quick handling, while full curing occurs within 24 hours (at 20°C). Depending on load and material, complete hardness may take up to 8 weeks.

Applications

  • Plastic window construction - bonding angular fillets, cover strips, and hard PVC profiles.
  • Sanitary and plumbing work - cold welding of PVC pipes (excluding high-pressure).
  • Trade fair and sign construction - bonding rigid foam panels and structural PVC boards.
  • Vehicle and construction applications - joining non-pressurised hard PVC components.

More Information

Application Instructions

  1. Clean PVC bonding surfaces thoroughly with Würth Cleaner Type 10 to remove dirt, grease, and contaminants.
  2. Apply a thin, even layer of the adhesive to one side of the joint.
  3. Press the components together immediately (within 30-60 seconds) and hold until functional strength is achieved (2-4 minutes).
  4. Adhesive reaches handling strength after a few minutes, full curing after approx. 24 hours.

Usage Notes

  • Processing temperature range: 5°C to 35°C.
  • Adhesive consumption: approx. 8g per metre for a 20mm wide bar / max 400g/m^2 in surface bonding.
  • Use in well-ventilated areas.
  • Avoid over-application to prevent weak points or bleed-through.

Safety Warnings

  • Flammable - flash point -14°C. Keep away from sparks, flames, and hot surfaces.
  • Contains solvents - use onl with adequate ventilation.
  • Avoid skin and eye contact; wear protective gloves and goggles.
  • Store in a cool, dry place between 15°C and 25°C, away from sunlight.
  • Keep out of reach of children.
