- Rapid Initial Grab: Achieves initial grab in just 15 minutes, significantly optimizing assembly line throughput and production efficiency.
One Adhesive, Infinite Applications
CHEMPU PUR 15 is designed for high-performance structural bonding across diverse substrates. Requirement: At least one substrate must be porous.
- Hardwoods & Softwoods: Ideal for doors, window frames, and outdoor furniture.
- Metals & Laminates: High-strength bonding for industrial panelling.
- Synthetics: Compatible with PVC, Fibreglass, and Polyurethane foams.
- Sandwich Panels: Perfect for Polystyrene-nucleus structural panels.


How to Achieve a Perfect Bond
- Preparation: Surfaces must be clean, dry, and free from dust or grease.
- Application: Apply PUR 15 to one surface (preferably the less absorbent one) using a roller or beading nozzle.
- Clamping: Press parts together firmly within 25 minutes. The moisture-curing process will initiate immediately.
- Curing: Allow 24 hours for maximum chemical and mechanical resistance.

Can CHEMPU PUR 15 be used for outdoor projects?
Absolutely. With its EN 204 D4 rating, it is specifically designed for outdoor structural wood bonding exposed to weather.
What is the shelf life of this PUR glue?
It can be stored for 12 months in original packing at 5°C – 25°C. Keep away from heat sources to maintain stability.
Why does one surface need to be porous?
PUR 15 is moisture-curing. Porous surfaces (like wood or cement) allow the adhesive to interact with ambient moisture to complete the chemical bond.
