Product Information
Full details
The Demsun A32 Express Rapid Bond Adhesive is a high-performance, single-component polyurethane adhesive designed for professional contractors and DIY enthusiasts who require quick, reliable bonds for interior trim, skirting, and architraves. Its primary benefit is a rapid 15-minute cure time that significantly accelerates project timelines, though users should note that the fast-setting formula requires precise application and quick alignment of materials before the bond locks into place.

FAQs
Can I use this for outdoor projects?
While it features excellent water resistance, it is primarily designed for internal applications like skirting and architraves.
How long until it is completely dry?
The adhesive reaches a tack-free state in 15-20 minutes, though full structural curing continues over the following hours.
Do I need a special gun to use this?
No, it is compatible with all standard 310ml caulking guns.
Is it paintable?
Yes, once the adhesive is fully cured, it can be painted over to match your walls or trim.
What is the recommended application temperature?
For best results, apply the adhesive in temperatures between +5C and +40C.
Does this adhesive work on metal?
It is optimized for wood and porous construction materials; adhesion to non-porous metals may be significantly weaker.
Troubleshooting
Adhesive is curing too slowly
Verify that the ambient temperature is at least +5C and that the surfaces are clean and dry, as humidity and temperature influence cure rates.
Difficulty extruding the adhesive
Ensure the cartridge nozzle is cut at the correct angle and size, and check that the caulking gun mechanism is functioning correctly.
Bond is not holding firmly
Confirm that the bonding surfaces are porous and compatible with polyurethane adhesives; remove any loose paint or debris that may be preventing a direct bond.
Pros and Cons
Pros

- Strong, professional-grade polyurethane bond
- Paintable finish allows for aesthetic integration
- Water-resistant properties
- Easy to apply using a standard caulking gun
Cons

- Requires proper surface preparation for optimal adhesion
- Limited to specific temperature application range
- White color may show through light-colored gaps without painting
Setup, Compatibility & Care
To ensure optimal performance, ensure all surfaces are clean, dry, and free of dust or grease before application. Apply the adhesive using a standard 310ml cartridge gun. The adhesive is formulated for application at temperatures between +5C and +40C; applying it outside of this range may negatively impact the cure speed and final bond strength. After application, ensure that components are aligned quickly due to the rapid set time. Store the cartridge in a cool, dry place and ensure the nozzle is sealed properly if the entire tube is not used in one session to prevent premature curing within the tip.
