Frequently Asked Questions About Autoshield NP60
Q: Why is the 1-hour drive-away time so critical from an engineering perspective?
A: The 1-hour drive-away time, validated by the FMVSS 212 crash test, signifies that the adhesive has achieved sufficient cohesive strength and modulus to safely restrain the windscreen during a collision. This ensures correct airbag functionality and maintains the structural integrity of the passenger safety cell. It's not just about speed; it's a certified measure of performance under critical load.
Q: Can I really use this without a primer? What's the risk?
A: Autoshield NP60 is engineered for primerless adhesion specifically to clean, abraded automotive ceramic frit bands. It is not primerless on plain glass, which requires the specified Activator and Primer. The risk of omitting the required surface preparation is adhesion failure, as the adhesive cannot form a proper chemical bond to an unprepared or contaminated substrate, compromising the entire installation.
Q: What actually happens if I apply NP60 in 10°C weather?
A: At 10°C, the moisture-curing reaction slows significantly. While the product can be applied down to 5°C, the skin formation time and the time to reach a safe drive-away strength will be at least double the time specified at 23°C. For a safe installation, you must extend the cure time accordingly; the 1-hour drive-away is only valid at 23°C / 50% RH.
Q: The TDS mentions "high modulus." What does this mean for the vehicle?
A: "High modulus" means the cured adhesive is very stiff and resistant to deformation under load. For a vehicle, this is crucial. A high modulus adhesive makes the windscreen a true structural component, restoring the car's original torsional rigidity. This improves handling, reduces squeaks and rattles, and is essential for the proper function of the vehicle's safety systems.

Applying Autoshield NP60: Protocols & Best Practices
General Application Steps:- Preparation: Ensure substrate is clean, dry, and prepared precisely as per the Adhesion & Preparation Guide. Ensure sealant and substrates are within the recommended application temperature range (5°C to 35°C).
- Application: Cut the nozzle to produce a triangular bead of the appropriate size. Apply with a steady, consistent pressure using a professional-grade caulking gun, ensuring a continuous, unbroken bead.
- Tooling & Finishing: No tooling is typically required. Position and press the glass into the adhesive within the 20-35 minute skinning time to ensure proper wet-out and contact with the bond line.
- Curing: The vehicle can be safely driven away after 1 hour at 23°C / 50% RH. Protect the bond from significant water exposure until fully cured (approx. 3mm per 24 hours).
For Automotive Technicians: Side Glass Bonding
The Engineering Challenge: Bonding a fixed side glass panel (e.g., quarter glass) where clamps are difficult to apply and rapid handling strength is needed to continue reassembly of the vehicle's interior trim.
The System-Based Solution with Autoshield NP60: The high green strength of Autoshield NP60 is a key advantage here. It develops initial grab very quickly, which helps to hold the glass in place with minimal taping or support, preventing it from sliding or moving while the adhesive cures. The rapid cure profile means interior components can be reinstalled sooner, improving overall job efficiency.
Best Practice Note: Ensure the old sealant bed is mechanically trimmed back to a uniform layer of 1-2mm. Never remove it completely, as this provides an ideal surface for the new adhesive to bond to. Do not clean the old sealant with any alcohol-based products.
Limitations & Safety Protocols
Limitations:- Do not apply at temperatures below 5°C. In lower temperature ranges (5°C to 15°C), all cure and drying times must be doubled.
- Do not apply in the presence of, or in direct contact with, cured or uncured silicone or hybrid (MS, SPUR, STPE) sealants, as this will inhibit the cure and compromise the bond.
- Not suitable for use on substrates where bleed-through may be an issue (e.g., natural stone).
