Summary:Jun 25,2026
Long curing time occupies factory warehouse space and delays delivery schedules, a major pain point for packaging converters. LF 2077 matched with LF 2188 features fast curing speed to accelerate your whole production workflow.
After duplex lamination, laminates can be rewound and slit after only 1 day. Triplex composite production can start 24 hours after duplex processing, greatly shortening waiting time for secondary compounding. Under recommended 35–45°C curing temperature, the adhesive forms complete crosslink structure in merely 3–5 days to gain full boiling and retort resistance, far faster than many common solvent-free adhesives on the market.
The mixed adhesive offers stable initial bonding strength, no film sliding during winding. It is compatible with all mainstream printing inks and produces zero bubbles during high-speed coating. The viscosity parameters of main agent and hardener are stable, matching automatic two-component continuous dosing machines for stable long-run production.
Dry coating weight ranges 1.2–3.2 g/m², adjustable for printed and unprinted films. When machine stops over 30 minutes, clean coating unit to prevent gel blockage and machine downtime loss. The product holds full FDA, EU and GB 9685 food safety certifications, suitable for all heat-resistant food packaging. If you hope to improve warehouse turnover and shorten delivery lead time, LF2077/LF2188 is your ideal fast-curing solution.
