High Strength with Extended Open Bond Time
3M™ Heavy Duty 20CA Spray Adhesive is a clear, high-strength adhesive that bonds a range of large surfaces and is perfect for large-scale laminations. It shows aggressive initial tack with an extended open bond time of up to one hour. The lace spray pattern with high solids content supports the low soak-in property and provides high coverage. The combination of fast tack, strong bond and clean appearance make it ideal for large bonding projects. This adhesive is GREENGUARD™ certified, helps contribute to LEED® credits and meets CARB and OTC VOC requirements.*
