Improved Performance & Throughput

For insulating glass application, precise application of silicone materials is critical for delivering superior adhesion, durability and leak-free performance. Major manufacturers are moving away from tape-based applications and using automated dispense of adhesive and silicone materials. This approach provides a more consistent and complete seal. Learn more about window & door manufacturing efficiencies.

On-Ratio Meter, Mix & Dispense

The Graco ExactaBlend AGP is a variable ratio system that accurately meters, mixes and dispenses two-component medium to high-viscosity sealants and adhesives. It is used to seal and bond glass to metal or aluminum structures. Advanced pumping technology creates a better, more consistent bead – which results in reduced rework and less wasted material. For unique applications, Graco can also custom-engineer an equipment solution in our 130,000 square foot testing lab. Learn more about the Exactablend AGP.
