Sealing / Gasketing

Dispense Solutions for Sealing and Gasketing

Sealing is the process of continuous bonding. Gasketing is the process of applying sealants.

Sealants are commonly applied around a perimeter using cure-in-place gasketing (CIPG) or form-in-place gasketing (FIPG). Either method provides a continuous liquid sealing surface between the housing and the cover to prevent dust and moisture from entering the interior of the unit and damaging sensitive components of electronics.

Sealants can be found in anything that needs protection from harsh environments like solar panels, tablets, or screens.

Warm-Applied Solar Panel Edge Sealant

A solar panel manufacturer improves its bead profile and application speed while removing quality issues related to the dispensed edge seal adhesive.

Solar Panel Edge Seal: Liquid-Applied vs. Tape

Uncover the advantages of pumpable solar edge tape (PSET) over traditional tape application methods for sealing solar panels.

Silicone Sealant for Solar Frame Attachment

Discover how a solar panel manufacturer improved bead profile consistency for solar frames using Graco automated silicone dispensing solutions.

Precision Dispense for Bonding and Sealing

When a product's functionality depends on a perfect bond or seal, dispensing an imperfect bead could lead to considerable cost implications.

Improved Sealing with Liquid Gaskets

Liquid gaskets offer superior sealing in a variety of applications

Comparing 1k Metering & Dispensing Systems

Shot size and flow rate, material properties, and manufacturing style are important when evaluating the correct metering system for single component sealants or adhesives.

Common electronic sealants include silicones, polyurethanes, physical foaming materials, and mixed foaming materials.

Electric Variable Ratio (EVR) Metering System

Change ratios without changing hardware. Simply program the electric variable ratio, meter mix dispense (MMD) system to move up to 6,400 cubic centimeters (ccs) per minute, while flexing dispense ratios between 1:1 to 5:1 or 2:1 to 10:1.

Precision Shot Meter (PSM) Dispense System

An innovative fluid path and robust construction make the precision shot meter (PSM) ideal for automatically dispensing one component epoxies, silicones, acrylics, urethanes, polysulfides and thermal interface materials (TIMs).

Progressive Cavity Pump

The Graco Progressive Cavity pump is a positive displacement valve that is used to move and dispense medium to high viscosity materials. As the rotor revolves, material transfers within the pump through a sequence of predetermined, discrete cavities. This provides a continuous flow while maintaining...

Sealant Supply Systems & Pumps

Graco's supply systems and pumps reliably deliver sealants and adhesives from a wide range of containers. Supply systems and pumps reliably move viscous materials at ambient temperature and can also provide warm and hot melt material conditioning. Designed with advanced pump and motor technologies, ...
