    The Austin Hardware® Sealants and Adhesives Blog Series: Seam Sealants Pre and Post E-Coat

    Posted by David Plunkett on Jan 12, 2024 11:02:37 AM

    In the complex automotive manufacturing world, achieving a perfect balance between structural integrity, aesthetics, and durability is paramount. One often overlooked yet crucial component in this process is seam sealer. Seam sealers play a vital role in enhancing the overall performance and longevity of vehicles, particularly in the presence of pre- and post-e-coat processes.

    Seam sealants are commonly used in the automotive industry to seal joints, seams, and gaps in vehicle bodies to prevent water, dust, and other elements from penetrating and causing corrosion, subsequently enhancing the overall durability of the vehicle.

    Their application occurs at various stages of the manufacturing process, including both pre-electrocoat (e-coat) and post-e-coat stages.

    Electrocoating, or e-coating, involves immersing the vehicle body in a tank of electrically charged paint particles. The paint adheres to the metal surfaces electrostatically. After applying the e-coat, the vehicle body goes through a bake oven, where the paint is cured. The high temperature in the oven helps the e-coat form a durable, protective layer.

    It's essential to use seam sealants that are compatible with the e-coat process and can withstand the high temperatures of the bake oven. Proper surface preparation and application techniques are also crucial to ensure adhesion and effectiveness.

    The pre-e-coat phase involves the application of an electrically charged coating to the vehicle's metal surfaces to prevent corrosion. However, even with the protective layer of e-coat, there are vulnerable areas where water and other environmental elements may penetrate. This is where seam sealers come into play.

    Pre-e-coat seam sealers have two significant functions. They function as an added barrier against corrosion and contribute to the vehicle's structural integrity.

    The Austin Hardware® Sealants and Adhesives Blog Series: A Guide to Bond Strength

    Posted by David Plunkett on Nov 30, 2023 11:30:00 AM

    Bond strength is a comprehensive measure of an adhesive's ability to hold two substrates together. It measures the resistance to separation and is affected by various factors, including the type of adhesive used, the bonding surface preparation, and the bonding process.

    To fully understand the bond strength of an adhesive, it's necessary to understand the types of stress imparted on adhesive joints. The most common stresses include shear, peel, tensile, compression, and cleavage.

    All these terms relate to the integrity of adhesive joints while measuring different strength aspects of the adhesive's performance. Below is a summary of each.

    Shear strength measures an adhesive's resistance to forces parallel to the bonded surfaces. It represents the adhesive's ability to withstand pull directed across the adhesive, forcing the substrates to slide over each other. It is commonly tested by subjecting the bonded materials to a force applied parallel to the adhesive joint. A strong adhesive joint should exhibit both high bond and shear strength.
