EternaBond® WindowSeal for Newly Installed Windows

March 26, 2020

The installation of new windows requires the use of an efficient sealant to ensure a secure, weatherproof fit. While there are many products on the market for this purpose, most are not as high quality as the EternaBond® WindowSeal is for the task. It consists of a polyethylene film and is coated with the EternaBond® MicroSealant. As a result, it fuses to all types of construction materials ranging from wood to concrete to seal the gap between the exterior sheathing and the window securely. Along with this, it does not shrink or peel and is suitable for even cold temperatures since it gives rather than being rigid. We explore this product in further detail in the following.

The Materials That WindowSeal Contains

WindowSeal includes the latest in EternaBond’sMicroSealant technology that is 100-percent solids formulation of thermoplastics, non-curing and non-butyl rubber, thermoplastics and a built-in primer. A low-density polyethylene or LDPE backing is bonded to this formulation and a protective silicone release liner is added to protect the finished product. You must remove the liner to apply the WindowSeal.

Preparation for Installation and the Application Process

Prior to installation of the WindowSeal, you must clean and dry the surface. You need to remove any dirt, dust, moisture and other unwanted elements along with grease or oil if either is present. The application is simple once you perform this action. Just remove the release liner slowly to keep the adhesive from becoming contaminated. Install the WindowSeal by applying pressure with a steel roller or your hand to activate the bonding process. Temperatures of 4.44444-degrees C to minus 28.8889-degrees C require that you also apply EternaPrime for secure adhesion.
