MicroSeal was specifically and expressly designed in England many years ago to permanently replenish the natural protective agent that a sheep produces for its own coat. In addition to wear and stain protection, MicroSeal provides substantial sun fade resistance for the wool.
Without MicroSeal soil is naturally absorbed into the center of the wool fiber, hiding the dirt from the naked eye. Often consumers don’t realize their rug is dirty because they can’t see it. Unlike a typical fabric protector that only “coats” the fiber and then breaks up easily, MicroSeal penetrates the wool fiber to its inner cortex and protects it from the inside out. Not only from permanent stains and wear, but also from sun fade damage.
The Bead Test Comparison
A simple bead test of a coater solution (fluorochems or PTFE Resin) vs. MicroSeal (a penetrator) will sometimes result in the “apparent superiority of the coater.” This is because the coater will cover more of the space between the fibers while MicroSeal will penetrate and seal the individual fibers. Further testing simulating wear (manipulating the fabric, rubbing it, cleaning it, etc.) will result in the coater quickly breaking up and permanent stains on the fibers occurring thereafter. Even ordinary dirt can be difficult to vacuum because the broken coater material “hangs on” to the dirt.
The MicroSeal will not break up, wear off, or clean off and will continue to protect the fibers from permanent stains and sun fading for many years.
