Koat-A-Roll® sizes are engineered to fit tightly around specific standard rollers. Be sure that you are using the correct size Koat-A-Roll® for the roller that you will be working with. Koat-A-Roll® is made in a standard 83 Shore 'A' Polyurethane in safety Orange and Black, 90 Shore 'A' Polyurethane in Green and 70 Shore 'A' FDA Polyurethane in Black
Koat-A-Roll® is stocked from 1.00” to 3.50” diameter, in 1/8” or 1/4” wall thicknesses, and 10’ lengths. Additional sizes, wall thicknesses, colors and hardnesses can be manufactured as a special order.
- When installing Koat-A-Roll®, wear a long sleeve shirt and gloves to protect yourself from the heat of the oven and the product.
- Begin by placing lengths of Koat-A-Roll® in a convection oven at 200°F, for 5 to 10 minutes. By heating the Koat-A-Roll®, it makes it easier to apply it to your roller. Even if an oven is not available to you be sure to use our K-Lube® Assembly Lubricant and the Kastalon Installation Nozzle.
- Place the roller on an appropriate installation stand, remove one section of Koat-A-Roll® from the oven, and insert the special installation nozzle which is adapted to a standard shop air hose. This air nozzle is available from Kastalon. To help the covering slide over the roller, coat the end of the roller with K-Lube. Kastalon offers K-Lube Assembly Lubricant which is specifically formulated for the installation of Koat-A-Roll® and Vinyl-Koat®.
