About Coated Fabrics

- Feb 28, 2019-

Coated fabrics consist of a standard uncoated fabric with an opaque rubber backing applied to the rear of the fabric to provide improved light absorption. To create a coated fabric, a liquefied rubber polymer is applied in a single coat to an uncoated fabric and subsequently fused dry by means of a heated roller, in much the same way that a laser printer applies toner to a sheet of paper before fusing it dry. A fabric that has been through the coating process once is considered a "1-pass-coated" fabric, anecdotally referred to as "dim-out" or "blackout" because of the fabric's ability to absorb approximately 50-70% of a direct light source. To improve the light absorption of a fabric it is possible to re-coat a fabric up to a maximum of "3-pass-coated", which is considered sufficient to block out 100% of a direct light source, hence such fabrics are referred to as "blockout-coated".
