990-06 Yellow Jacket is a bright yellow, open weave glass fabric consisting of glass fibre yarn saturated with synthetic resins. The bright yellow colour helps the applicator determine when the fabric is completely embedded in the coating compound, particularly under poor lighting conditions. The glass fibre in this product will not rot, mildew nor “wick” water into the body of the coating material.  990-06 typically is used as a reinforcing membrane incorporated into many types of coatings where superior strength and toughness are required.
