Overview
PolyCoat RLS-40 is a mineral-free, low-foaming, low dusting product that performs well on a wide range of stocks. The product’s small and uniform particle size helps to speed the incorporation of the coating into the compound upon further processing. This environmentally friendly calcium stearate-based product contains no zinc, alpha quartz, or SARA-reportable compounds. PolyCoat RLS-40 imparts a durable, fast-drying, semi-transparent coating that will not build up at the die head of the extruder. Treated articles can be compression molded.
Typical Properties Odor & Appearance:Mild, White Slurry Specific Gravity:0.95 – 1.1 pH of Concentrate:7.5 – 8.3 Average Solids (%):35 Concentrate Stability:Stable
Applications
Universal choice for slab, extrusion, Barwell preforms, molded articles, and innerliner compounds. Flexible coating helps prevent cold-flow sticking of soft, low Mooney compounds such as natural rubber, nitrile, n-butadiene, and silicone rubber compounds. Semi-transparent, non-yellowing anti-tack coating is ideal for use on colored rubber compounds or anywhere a white residue on the surface of the compounded rubber is not desired. The coating imparted by PolyCoat RLS-40 has not demonstrated any detrimental effects on the compound’s physical properties.
