POLYFLUO 150 is a unique combination of high density polyethylene and PTFE that has been micronized to a 1.0-2.0 NPIRI grind gauge reading. Due to its extra fine particle size, POLYFLUO 150 can be readily mixed into all ink and coating systems with conventional dispersion equipment. Pre-dispersion or excessive grinding is eliminated using POLYFLUO 150 and most inks and coatings can be readily processed using filtration techniques.
POLYFLUO 150 has been formulated to impart the excellent rub resistance and hardness usually associated with polyethylene, along with the lubricity (slip) provided by PTFE. Each of the components are designed to provide properties for optimum performance when incorporated into printing inks, paints and coatings.
Optimum properties are usually achieved by adding 1-3% by weight. The amount required will vary depending on the type of application and the end use requirements.
POLYFLUO 150 is recommended for use in the following areas: Flexo, gravure, web offset-heat set, sheet fed (quick set), ultra violet and metal decorating printing inks; coil coatings, industrial paints or finishes and all types of overprint varnishes. POLYFLUO 150 is especially effective in improving apparent adhesion and scratch resistance of flexographic and gravure inks on non-porous substrates and in high solids/low energy heat set inks where maximum abrasion resistance is required.
At temperatures above 600°F some polymer fumes may be emitted due to decomposition of the fluorocarbon polymer. Therefore, smoking should not be permitted when working with this material.
