DOWSIL™ 401LS Additive

  • Overview

    Leveling and Slip Additive for coating and ink applications

    Highly Effective Flow and Leveling

    Lowers Coefficient of Friction

    Superior Compatibility for Clear Coats

    Power Up Your Coatings

    Dow Consumer Solutions introduces an innovative family of silicone slip and leveling agents for solventborne, waterborne and radiation curable wood, furniture and plastic coatings, inks and overprint varnishes:

    • DOWSIL™ 205SL Additive
    • DOWSIL™ 204SL Additive
    • DOWSIL™ 401LS Additive

    Are you looking to differentiate your formulations by offering systems that provide a pleasing hand feel and improved flow and leveling performance, but can’t find additives that don’t affect recoatability or foam stabilization? Do you have a wide range of resin systems targeting many different applications and are having difficulty finding just the right additive for each system?

    Dow Consumer Solutions' innovative family of slip and leveling agents allows you to identify tailored solutions and fine-tune your solventborne, waterborne and radiation curable coating, ink and OPV formulations for optimum performance on wood, furniture and plastic substrates.

    Advantages of Dow Consumer Solutions™ Brand Slip and Leveling Additives

    • Can be used in solventborne, waterborne and radiation cured paints, coatings, inks and overprint varnishes 
    • Effective on wood, furniture and plastic substrates 
    • Lower the coefficient of friction 
    • Highly effective flow and leveling properties 
    • Good recoatability 
    • Effective at low addition levels 
    • Compliant with European legislation for indirect food contact (Swiss Ordinance RS 817.023.21 Annex 6, Part B) 
    • BTX-free 
    • Enable minimization of raw material portfolio 

    DOWSIL 401LS Additive brings excellent wetting and leveling properties, which can positively impact film appearance. And it achieves these results at use levels as low as 0.075% based on total formulation, further increasing its cost effectiveness. Where some additives impact coating clarity (due to incompatibility) and recoatability, DOWSIL 401LS Additive has no impact on these properties.

    Key Features of Specific Slip and Leveling Additives

    • DOWSIL 205SL Additive is a multipurpose silicone additive offering top performance in leveling, slip and hand feel, combined with excellent defoaming properties. 
    • DOWSIL 204SL Additive provides excellent slip, superior hand feel, better recoatability and improved clarity with comparable leveling speed, particularly for radiation curable formulations. 
    • DOWSIL 401LS Additive provides excellent wetting and leveling in solventborne formulations at use levels as low as 0.075% and without affecting clarity or recoatability. 
    • DOWSIL™ 57 Additive and DOWSIL™ 402LS Additive complete the family of additives. Both are standard Dow Consumer Solutions products for leveling. 

    While each individual product has primary properties that deliver key performance benefits in a formulation, the final choice of additive should also depend on its secondary attributes. Together these characteristics will reflect the exact combination of properties required for a given application.
