Leveling Agents

Based on 59 products - Last update on the Jun 26, 2025

Leveling agents are typically clear, low-viscosity liquids that are added to plastics to enhance surface smoothness and uniformity. They function by reducing surface tension, which allows the coating or plastic to spread more evenly, eliminating defects such as brush marks, orange peel, and craters. Key features of leveling agents include their ability to improve gloss, adhesion, and overall aesthetic appeal of the final product. Used in automotive coatings, industrial paints, and plastic films. 

Alternatives to leveling agents include flow modifiers and surface-active agents. Sub-types include silicone-based, acrylate-based, and fluorocarbon-based agents.

BYK® -354

by BYK

BYK® -354 by BYK is a polyacrylate-based, surface additive. It is used as an anti-cratering & leveling additive, increases gloss and also has a deaerating effect as a result of its high molecular weight and non-polar structure. This thermally stable additive only reduces surface tension slightly. <br> <ul style="padding-left: 40px;"> <li>It is recommended for all ambient curing resin systems such as unsaturated polyester resins and epoxy resins. </li> <li>The recommended level is 0.1-1.5% additive (as supplied) based upon total formulation. </li> <li>It is listed in EINECS, TSCA, DSL, AICS, PICCS, IECSC, ENCS, NZIoC and ECSI. </li> <li>It is in line with EU Directive 2011/65/EC (RoHS 2), EU Directive 2002/96/EC (WEEE), EU Directive 94/62/EC (Packaging Waste) and CONEG Toxics in Packaging. </li> <li>It complies with REACH Regulation (EC) No 1907/2006. </li> <li>The shelf life of BYK®-354 is 60 months. </li></ul>

GEROPON® 99

by Syensqo

GEROPON® 99 by Syensqo is an excellent anionic wetting, rewetting and leveling agent. It possesses good emulsifying and dispersing properties. GEROPON® 99 has very low dynamic surface tension, and migrates to interfaces very rapidly. It is used to reduce surface tension and to increase absorbency and penetration. It is used in polyolefin films, acrylic & modified acrylic plastics, semi-rigid and rigid, perfluorocarbon resins, polyethylene phthalate polymers and polysulfide polymer-polyepoxy resins. It has low-VOC, improves system stability and durability. It is listed in the FDA.
