Levelling Agent HL788 is a powder coating additive designed to improve flow, leveling, and surface uniformity during the curing process.
Levelling Agent HL788 helps reduce common coating defects such as orange peel, craters, fish-eyes, pinholes, and poor wetting, resulting in a smoother and glossier final film.
Levelling Agent HL788's use in epoxy, polyester, hybrid, and polyurethane powder coating systems supports better appearance, improved substrate wetting, and more consistent coating quality.

Levelling Agent HL788 with silica adsorption of polyacrylate flow ping agent, both are suitable for all kinds of thermoplastic and thermosetting powder coating, which can effectively improve the flow of powder coating, increase the clarity and flow flat surface effect.
Levelling Agent HL788 is a powder coating flow and leveling additive used to improve surface smoothness, film uniformity, and final coating appearance.
Levelling Agent HL788 is part of the HL988 / HL788 / HL505 levelling agent series for powder coating systems.
In thermosetting powder coatings, HL788 helps reduce common surface defects such as orange peel, craters, fish-eyes, pinholes, and poor wetting by improving flow during melting and curing.
Levelling Agent HL788 is suitable for epoxy, polyester, epoxy-polyester hybrid, polyurethane, and other powder coating formulations where better gloss, smoother film formation, and more consistent surface quality are required.

Applications of Levelling Agent HL788:
Levelling Agent HL788 is widely used in pure epoxy type, mixed type, pure polyester type (TGIC)/hydroxyl alkyl amide and polyurethane etc.
Various kinds of thermosetting powder coating, as universal flow ping agent.
Levelling Agent HL788 eliminate the phenomenon of fisheye, shrinkage, reduce the film surface tension, improve gloss coating.
Levelling Agent HL788 improve improve wetting of base material, reduce the orange peel.
Levelling Agent HL788 does not contain silicone composition, do not affect coating adhesion.
Levelling Agent HL788 usage for 1.2%-1.6% of the total, are not including wetting promoter, the user can be adjusted according to this formula;
Levelling Agent HL788 is used as a flow and leveling additive in powder coating formulations.
Levelling Agent HL788 is suitable for epoxy, epoxy-polyester hybrid, polyester TGIC/HAA, polyurethane, and other thermosetting powder coating systems.
Levelling Agent HL788 helps reduce surface tension during melting and curing, allowing the coating film to flow more evenly and form a smoother, glossier, and more uniform surface.
Levelling Agent HL788 is mainly used to reduce orange peel, craters, fish-eyes, pinholes, poor wetting, and uneven film formation in decorative and industrial powder coatings.
