7390 Polyacrylate Levelling Agent is a specialized, silicone-free surface additive engineered to optimize the topographical uniformity of high-performance coatings. Functioning primarily through th…
Elimination of Surface Defects: Effectively prevents cratering, fish-eyes, and crawling by balancing surface tension across the film.
Superior Recoatability: Silicone-free formulation ensures excellent intercoat adhesion and zero risk of silicone contamination in sensitive paint shops.
Enhanced Optical Properties: Significantly improves Distinctness of Image (DOI) and gloss by promoting a perfectly smooth, level surface.
Air Release Properties: Assists in de-aeration, reducing the risk of pinholes during fast-curing or high-build application processes.
Substrate Wetting: Enhances the ability of the coating to wet low-energy substrates, ensuring a uniform and continuous film layer.
规格
