Additives and resins for marine and protective coatings — high film builds, harsh conditions, long protection intervals.
Protective systems work with high film thicknesses and high pigment loadings — zinc-rich primers, micaceous iron oxide intermediates, abrasion-resistant topcoats. The formulation has to release air during airless spraying, stay put on vertical surfaces and wet reliably even when applied on site; every film defect is a future rust spot.
From BYK we carry defoamers and air release agents, wetting and dispersing additives for heavy pigments and rheology additives against sagging; epoxy-compatible resins and binders come from the Synres and Alberdingk programmes.
Typical defects — and where the solution lies
Thick-film system sags on vertical surfaces
Build sag resistance with layered silicates and thixotropic rheology — without losing sprayability. — Rheology additives →
Microfoam during airless spraying
Air-release additives for high-viscosity, highly filled systems — every remaining bubble is a future defect. — Defoamers →
