AcrylLacke

AcrylLacke are coating systems based on acrylic resins that form a hard, protective film when dried or cured. They are used as clear or pigmented finishes on a range of substrates, including wood, metal and certain plastics. The term covers solvent-borne acrylic lacquers as well as waterborne variants, and includes both single-component and multi-component formulations that may incorporate crosslinkers.

The composition of AcrylLacke typically centers on acrylic polymers, such as polyacrylates or copolymers, combined with additives, plasticizers, UV stabilizers and, in some systems, crosslinkers like melamine- or isocyanate-based agents. The vehicle can be solvent-based or water-based, enabling film formation through solvent evaporation or water dispersion. Some formulations also include pigments for color and opacity.

Key properties of AcrylLacke include high gloss, good clarity and relatively rapid drying. They often provide strong adhesion to diverse substrates and can be formulated for strong chemical and light resistance. Solvent-based versions usually offer higher durability but higher VOC emissions, while waterborne variants reduce VOCs but may require different surface preparation and curing conditions. Outdoor durability depends on the formulation and the inclusion of UV stabilizers, and some lacquers may yellow or degrade without appropriate protection.

Applications of AcrylLacke span automotive finishes, furniture and interior wood coatings, musical instruments, and protective coatings for plastics. They are typically applied by spraying, though brushing or dipping can be used for certain products. Finishes may be clear coats or pigmented colors and often require sanding and polishing as part of the finishing process, particularly in automotive or high-gloss applications.

Safety and environmental considerations include the handling of solvent-based formulations and VOC emissions. Regulatory trends favor waterborne, low-VOC or VOC-free AcrylLacke and proper ventilation, storage, and personal protective equipment.
