Thinnercoated

Thinnercoated is a term used in coatings technology to describe a coating layer that is deliberately applied thinner than standard reference coatings. The concept covers coatings whose dry film thickness is typically in the low micrometer range, achieved by solvent dilution, using low-solids or fast-drying formulations, or applying fewer coats. Thinnercoated finishes are common in decorative wood finishes, electronics packaging, and automotive repair where weight, cure time, or surface smoothness are critical.

Application and measurement: Techniques to achieve thinner coatings include diluting the coating with compatible solvents, using high-solids formulations but applying a single thin coat, or using spray or dip processes tuned for low film thickness. Dry film thickness is measured with magnetic inductive methods, eddy current, or ultrasonic instruments; standard practice in many industries relies on ISO or ASTM procedures for thickness determination. Typical dry film thickness for thinnercoated finishes ranges from about 5 to 25 micrometers, compared with 20 to 100 micrometers for conventional protective coatings, though values vary by product and substrate.

Performance and trade-offs: The main advantages are material savings, reduced weight, faster curing, and smoother surface. Limitations include decreased barrier protection against moisture and chemicals, reduced abrasion resistance, and greater sensitivity to substrate preparation and environmental conditions. Performance depends on formulation compatibility, substrate roughness, and application method.

Industry context: Thinnercoated approaches are selected when project constraints prioritize speed and economy over maximum durability. They require careful surface preparation and quality control to avoid pinholes or thickness variability. The term is not tied to a single product or standard, and does not replace thicker, protective coatings where required.
