STRIPPABLE COATINGS

摘要

Strippable coatings have been used in industry maintenance and production process applications for more than 30 years, but it has only been in the past few years that environmental laws and worker-safety rules have made water-based strippables a viable alternative to their solvent-based counterparts. How solvent- and water-based strippables compare in composition and performance determines which is preferred for the application in question. Solvent-based solutions and water-based emulsions are formulated to adhere to substrates, and their adhesion is checked as a standard quality-control procedure. Solvent-based solution and water-based emulsion strippables differ from their conventional counterparts in that the strippables contain release agents that limit the adhesion they have to different substrates. The role that the release agents play in controlling the adhesion of the strippables to their substrates is governed by the performance criteria of the application.
