Trim Fluid is a general-purpose, solvent-based, static dissipative coating liquid which can be used on a variety of plastic substrate materials to make the surface of the plastic electro-conductive in the static dissipative range of surface resistivities. It is normally used as a touch-up coating on cut edges and machined surfaces. This touch-up coating prevents static charge build-up on these edges and surfaces and it provides electrical continuity across the cut or machined area. Since trim fluid is a solvent (alcohol) based coating, it can relieve stresses induced in plastic sheet edges that have been exposed to applications that excessively heat the plastic, such as flame polishing and laser cutting. On occasion, this can cause crazing or cracking of the cut edges. To avoid this, plastic which has been exposed to stress-inducing procedures should be annealed to remove the stresses before coating.
Trim Fluid is designed to be used only as a touch-up coating on static dissipative plastic sheet products and not large areas. Other uses are not recommended. Trim Fluid is an air dry, non-crosslinked coating. It can provide continuity from front to back surfaces of plastic sheets by forming an electro-conductive bridge across the edge of the sheet. Trim Fluid is also used on glue lines in fabricated items to provide electrical continuity across the glue joints.
Although Trim Fluid coating adheres well to non-contaminated plastic surfaces and resists removal with mild soap and water solutions, it can be removed with alcohol and other solvents. Consequently, care should be taken to avoid contact with such materials during cleaning to maintain the integrity of the coating.
Coverage varies widely depending on the nature of the surface being coated. Ideal coverage on very smooth, flat surfaces is approximately 5 square feet per ounce of Trim Fluid liquid.
