Adhesives and Epoxies Q&A
-
Does anyone supply an ISO/FDA–approved acrylated urethane adhesive that cures to a green color (or any color other than clear)? Are there any dyes that can be added to a clear acrylated urethane adhesive that will meet ISO/FDA requirements and not change the properties of the adhesive?Answered November 30th, 2010 by Expert:Colored light-curable acrylated urethane adhesives are usually custom-made and therefore hard to find. In order to find a product that will meet your specific needs (colored, medical grade, adhesion to specific substrates), you should contact the adhesive supplier of your choice.
In general, it is possible to add dyes to acrylated urethanes and to achieve ISO/FDA approval. Typically, each formulation is tested to ensure full compliance. The cured properties are usually not impacted; the only area of concern is the ability to achieve a full cure, since some colors can inhibit the light-curing process.
