Abstract
An additive that is incorporated into a thermoplastic acrylic pre-polymer formulation to render the polymer surface hydrophilic with easy cleanability and also making the surface antimicrobial. The additive is a hydrophilic reactive additive or (“HRA”), is incorporated with the other acrylic formulation components and polymerized into the acrylic polymer backbone. This reaction ensures that there will be no loss of hydrophilicity after repeated contact of the easy to clean acrylic sheet with water, as is typically happens with most sanitary ware products.
