Acrylic Sealant (or Sealer)
Acrylic Sealant is an acrylic-based finish (or varnish) usually applied over cured polymer clay. Acrylic sealants are available in gloss, satin, or matte finish. Most of them (but not all) are water-resistant and/or UV resistant.
Please refer to my tutorial about finishing techniques for polymer clay to learn more about different types of acrylic sealants and how to work with them.
