  • Radiation curable drumhead membrane
    Patent number: 9190039
    Abstract: A drumhead and a method for coating a drumhead membrane comprising applying a coating having cross linkable polymeric material to the membrane and applying energy to cross link the polymeric material and thereby permanently adhere the material to the membrane as a play surface. The cross-linking not only hardens the coating to improve durability, but also improves the adhesion of the coating to the base film. Actinically cured coatings can completely harden in a matter of 3 to 5 seconds, with UV cured inks being especially desirable.
