Definitions

  • a first binder composition (also referred to as a precursor binder) is applied to a nonwoven mat to form a precursor mat, followed by application of a second binder composition (also referred to as a coating binder), wherein the resin that forms the first binder composition a thermoset polymer and the second binder resin comprises a thermoplastic polymer.
  • thermoplastic material refers to resins or binders that, after curing, become pliable or moldable when heated above a certain temperature.
  • Suitable thermoplastic resins for use according to the general inventive concepts include those having a glass transition temperature of -30 °C to 40 °C. Examples of suitable resins include: Acronal NX 4569, Acronal NX 4787, Acronal NX4612, Acronal NX 3587 and Acronal 4250 from BASF; Rhoplex NW-1845K from Dow Chemical; DUR-O-SET ELITE 22 and DUR-O-SET E-646 Emulsion from Celanese.
  • the thermoplastic material provides the softness needed for flexible mats.
  • Gurley stiffness values decrease along with Tg of the impregnation resins. This is an important feature. By adjusting the impregnation formulation by varying the Tg of resins, the stiffness of impregnated non-woven veils can be tuned (from 810 to 1625 mgf). Tensile strengths for sample 6 to sample 9 are all higher than sample 5 (precursor non-woven mat with Dow 2 - TS ACR) due to impregnation resins. This suggests that impregnated non-woven veils can be adjusted to designed range of Gurley stiffness and tensile strength by changing types and add-on weights of thermoplastic resins.
