Vinyl Acetate-vinyl Versatate Copolymer Dispersion (Equivalent EMULTEX or Mowilith or VINNAPAS) Vinyl acetate-vinyl versatate copolymer dispersion developed forformulation of waterborne intumescent coatings FR‑110 is a specially colloid‑stabilized binary copolymer dispersion engineered for formulating waterborne intumescent coatings. FR‑110 delivers controlled char formation with high expansion factor, while preventing char‑layer hardening and brittleness under fire exposure.
