ABRASION-RESISTANT COATING

摘要

Radiation-curable abrasion-resistant coatings are formulated from (A) multifunctional acrylate polymers and (B) a silane-based composition. The multifunctional acrylate polymers are selected from the group consisting of polyester acrylates, epoxy acrylates, urethane acrylates and admixtures of the aforesaid. The silane-based composition is a combination of: a Michael adduct formed from a multifunctional acrylate monomer and an aminofunctional silane; and colloidal silica. The composition of the invention can be varied within the claimed compositional limits to provide materials for floor coatings that exhibit various properties including stain resistance, adhesion to a specific substrate and flexibility.
