Abstract
Disclosed are methods of protecting porous substrates and/or increasing the peel-resistance of coatings and stains for porous substrates. The methods may include providing a stain or coating comprising a microencapsulated self-healing material; and applying the stain or coating to a porous substrate. Damage to the stain or coating may release the self-healing material at a site of damage, such as a crack or scratch in the stain or coating. The self-healing material may be a polymeric precursor, an unsaturated polyester resin or alkyd, a fatty acid-based natural oil or derivative thereof, or a cross-linkable silane or siloxane monomer or resin. The microencapsulated self-healing material may include a microcapsule having a shell wall that includes a thermosetting polymer or a thermoplastic polymer; the thermosetting polymer may include urea-formaldehyde, melamine formaldehyde, polyurethane, polyurea, or polyacrylate; and the thermoplastic polymer comprises poly(methyl methacrylate), poly(lactic acid), or poly(glycolic acid).
