Abstract
This invention concerns a composition useful for preparing latex loam. The composition includes a latex and a polynitrile oxide such as 2, 4, 6-triethylbenzene-1, 3-dintrile oxide, or a latex and an epoxy silane, or a latex and a mixture of the two crosslinkers. The composition may also contain additional components, including fillers, surfactants, cell detackifiers, froth stabilizers, froth boosters, viscosity reducers, compounds to improve resilience and antioxidants. The composition is particularly useful in the manufacture of flooring, wall covering, shoe lining and non-woven materials.
