Zusammenfassung:A curable polymer composition for use in providing a dimensionally stable coating comprises a semi-interpenetrating polymer network. The semi-interpenetrating polymer network includes a reactive polymer component, cross-linking agent, and non-reactive polymer component. The non-reactive polymer component has a molecular weight of about 7,000-30,000, and preferably about 15,000. In preferred embodiments, the reactive polymer has a molecular weight of about 30,000-200,000, and preferably about 40,000-60,000. Spacecoat compositions made with formulations described, exhibit good long-term stability, and resistance to failure upon embossing of a substrate to which the retroreflective sheeting is applied.
