Performance by design: abrasion and scratch resistance UV/EB curable sealers and topcoats
An optimized UV cured topcoat and a sealer combining good scratch and abrasion resistance for wood was developed. A combination of screening, ladder and experimental design technique was used. First 12 urethane acrylate oligomers were screened for abrasion and scratch resistance and the four best oligomers were chosen for a ladder study incorporating additives like reactive waxes, silica and alumina. Using statistical design of experiments, an optimized sealer and topcoat formulation was uncovered. Results of these experiments showed that a combination of a topcoat consisting of an urethane acrylate oligomer, reactive wax and non reactive silica cured on a sealer (polyurethane based sealer) gave very good combined abrasion and scratch resistance properties.
