A method for preparing hydrophilic pressure sensitive adhesive (PSA) compositions is provided, wherein the method enables preparation of adhesives having a particular, optimized degree of adhesion. That is, the hydrophilic PSA is comprised of a hydrophilic polymer and a complementary short-chain plasticizing agent, wherein the hydrophilic polymer and plasticizing agent are capable of hydrogen bonding or electrostatic bonding to each other and are present in a ratio that optimizes key characteristics of the adhesive composition, such as adhesive strength, cohesive strength and hydrophilicity. The adhesive is useful in a wide variety of contexts, e.g., as a biomedical adhesive for application to the skin or other body surface, and as such finds utility in the areas of drug delivery systems (e.g., topical, transdermal, transmucosal, iontophoretic), medical skin coverings and wound healing products and biomedical electrodes.

The method of making the woodpecker deterrent in accordance with claim 5 including the step of mixing said woodpecker deterrent with an epoxy resin and an epoxy hardener for coating onto a wood surface. 7. The method of making the woodpecker deterrent in accordance with claim 6 in which the step of mixing said Isophorone with said heated wax and said thickener includes mixing with a flocculated silica thickener. 8. The method of making the woodpecker deterrent in accordance with claim 7 in which the step of mixing said Isophorone with said heated wax and said thickener includes mixing with a clay thickener. 9. The method of making the woodpecker deterrent in accordance with claim 5 including the step of mixing in an acrylic resin to the Isophorone and the heated wax and the thickener mixture. 10. The method of making the woodpecker deterrent in accordance with claim 9 in which the step of drying includes vacuum drying said mixture of said Isophorone, said heated wax and said thickener with said ceramic pellets. 11. A woodpecker deterrent composition comprising: Isophorone; heated wax; clay thickener; acrylic resin; ceramic pellets; and a polymer resin blended to form a wood coating material which deters woodpecker damage to wood. , 514/384; US-4751225, 19880600, Nishida et al., 514/277; US-4782174, 19881100, Fuchs et al., 558/354; US-4798837, 19890100, Drabek et al., 514/594; US-4833151, 19890500, Wellinga et al., 514/344; US-4843068, 19890600, Hamaguchi et al., 514/063; US-4845097, 19890700, Matsumoto et al., 514/234.2; US-4879292, 19891100, Nishida et al., 514/241; US-4883806, 19891100, Martel et al., 514/417; US-4918086, 19900400, Gsell, 514/351; US-4918088, 19900400, Gsell, 514/357; US-4920135, 19900400, Wellinga et al., 514/344; US-4931439, 19900600, Kristinsson, 514/242; US-4948798, 19900800, Gsell, 514/275; US-4950668, 19900800, Okada et al., 514/232.2; US-4962126, 19901000, Drabek, 514/587; US-4963572, 19901000, Gsell, 514/357; US-4963574, 19901000, Bachmann et al., 514/357; US-4970222, 19901100, Nishida et al., 514/369; US-4970330, 19901100, Huff, 558/407; US-4980506, 19901200, Drabek et al., 564/442; US-4996325, 19910200, Kristinsson, 548/132; US-5004822, 19910400, Elliott et al., 556/115; US-5010098, 19910400, Brown et al., 514/426; US-5034404, 19910700, Uneme et al., 514/365; US-5049571, 19910900, Gsell, 514/345; US-5063236, 19911100, Gsell, 514/318; US-5107017, 19920400, Drabek et al., 560/358; US-5110986, 19920500, Kelly, 564/149; US-5142064, 19920800, Wellinga et al., 549/404; US-5153224, 19921000, Drabek et al., 574/594; US-5175301, 19921200, Minamida et al., 546/272; US-5192778, 19930300, Kodaka et al., 514/341; US-5214152, 19930500, Minamida et al., 548/181; US-5232940, 19930800, Hatton et al., 514/407; US-5245071, 19930900, Wellinga et al., 560/027; US-5256679, 19931000, Minamida et al., 514/357; US-5262383, 19931100, Fischer et al., 504/195; US-5264584, 19931100, Kodaka et al., 548/332.5; US-5310938, 19940500, Brown et al., 548/557; US-5319092, 19940600, Jacobson et al., 548/264.4; US-5342958, 19940800, Wellinga et al., 548/317.5; US-5367093, 19941100, Dekeyser et al., 560/027; US-5411963, 19950500, Dreikorn et al., 514/259; US-5434181, 19950700, Kodaka et al., 514/471; US-5438123, 19950800, Dekeyser et al., 534/885; US-5455263, 19951000, Doscher et al., 514/422; US-5462938, 19951000, Annus et al., 514/229.8; US-5470984, 19951100, Jacobson et al., 548/264.4; US-5478855, 19951200, Suzuki et al., 514/374; US-5489603, 19960200, Uneme et al., 514/365; US-5532365, 19960700, Kodaka et al., 544/212; US-5536746, 19960700, Dekeyser et al., 514/468; US-5547974, 19960800, Hatton et al., 514/406; US-5595915, 19970100, Geysen, 436/518; US-5608077, 19970300, Hatton et al., 548/365.1; US-5614527, 19970300, Kinoshita et al., 514/256; US-5633375, 19970500, Uneme et al., 544/336; US-5696256, 19971200, Kando et al., 540/463; US-5708170, 1998
