WILT-PRUF® is a natural product derived from the resin of the pine tree which we call a polyterpene polymer or more specifically a beta-pinene polymer which is a film forming short chain polymer component. When the product is sprayed on plant surfaces, the water evaporates leaving a soft, flexible film which degrades one molecular layer at a time when exposed to air and light. The film immediately starts a polymerization into a longer chain, higher weight molecule. However, the entire thickness of the film does not polymerize at the same rate. Only the surface molecular layer is going through rapid polymerization. The molecular layer of the film that is attached and sticking to the leaf is staying a low weight, soft, sticky substance. The film slowly weathers away through this polymerization mode where the top layer fully polymerizes becoming a solid material. It powders away in microscopic flakes which are either washed or blown away, as the rest of the layers go through the same process until the entire film is weathered away. This normally takes about two months under hot, summer conditions and four to six months under cold weather conditions.
