Abstract
A clathrate of 1-methylcyclopropene with α-cyclodextrin, obtained as a solid particulate product, is modified by comminuting, classifying, or both to obtain a modified particulate. When subjected to identical atmospheric disgorgement conditions of humidity and temperature, identical masses of the modified and unmodified particulates exhibit different rates of 1-methylcyclopropene disgorgement. Specifically, we have found that a smaller mean particle size is inversely related to a greater rate of 1-methylcyclopropene release.
Claims11
A coated substrate comprising a coating affixed to a substrate surface, the coating comprising a mixture of:
- a particulate consisting essentially of at least 85 wt % of a 1- methylcyclopropene clathrate of α-cyclodextrin and 0-15 wt % α-cyclodextrin, the particulate having a mean particle size between 3 μm and 15 μm, between 1 μm and 10 μm, or between 10 μm and 20 μm as determined by a volume-based method;
- and
- a polymer.
