invention may be stored as such for prolonged periods at room temperature without gel formation or any other undesirable changes occurring they may be diluted as required to a suitable concentration and applied by the conventional methods for example spraying or spread coating and heated generally to temperatures in excess of about 260 u00b0 f preferably from about 260 u00b0 f to 290 u00b0 f more preferably from about 260 u00b0 f to 270 u00b0 f in order to cure the coating the compositions may be used as coating agents for primer intermediate or surface coatings for a variety of different substrates the resulting coatings possess excellent adhesion to substrates are uniform and exhibit excellent mechanical and chemical properties and water and solvent resistance especially hardness impact resistance and elasticity the invention is further illustrated but is not intended to be limited by the following examples in which all parts and percentages are by weight unless otherwise specified a composition in accordance with the present invention was made using the ingredients in table 1 1 0 parts of 34 a 34 were mixed with 2 3 parts of 34 b 34 by weight in a separate container using commercially available spray application equipment capable of automatically metering proportions of 34 a 34 and 34 b 34 the composition obtained is shown in table 2 the mixed components are then applied to an object to be painted using standard application techniques known in the art these could include but are not restricted.
