The polyurea products can usually be provided in either, but the aliphatic is about twice the price for most formulas (aromatic is standard). Only significant difference is for white with respect to color stability. If applying polyurea in white, we recommend top coating with our Ultrathane product in white for lasting color stability.
Most polyurea applications do not significantly benefit from the extra cost of an aliphatic coating when it comes to our products. If eventual color fading is a critical issue and you do not want to topcoat, we also have cartridge products available with additional color fast additives for only a few dollars more per cartridge.
