MG Chemicals 4354-4L - Thinner 4, Slow-drying, Blush Resistant, 1 Gal Can, 4354 Series
The 4354 Thinner 4 is a slower-drying thinner for use with MG Chemical’s urethane and acrylic conformal products. The thinner has excellent solvent strength, making it a good oil and grease remover. It has very low water solubility, so it is unlikely to absorb water and create a blush. Its drying speed is slow enough to promote excellent leveling, but it is fast enough to accommodate a reasonable assembly line speed.
The 4354 makes a good choice for spray application.
