MG Chemicals 4354 Thinner 4

The 4354 Thinner 4 is a slower drying thinner for use with the MG Chemical’s urethane and acrylic conformal products. The thinner as 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 blush. Its drying speed is slow enough to promote excellent leveling, but it is fast enough to accommodate a reasonable assembly line speed.
