Asian Paints Woodtech PU Thinner

Description

Asian Paints WoodTech PU Thinner is the solvent made for diluting Asian Paints polyurethane wood finishes to the correct application viscosity. It is a matched component of the WoodTech PU system, not a general-purpose thinner.

That distinction is the whole point of buying it. A PU finish cures by chemical reaction, and the solvent you add takes part in how that reaction proceeds and how the film forms. Use the thinner formulated for the system and you get better levelling, better film formation and faster drying — the film flows out smoothly rather than holding brush marks, and it sets as a continuous coat. Use a cheap general thinner or an NC thinner instead and the same PU finish can bloom, cure poorly, or fail to adhere, which means sanding an expensive coating back off and starting again.

Thinning is not optional on most PU applications either. Straight from the tin a PU finish is usually too viscous to spray, and too heavy to brush without marks. The data sheet for your specific finish gives the correct ratio — follow that, not a rule of thumb, because over-thinning reduces build and film strength just as surely as under-thinning causes runs and brush drag.
