Products & Materials第 40 / 100 题
What is the purpose of adding a small, manufacturer-recommended amount of the correct thinner to paint for spraying?
a.To reduce viscosity so the paint atomizes and flows properly through the sprayer
b.To increase the VOC limit allowed by law
c.To make the paint dry slower on purpose in all cases
d.To change the color of the paint
解析
Thinning to the manufacturer's recommendation lowers viscosity so the material atomizes and sprays evenly, reducing clogging and improving finish. Over-thinning causes runs and reduced film build, and any thinning must stay within VOC limits. Always follow the product data sheet for the correct solvent and amount.
