What should be paid attention to when the wheel core is covered with polyurethane?
Matters needing attention when iron core polyuethane coated wheels are used for polyurethane rubber parts:
1. When the polyurethane is encapsulated, there is water on the sprayed surface, and bubbles will be generated when the paint meets water;
2. It dries too fast, and the paint is not popular;
3. When the polyurethane is encapsulated, there is water on the brush during the brushing process, resulting in bubbles;
4. Please take protection from stepping, rain, sun exposure, sharp damage, etc. before being completely dried after construction.
