Question 1

What substrate types is PU-3030 suitable for?

Accepted Answer

PU-3030 is designed for flexible and semi-flexible substrates including synthetic leather (PU/PVC), textile fabrics, TPU films, and polyolefin films treated with corona or primer. Its Shore A hardness of 75–85 provides a balance of abrasion resistance and flexibility without cracking on flex substrates.

Question 2

Can PU-3030 be reformulated to reduce DMF content?

Accepted Answer

DMF (dimethylformamide) is a reproductive toxin (SVHC) with strict occupational exposure limits. PU-3030 can be reformulated using MEK/toluene/ethyl acetate blends at slightly reduced solids, or waterborne PU dispersions can serve as the DMF-free alternative.
