TP1174 Cross-linker (Similar to Powder Link1174)
Description
The TP1174 cross-linker can be cross-linked in the presence of a catalyst with polymers containing functional groups such as resins containing hydroxyl, carboxyl, amide, thiol or amino functional groups. Its advantages are: excellent hardness and flexibility,excellent solvent resistance, excellent weather resistance, low temperature/fast cure potential, and low usage.
