Application
Photosensitive emulsion adhesive
PVA 26 has high resolution, high viscosity, water development, mechanical strength and solvent resistance. So it widely used in photosensitive emulsions for screen printing, PCB manufacturing. PVA BP 26 has film-former and colloid carrers functions.
Suspending agent
PVA BP04 is used as a protective colloid for the polymerisation of PVAC. Prevents polymer particles from coalescing (sticking together) during polymerization. And used in suspension polymerization (e.g., for PVC) to disperse monomer droplets in water.
