Polyvinyl Butyral (PVB) Resin DM-01
Charateristics:
PVB resins can be divided into different levels according to their molecular weight and degree of acetalization.
Solvent preparation:
1)Low viscosity PVB resin can be dissolved in a variety of organic solvent and mixed solvent, alcohol is the best solvent, esters and ketones are inferior solvent comparing with alcohol, aliphatic hydrocarbon and aromatic hydrocarbon solvents are insoluble, but they can be used as diluents together with alcohol solvent;
2)Solution: lunch agitator stirring solution in slow or medium speed under room temperature proportionally and slowly add PVB powder, could increase the stirring speed after solutiwetting;
3)Viscosity of solution, decomposition velocity depend on the type, temperature and stirring speed of the solution;
4)Low viscosity PVB resin can be processed and used by the general equipment of printing ink and paint
industry
Storage
Under a dry and cool (25 ℃ or less) condition, the product can be stored for at least 12 months if sealed in
original packaging.
