Charateristics:
PVB resins can be divided into different levels according to their molecular weight and degree of acetalization
Recommended Uses:
1)Coating adhesive
2)Ink adhesive;
3)The whiteboard ink adhesive;
4)Textile printing and non-woven adhesive;
specification:
| Volatile content | ≤3.0 |
| Unit | SB-1 |
| Non Volatile content | |
| Butyral content | 70-80 |
Solvent preparation:
1)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 solution wetting;
2)Viscosity of solution, decomposition velocity depend on the type, temperature and stirring speed of the solution;
3)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.
Preventive measures:
during the operation process of dissolving, appropriate take safety measures, and prevent electrostatic.
