Polyvinyl Butyral B-08HX CHANG CHUN GROUP
Technical Data Sheet Effective date: 2015/08/10 Version : 1.0, Page 1/1
Characteristics CCP PVB B-08HX is a polyvinyl butyral resin with a medium solution viscosity. CCP PVB B-08HX is manufactured from the condensation reaction of Polyvinyl Alcohol and n-butyraldehyde. B-08HX is a thermoplastic resin, which is soluble in most organic solvents with excellent film forming capability, strong adhesion to glass, metal, plastic, leather and wood. CCP B-08HX is a white free flowing granule or powder and non-toxic to humans and animals. Specification Item value Unit Remark Butyral content 76 – 82 wt% Hydroxyl content 18.0 – 21.0 wt% Acetyl content ≦2 wt% Solution viscosity was determined in 10% by weight in Viscosity 120 – 180 cps ethanol/toluene = 1/1 at 20°C, using Brookfield viscometer Free Acid ≦0.05 wt% Volatile ≦3 wt% Application Additional Data Typical applications for B-08HX are - wash primer, Specific gravity : 1.05~1.10 paint, ceramic binder, coating and adhesive. Due to Bulk density : 0.25 – 0.40 g/cm³ for powder free hydroxyl groups, B08HX can be used as a Glass transition temperature : ca. 71 °C reactive component or as a co-binder in two-pack Melting Point : 135 – 185°C systems. For example, B08HX can be crosslinked Molecular weight : 52,000 – 62,000 g/mole with phenolic, epoxies, melamine, isocyanate resin. Degree of Polymerization : 800 - 900 Package CCP PVB B-08HX is packed in 10 kg, multi-ply paper bags. Processing Storage & Handling CCP Polyvinyl butyrals are soluble in most organic Keep in a tightly sealed container, stored in a cool, solvents. The viscosity of PVB solution depends on dry, and ventilated area. Under these conditions, the the concentration of resin, temperature of solution product has a shelf life of at least 24 months, and the solvents employed. PVB resin is most beginning with production. soluble in a mixed solvent system such as If the material is kept beyond the recommended shelf ethanol/toluene, methanol/methyl ethyl ketone, etc. life, it is not necessarily expired, but the user should Typically CCP B-08HX is used in solution. The adopt a quality control on the properties relevant to best solvents for CCP B-08HX are alcohols. It the application. The characteristics determined in our dissolves completely in Methanol, Ethanol, pre-release quality control may change during N-Propanol, I-Propanol, N-Butanoll. In Esters and storage, depending on storage conditions, and Ketones, CCP B-08HX is partly soluble or deviating from the specification. insoluble.
