Overview
Polyvinyl Butyral（PVB for short） is the product of acid catalysis of polyvinyl alcohol and butyraldehyde. Because PVB molecules contain long branched chains, they have good compliance, low glass transition temperature, and high tensile strength and impact strength. PVB has excellent transparency, good solubility, good light resistance, water resistance, heat resistance, cold resistance and film formation. It has high adhesion to materials such as glass and metal (especially aluminum). Therefore, it has been widely used in the manufacture of laminated safety glass, adhesives, ceramic paper, aluminum foil, electrical materials, FRP products, fabric treatment agents and other fields, and has become an indispensable synthetic resin material.
General properties:
The coating film of polyvinyl butyral (PVB) resin has good water resistance, alkali resistance and oil resistance (resistant to aliphatic, mineral, animal and vegetable oils, but not grate oil). Because PVB contains high hydroxyl. It is a base and has good dispersion of pigments, so it is widely used in printing inks and coatings. In addition, its chemical structure. It also contains hydrophobic acetal groups and acetate groups as well as hydrophilic hydroxyl groups, so PVB is compatible with glass, metal, plastic, leather and wood all have good adhesion.
The appearance of polyvinyl butyral (PVB) resin is white spherical porosity particles or powder, and its specific gravity is 1:1; but the filling density is only 0.20~0.35g/ml.
Product name: Polyvinyl Butyral SD-3
CAS: 63148-65-2
Applications:
PVB is widely used in adhesive safety glass interlayers, rust primers, baking paints, wood paints, printing inks, electronic ceramics and printed circuit board adhesives, metal-to-metal, metal-to-plastic adhesives, hot-melt adhesive modifiers, textile iron-dimensional waterproof processing, etc. New applications in various industries are constantly being developed.
Storage:
PVB should be stored in a dry and cool place and avoid direct sunlight, and PVB should be stored to avoid heavy pressure. As long as PVB is not in direct contact with water, it can be stored for two years without affecting its quality.
