Application
- For Automotive and architectural glass
Laminated glass, commonly used in the automotive and architectural fields, comprises a protective interlayer, usually polyvinyl butyral, bonded between two panels of glass. The bonding process takes place under heat and pressure. When laminated under these conditions, the PVB interlayer becomes optically clear and binds the two panes of glass together. Once sealed together, the glass "sandwich" (i.e., laminate) behaves as a single unit and looks like normal glass. The polymer interlayer of PVB is tough and ductile, so brittle cracks will not pass from one side of the laminate to the other.
- Colors PVB for tinted glass
Band Colors PVB interlayer can be used for the blue or green "shade band" at the top edge of many automobile windshields. Full Colors PVB interlayer can also be used in different colors for architectural laminated glass manufacture ranging from Bronze, Gray, Green, Brown, White and many more.
- Solar modules
PVB has gained acceptance among manufacturers of photovoltaic thin film solar modules. PVB and a second sheet of glass (called back glass) are then placed directly on the circuit. The lamination of this sandwich encapsulates the circuit, protecting it from the environment. Current is extracted from the module at a sealed terminal box that is attached to the circuit through a hole in the back glass.

Product Description
1.Excellent adhesion to metals, plastics, glass, ceramics, wood, concentrate, leather etc.
2.With very large surface area combined with low molecular weight, product undergoes into solution under mild agitation in a very short time to offer clear transport solution with minimum loss of solvent.
3.Product is soluble in low cost environment friendly solvents like alcohols, glycol ethers &has ability to accept eater, ketones etc.
4.Excellent film formation property. Film being clear, transparent, odourfree and tasteless
5.excellent pigment wetting in non-aqueous medium
6.Excellent compatibility with other film forming resins like N.C., Epoxy alkyds, phenolics, cellulosics etc.
7.Free hydroxyl groups present in it are chemically reactive and undergo reactions with phenolics, epoxies, isocyanides, melamine aldehyde resins etc.
8.Being lowest molecular weight resin of HAOCHENG series offers excellent flexibility. Product also shows good adhesion resistance, heat resistance, resistance to water and wide range of other chemicals.
9.PVB is a thermoplastic resin with low softening temperature and hence shows good heat sealing properties. Thermo plasticity can be reduced or eliminated completely by cross linking reaction involving free hydroxyl groups.
Two layers of packaging, lined with plastic bag, plastic woven bag(lined with a layer of plastic film), the net weight of 12.5kg or 500kg, and according to customers requirement packing.
