  Transparent interlayers( Sinopont adhesive, SPA )
 

Sinopont series of transparent interlayersSPAhave excellent adhesion to glass and can entirely integrate with glass. The products have wonderful weathering resistance bearing awful environment from -40 to 80. SPA has the great elasticitythat can absorb most of the power of impact devoting to minimize the shock and is the well buffer to keep voice outside. Special designed interlayers have the excellent toughness and perfect adhesion that can bond the glass tightly preventing the splash of glass particle.

1Ultra-violet transmittance typeSPA-U

SinopontSPA-U interlayer has excellent transmittance of wide range of wavelengths.SPA-Ucan combined with low iron glass, which screens the harmful light of wavelength less than 300nm and remains the light of germicidal irradiation ranged 300~400nm wavelengths. It can almost obtain the complete spectra effect. SPA-U is suitable for special requirement outside, such as PV module, glasshouse, greenhouse, artificial panoramic room, etc.

2UV block typeSPA-Visible, SPA-V

SinopontSPA-Vinterlayer has excellent UV block capability. SPA-V can screen UV light of less than 380nm wavelength and pass the visible and infrared spectra. Visible light ensure the fine illumination. Infrared spectra have almost half of heat in spectra so that can provide well heating. SPA-V can avoid the harm of UV light, such as UV aging, UV pathology. SPA-V is suitable for people and environment tending to allergy.

3Heat free typeSPA-Heat Free, SPA-HF

SinopontSPA-HFinterlayer has excellent UV block, infrared spectra block and part of visible light screen. SPA-HF can screen most heat of spectra and remain the certain visible light enough to illumination. SPA-HF is suitable for building or space needing illumination, such as great railway station, airport, car, office, etc
