Automotive windshield

Aliphatic isocyanates have a small but growing market application in thermoplastic polyurethanes (TPU). Medical appflcafions include wound dressings, catheters, implant devices, and blood bags. A security glass system using light-stable TPU as an inner layer is under evaluation for shatterproof automotive windshield appflcafions. 

Malonates can also be used as blocking agents in the formulation of one-part urethanes. These systems, curable by moisture, are used, for example, for automotive windshield gla2ing (53) (see Urethane polymers). 

Water-soluble polymers eomprise a major elass of polymerie materials and are used in a wide variety of applieations. Synthetie water-soluble polymers inelude poly(vinyl aleohol), poly(aerylamide), poly(aerylie aeid), poly(ethylene oxide), poly(vinyl pyrrolidone), eellulosies, and many eopolymers of these types. Their end uses are quite varied and their applieations depend mainly on their viseosify-ing, rheologieal, and surfaee-aetive properties (1). For example, poly (vinyl aleohol) is used in adhesives, fibers, textile and paper sizing, paekaging, as a stabilizer for emulsion polymerization, and as a preeursor for the manufaeture of poly(vinyl butyral), whieh is used in automotive windshields. Poly(vinyl aleohol) is also the world s largest volume, eommodity, water-soluble polymer. 

Screen printing of UV inks is being done over paper, metal, films, foils, plastics, and PVC. Radiation curable materials are being used as vehicles for ceramic inks that are screened onto automotive windshields, cured, and then fired in an oven to bum off the organic binder and fuse the ceramic into the glass windshield. ... 

Beyond the well known safety glass commonly used in automotive windshields, glass laminates are incorporated as windows into trains, airplanes, ships, and nearly every other mode of transportation. 

The experiments were conducted in cold rooms and in an icing wind tunnel in a temperature range of -dO C to -1°C and with wind velocity up to 100 m/s. The range of heating density, W, varied from 500 wW to 250 kW/m. In this paper we present results obtained on a prototype of an automotive windshield deicer. The deicer was made of 356 mm x 356 mm x 6mm soda-lime glass sheet coated with 0.3 pm layer of indium tin oxide (ITO), a common transparent conductor. The ITO layer had a sheet-resistance of 8 ohm and was scratch-protected with an approximately... 

Other applications of the technology under development are an automotive windshield deicer, non-slip shoes, a pulse brake for automotive tires, and a building-roof deicer.

Solbit is a neoprene, round ribbon which has an electric wire in the centre. It is non-tacky when delivered, but it must be stored at -4°C to prevent any vulcanisation. It is used for bonding and sealing of automotive windshields as shown in Fig. 98 when the electric wire is plugged under 24 V, this heats the rubber which becomes sticky after 30 s the windshield is pressed firmly against the ribbon, and it takes some 4 min to vulcanise the rubber. 

We found that the surface morphology of thin films derived from mixture of TEOS and MTES sols can be controlled by changing molecular weights of siloxane polymers in TEOS and MTES (Takahashi, 1997). We describe the method to produce low refractive index film and discuss the mechanism of formation of different surface morphologies. A new layer to reduce the reflection of the automotive windshield for drivers has been developed by sol-gel method. 

The largest single application for polyurethane adhesives is the structural bonding and sealing of automotive windshields. New formulations designed for the windshield-replacement market have demonstrated the development of rapid strength which facilitates rapid drive-away times in as short as 30 minutes after application...
