摘要:
The present invention provides radiation-curable compositions and products coated therewith, such as coated optical fibers. The present compositions have a low amount of, or are even absent of, reactive diluents while still exhibiting a sufficiently low viscosity to be useful in a wide variety of coating applications, such as in processes for coating optical fibers.
摘要:
A novel method for producing thick composite parts based upon photopolymerizable compositions is disclosed. The constituents of the photopolymerizable mixture comprise a monomer or monomers capable of polymerizing by free radical or cationic mechanisms, and a photoinitiator system which possesses an absorbance characteristic which is effectively reduced, or self-eliminating, upon initiation of the polymerization reaction. Parts having thicknesses up to 2 cm and thicker for varying end use applications are made by photopolymerizing such compositions. In addition, using such compositions composite parts can be made using a reinforcement material such as a glass fiber mat present in an amount by weight of from about 5 to about 70%.
摘要:
A thermoformable decorative automotive laminate includes a flexible free film comprising a transparent UV light-stabilized cellulosic outer film, an optional primer, ink layers, and an opaque layer. The cellulosic outer film may include cellulose acetate butyrate and/or cellulose acetate propionate. The cellulosic film may he laminated to a polymeric sheet or film and thermo-formed to a three dimensional shape while maintaining a high gloss and DOI along with durability properties suitable for interior or exterior automotive use.
