Specific Properties and Uses:
Ultraviolet Absorber Benzophenone-12 is a kind of excellent and highly effective aging-resisting auxiliary. It can absorb ultraviolet light in 240-340nm. It is light -colored, non-poisonous, highly-compatible and easily-processible. It can provide the most effective protection for polymers and be very helpful to reduce coloration while working yellowing and loss of the physical performance. It can be widely used for PE,PVC,PP,PS,PC,organic glass,polypropylene fibre and vinyl acetate and so on. In addition,it can provide very good light-stabilizing effect for dry novolaks and alkyd varnishes, polyamino esters, acrylic acids, epoxides,other air dry products, paints for automobile, powder dopes and rudder products,etc.
