CADMIUM

Leading h e a i and light stabilizer for clear or opaque stock, an organic liquid complex containing no disadvan­tageous soapy component. Unequalled for stabilizing against effects of sunlight or outdoor aging.

lÀRIUMrC^JWIUM

Leading combination of coprecipitated laurates for out­standing performance, where lubricating advantages are required- Genera l ly 3 0 % more effective than common barium-cadmium laurates.

Stabil izing Systems developed for H a r s h a w Customers, for special processing and finished product properties, m a y contain one of the fol lowing fourteen stabil izers.

Z I N C 9 - V - l : Organic liquid complex containing no disadvanrcgeous soapy component used in selected formulations.

C A D I U M 2 - V - 7 : For modified solutions and organosols. C A D I U M 2 2 8 - V - 1 : For rigids, clear to translucent. C A D I U M 2 4 - V - l : Organic liquid complex for highest attainable clarity, used prin­

cipally with dispersion resins. C A D I U M 2 - V - 8 : Selected laurate, used principally with low fusing resins. Β Α - C D 1 2 - V - 5 : Coprecipitated laurate. O R G A N I C 7 - V - l : Epoxy assistant, modification o f 7 - V - 2 . O R G A N I C 7 - V - 4 : Expoxy assistant, for rigids. B A R I U M 1-V-3: Dispersible stéarate, to contribute lubricity with barium effects. B A R I U M 1-V-6: For asbestos filled tile. B A R I U M l - V - 7 : Liquid, for modified plastisols a n d organosols. C A L C I U M 5 - V - l : Dispersible stéarate, to contribute lubricity with calcium effects. C A L C I U M 5 - V - 2 : Low melting stéarate, to reduce internal friction effects. C A - Z N 5 9 - V - 4 : Non toxic metai content.

Best effects are attained for particular requirements by combining 2-V-4 or 128-V-5 i n a stabil izing system w i th one or more o f the f o l l o w i n g three stabil izers.

BARIUM l - V - 4

Compatible barium compound, minimum effect on viscosity. Permits processing at higher temperatures.

ORGANIC 7 - V - 2

Epoxy assistant, highly effective HC!-scrubbing agent, undiluted. Will extend stability for longer processing periods.

ORGANIC 8-V-1

Chelating agent, more than two times as effective as common organic phosphites. Inactivates harmful by-products to boost stability. Contributes to top clarity.

CADMIUM 2 8 - V - 2

For rîgîds, opaque to translucent. Stabilizes unplasticized resin efficiently and economi­cally, with minimum effect on physical prop­erties of product.
