Children as well as adults seem to enjoy the family convertible. M&T is making that enjoyment last longer by supplying vinyl manufac­turers with stabilizers which help keep the vinyl rear window clear . . . and safe.

It's clear today. Will it crack tomorrow? Art and Science: Chemists have been working for over twenty years to perfect vinyl stabilization systems. But, there is still some doubt about the mechanism by which heat, light, and weather attack various vinyl materials.

However, we have learned a great deal about which chemicals will pre-

Sometimes we forget. Sometimes we just don't bother to put the hose away. Unless it's made of stabilized vinyl it soon cracks from exposure to heat, light and weather.

vent degradation; for example, many organotin compounds, barium-cad­miums, and zinc.

M&T now supplies a complete line of stabilizers which can be used alone or sometimes in combinations to give exactly the kind of stabiliza­tion required for a particular product or end use.

Thermolite® 31 is a good example. It gives such outstanding perform­ance in clear and pigmented formu­lations that it is the most widely used organotin for stabilizing rigid vinyls. Also, being the most powerful stabil­

izer know, it is used here and abroad as a standard for testing other sta­bilizers.

Some Thermolite stabilizers are best for clarity, others for eliminat­ing plate-out problems, some offer excellent high temperature stability, others are designed for non-toxic applications.

To find out which is right for your product or end use all you need do is call your local M&T representative.

Stabilize food and other products: While most of the publicity has gone to organotin chemicals as stabilizers for PVC, we shouldn't forget that hundreds of patents have been issued that deal with all kinds of tin chemicals as stabilizers for foods, fuels, lubricants, paints, rubber, soaps, and many other materials.

Take food for example. There's a patent (U.S. 2,785,076) which covers the use of stannous chloride or stan­nous sulfate to stabilize frozen pine­apple against the development of off-flavors.

T h e r e ' s ano the r p a t e n t (U.S. 2,914,213) covering the use of these same tin salts to prevent attack and corrosion of metal containers which carry carbonated beverages and cer­tain fruit juices.

Pineapple seems a long way from vinyl plastics. Yet tin chemicals can be used both to protect and stabilize vinyl and preserve the odor and taste of pineapple.

patents pertaining to stabilization additives which deal with the use of tin chemicals... chemicals from the simplest salts of tin to some of the most complex organotin com­pounds which can be synthesized.

Handy reference on stabilizers: As the nation's leading manufacturer of tin chemicals we do our best to keep abreast of all that is going on in this field. Because so many of our cus­tomers find it useful we have pub­lished a bibliography of patents and pertinent literature on the "Uses of Tin Chemicals as Stabilizers."
