LABORATORY DATA
|'VA adhesive formulations using different plasticizers were made up and evaluated in our laboratories. ta*.c formulation consisted of 11 parts of plasticizer in 100 parts of polyvinyl acetate emulsion. Data tabu* U'rd Mow will allow the adhesive formulator to choose the most suitable plasticizer for the adhesive proper ty k*'ired.

TOWXXrCiTXr4ND SAFE HANDLING INFORMATION
* TKe iieutr orat toxidly tofdrocior 1242 shows it to have an LD*0 to rats of 4.15 ml./kilogram. Presumably the other two ^f^prponrpwjnds are in the same toxicity range. Repeated or prolonged skin contact with these compounds is tff-be avoided- Inasmuch as their processing in this use does not require the use of elevated temperatures; there shauld.be no hazard from vapor exposure.
