Description:
Synthetic resin polymer emulsions are fine suspensions in water, based on one or more of the following principal monomers: acrylic esters, acrylonitrile, fumaric and maleic diesters, met acrylic esters, ethylene, styrene, vinyl acetate and higher vinyl esters, vinyl chloride and vinylidene chloride, Plasticizers, e.g. dibutyl phthalate, may also be present.
The Technical data sheet for each individual polymer product specifies the type of monomers used and plasticizers if present

Hazards and Precautions :
Emulsions have low fire and toxicity hazards; they do not present any undue hazard when handled with care and as long as good standards of industrial and personal hygiene are practiced.
Emulsions contain traces of residual monomers usually discernible by their characteristic odors; other materials that may be present in small amounts include ammonia, formaldehyde, micro biocides and trace impurities derived from the monomers. Most emulsions contain surfactants or colloids, necessary for the dispersion of the monomers during manufacture, for the subsequent stability of the product, or to raise viscosity and impart special flow characteristics; apart from polyvinyl alcohol, other colloids used are the cellulose ethers, starch ethers, dextrin and natural gums.
At the end of each polymerization process our emulsions are post treated where necessary to reduce residual monomer to a very low level, so as to render them non hazardous under normal working conditions.
The polymerization reaction is initiated with compounds such as peroxides and persulphates, and may be controlled or stopped with a variety of chemicals. All these additives and their breakdown products constitute only a very small proportion of the final product, and have little if any effect on the low hazard entailed in using emulsions

Fire and Explosion :
Since emulsions are water based, flammability is not a hazard; the small amounts of volatile organic substances present have never been known to cause a fire or explosion.
|
| |
Health Hazards :
The toxic hazard is low, in keeping with small amounts of volatile compounds in emulsions. Adequate ventilation should be provided where large amounts are processed, especially in a confined space, Spray from emulsions must not be inhaled, and respirators or masks should be provided if extraction equipment is inadequate. Discharges from all ventilation and exhaust systems should be carried well clear of the workplace and of any neighboring houses or other buildings. Although there is no fire hazard, smoking should be prohibited.
|
| |
Ingestion :
Emulsions must not be swallowed, although they are not poisons in the accepted sense; small quantities are unlikely to cause more than temporary discomfort. The preparation and consumption of food and drink in the work place must nonetheless be prohibited.
