ARCONATET" 1000 Propylene Carbonate

Cleaning/Flushing Agent

Methylene Chloride Replacement

ARCONATE Propylene Carbonate is an easily handled, high boiling, oxyrenated solvent exempt from Rule 66-type ordinances. I t has a low order of toxicity and broad solvent powers for organic and inorganic materials. I t may replace methylene chloride and other more toxic or more expensive solvents in many applications. ARCONATE PC may be blended with N-methyl Pyrrolidone, G-butyrolactone, ARCO-Solv@ propylene glycol ethers and acetates, or other materials to optimize solvency for a particular application.

ARCONATE PC has a l o w order o f toxicity based on oral and dermal acute toxicity testing. It is a moderate eye irritant and a slight skin irritant. Good hygienic and work practices should be followed when using ARCONATE PC including the use of skin and eye protection. Detailed information is contained in the Material Safety Data Sheet which is available upon request.

ARCONATE PC is not classified a hazardous waste under RCRA criteria. However, i t i s the responsibility of the user of products to determine i f a product, a t the time of disposal, meets RCRA criteria for hazardous waste. I t is our experience that many states also consider ARCONATE PC a non-hazardous waste. Disposal may be simplerlless expensive than for methylene chloride.

Incineration of organic materials in an appropriately designed and licensed incinerator is the preferred method of disposal. Regulations may differ from state to state. Your regional EPA office or your state environmental agency may be helpful in interpreting the law and identifying approved disposers and drum reconditioners. ARCO Chemical does not have analytical facilities to evaluate waste, nor can ARCO Chemical accept waste for treatment, storage, or disposal.

Additional handlingldisposal suggestions for ARCONATE PC spills and containers:

o Spills must be diked to prevent f l o w to public waters, and recovered by use o f absorbents or other means. The contaminated material should be placed in drums and either burned or landfilled, depending on its I iquid or solid state.

0 Empty ARCONATET"' PC containers should be hauled a w a y for sale o r clean-up by licensed waste disposal f i r m s accompanied by appropriate manifestos. I f they are to be cleaned and reused by t h e customer, the contaminated flush water may be consolidated and disposed of with other non-hazardous aqueous waste.

See ARCONATE Propylene Carbonate technical brochures a n d the MSDS for additional information. Contact your regional EPA office or your state invironnental agency for assistance in interpreting the law and identifying approved disposers.

ARCONATE Propylene Carbonate is an easily handlec. nian boiling, oxygenated solvent exempt from Rule 66. It pas a low order of toxicity and broad solvent powers for orcanic and inorganic materials. It is a cyclic ester and unaercoes most reactions typical for rhis class oi products For examole. ARCONATE PC reacts with amines to form carbamaies undergoes nyaroxy alkylation reactions (often succeesrnq where propylene oxide reaction is ditiicult), transesreri' lication and the formarion of polycarbonates Hydrolysis of

)RCONATE PC yields propylene glycol TYPICAL APPLICATIONS ARCONATE PC is compatible with isocyanates ana is use0 as a reactive diluent to reduce cost and to improve hanoling and processing properties in the following applications

9 Isocyanate t PMDI) Woodbinders/Adhesives 9 Urethane Foams 9 Urethane Coatings/Elastomers!Adhesives 9 Foundry Sand BindedResins

ARCONATE PC is compatible with most resin sysrems including phenol-formaldehyde, epoxy, polyester ana polyurethane. Depending on the system. ARCONATE PC may act as a solventldiiuent, accelerator reactive inter- mediate, compatibilizer, dispersing agent, wetting agent scavenger or some other function It may replace methylene chloride, dimethyl formamide and other more hazaroous or more expensive products in the above or other applications. eg., cleaning and flushing operations

ARCONATE PC has numerous applications in the texrile and synthetic fiber industries which utilize its outstanoing solvency and reactivity.

ARCONATE PC may be used for extraction of liquic petroleum fractions and to treat natural gas having hicn CO, levels. MOLECULAR STRUCTURE OF JRCONATE PC (DIOXOLANONE)

ARCONATE ?C is an excellent solventldiluent for isocyanates (MDI/PEVIDI\ anc may oe used to flush equipment or to clean drums m c m e r coniainers. However, two precautions are necessary: (1 1 spproved seals and gaskets must be used and (2) moisiure musr be k e ~ r from the system.

Buna N. Vilon ana Hypalon are softened by PC Telfon is the preferred gasket marerial. but EPR, neoprene, polyethylene, polyoropyrene. cork ana natural rubber are satisfactory.

If moisture IS present in a mixture of PC with 0-1 5% isocyanate. the miflure may gel or precipitate if allowed to stand for several hours. Atmospheric moisture is suff icient to promoie this conmion. This is a dilution phenomena since mixtures nigh in isocyanate content simply sklm-over. There IS no reaction Derween MDI and PC under normal conditions. so if moisture IS kept from the system a MDI/PC mixture is srable

SAFETY AND HEALTH

ARCONATE PC is pratically non-toxic based on oral and dermal acute toxicity testing. It is a moderare eye irritant and a sliaht skin irritant. Good hyoienic anc work practices should be followed wnen using ARCONATE PC including the use of skin and eye protection.

COSMFTIC APPLICATIONS/ TOXICOLOGY

PropAer5 Carbonate IS used as a polar additive for montmo::kme or ben?c;nlte clay gellants. These gellants are wide!:/ used as k s e s for an!tperspirants, lipsticks, skin cleansers. eye shadcvi. mascara. hair conditioners and other cosmetic oroducts.

Undiluied PC produced minimal to moderate ocular irrita- tion and sliaht erythema in rabbits. The dermal LDso in rabbits oi the undiluted ingredient was greater-than 20 ml/Kg. Undilulea PC was nontoxic by inhalation to dogs and guinea pigs in a 21 -day study. PC was negative for mutagenicity in the Ames Assay, and negative for genotoxicity in the Rai Hepatocyte Primary CultureIDNA Repair Test. In Clinical studies unciluted PC caused moderate skin irrita- iion. whereas 5 and 1 0 % PC in aqueous solution produced no skin irritation or sensitization.
