Subject: Elvace


From: Walter Henry <whenry>

Bobbie was kind enough to send the product data sheets and MSDS for
Elvace 40-705, which I've attempted to transcribe.  Please obtain an
MSDS from the supplier and read it for further information on
health/safety matters.  Because of the difficulty of reading MSDS's
properly I don't think it appropriate to post the raw text.

    As I stated you can purchase Elvace(r) 40705-00 directly from
    Reichold, even in 5 gallon quantities.  For quantities less than 55
    gallons, the price is $2.705 per wet pound.  You will need to pay
    for shipping.  5 gallon quantities ship via UPS.  This product is
    manufactured in Morris, IL.  However, we store this product in our
    Cheswold, DE facility and would be shipping your product from the
    Delaware location.

    (formerly Elvace Vinyl Acetate-Ethylene Copolymer 1875)
    Vinyl Acetate-Ethylene Copolymer

    A vinyl acetate-ethylene copolymer emulsion

    Designed as a base for general purpose adhesives

    Tough permanently flexible polymer film
    Excellent viscosity build with plasticizer addition
    Superior adhesion to packaging film and foil
    Poor borax tolerance
    Excellent resistance to plasticizer migration
    Short bond development times
    Greater resistance to hydrolysis when compared to a polyvinyl
        acetate homopolymer.
