Adhesives Inventory July 2010

ADHESIVES INVENTORY July 2010

Alaska State Museum

Ellen Carrlee, Conservator

 

PURPOSE OF THE INVENTORY:

1. I like to scan the list before selecting an adhesive for treatment to make sure I am considering all my alternatives.

2. Keeping obsolete adhesives helps me think about what may have been used on an artifacts in our collection, as well as monitor its aging under natural conditions on the lab shelf.  If something looks like hell in the bottle, I have to wonder how it is faring on the artifact.

3. The inventory lets me know at a glance if I have a certain adhesive so I do not re-order something we already have and waste money.

 

WATER-BASED ADHESIVES:

Acrylic Medium Gloss Daniel Smith 8 oz plastic jar

Acrysol WS-24 1 gallon plastic jug, nearly full still liquid but quite old from Rohm and Haas in Philadelphia.

Methylcellulose One Quart plastic jar, powder, 1980’s or earlier

white powder that is used as a synthetic substitute for natural gums. It forms a highly viscous colloidal solution in cold water that reversibly gels when heated. Methyl cellulose dries to a clear film with very little shrinkage. It has been used as a substitute for gelatin and glue in sizing paper and has been used as an adhesive in textile and paper conservation (Kuhn 1986). Methyl cellulose has also been used as a poulticing material to pick up stains; as a poultice the addition of fumed silica minimizes depth penetration while the addition of glycerin adds flexibility. Methyl cellulose is sometimes found as a binder in pastels and watercolor paints. In industry, methyl cellulose is used as a lubricant, suspension aid and emulsifier. It is used in foods, leather tanning and cosmetics. Aging studies indicate that methyl cellulose (MC) polymers have very good stability with negligible discoloration or weight loss (Feller and Wilt 1990).

PVA Polyvinyl acetate emulsion in large ½ gallon plastic jar from Light Impressions  and two smaller applicator bottles.  April 1999.

one of the most widely used water-dispersed resins. Polyvinyl acetate water-based emulsions have been used as latex house paints, artists’ media (since 1938), and common household white glues. Setting is accomplished by the removal of water due to evaporation or absorption into a substrate. PVAC resins produce clear, hard films that have good weather resistance and withstand water, grease, oil, and petroleum fuels. Additional properties are high initial tack, almost invisible bond line, softening at 30-45C, good biodegradation resistance, poor resistance to creep under load, and low cost. Polyvinyl acetate resins and copolymers are also used as hot-melt adhesives, sealants, fabric finishing, plastic wood, and inks  pH is acidic

prepared by kneading equal portions of each stick together until mixed. Milliput® shapes readily; surface drying can be minimized with a few drops of water. Before it hardens, acetone can be used for smoothing. The putty sets in 1 hour and hardens in 2-3 hours. Once hard, Milliput® can be sanded, drilled, cut, or filed. It adheres to wood, metal, plastic, glass, and porcelain. Milliput® is available in pure white, yellow-green, gray, and terracotta colors and may be tinted during mixing or painted after drying.

When hardened, Milliput is resistant to water as well as most solvents and chemicals
