Trial Number 4

Trial Purpose:

Evaluating cleaners for removal of 590 adhesive.

Date Run:


Experiment Procedure:

Five cleaners were selected based on the previous trials. A sixth cleaner was also evaluated based on client request (590 Stripper). Luminox was used diluted to 30% with DI water in a 250 ml beaker. The 590 Stripper was made up according to client specifications, 5 oz into 1000 ml beaker. The remaining four cleaners were used at full strength. DS 108 was heated to 100 F and the other five were heated to 140 F on a hot plate. Eighteen preweighed ceramic coupons were coated with the Crystalbond 590 by heating the adhesive with a heat gun. After cooling to room temperature, "dirty" weights were measured. Three coupons were cleaned in each solution for 60 minutes. Observations were made after 10, 40 and 60 minutes.

Trial Results:

Two products, Buckeye Shopmaster and Ecolink Safe Strip, removed nearly all of the Crystalbond 590. Two other
products, Dynamold DS 108 and Aremco 590 S Stripper removed over 80% of the contaminant. See Table 1 below
for the efficiencies for each cleaner.
