Mixing for Use

Adcote 502S should be mechanically agitated in the drum prior to catalyzing or diluting. Combine 100 parts of Adcote 502S with 6.5 parts Coreactant F or 5.2 parts Coreactant 9L10 just prior to use. Dilute as desired with the urethane gra de solvents and mix thoroughly.

High molecular weight polyesters that are used in solution adhesives like Adcote 502S have a tendency to form a reversible structure in solution with time. This structuring is accelerated when the adhesive is exposed to te mperature below 50o F. The structuring is reversible if heat and shear is applied to the adhesive. We recommend placing the container of adhesive inn in a steam cabinet, allowing venting of the container and heating to 110~ 120 o F. After the adhesive reache s the proper temperature, mix the adhesive in the container 1~3 hours under moderate shear. Use of a disperser or “Cowles” type blade will

shorten the time needed.

Caution must be taken because of the flammability of the solvent used in the adhesive. Plea se review

MSDS for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a homogeneous mix. Before using the adhesive, check to make sure that all resin has returned to a true

solu tion and no gels remain.

Adhesive Application

Adcote 502S can be applied by gravure, smooth roll or reverse roll techniques. The adhesive is generally applied to the less porous, more stable substrate.

Adhesive Weight

Approximately 3.2~6.4 grams of dr y adhesive per square meter will generally provide excellent results in laminations of light gauge substrates. Higher adhesive weights may be required in laminations of heavy gauge substrates and/or where high degrees of thermal or chemical resistance are required.

Drying

Use sufficient temperature and air velocity to assure comp l ete solvent removal. Oven temperatures in the range of 200~250oF are generally suitable.

Laminating Combining

Laminate to the second substrate using heated pressure nip roller s at a temperature high enough to assure complete wetting of the secondary substrate. A minimum temperature of 170oF is recommended, however, temperatures approaching 350oF may be required to obtain optimum adhesive performance in laminations of heavy gaug e substrates or where adhesion is of prime importance.

Bond immediately off the laminator is fair. Maximum thermal and chemical properties will develop within 7~14 days. For high performance applications, post

- curing at elevated temperature of 120~150oF i s
recommended.Adcote 502S August 2009 Page 3 of 6

Alcohols and similar materials containing active hydrogen can react with Adcote 502S adhesive system causing inadequate cure.

Adcote 502S can react or interact with other components of laminations. Retained solvents, slip additives, anitblock agents, and contaminated solvents are some of the components that may cause property changes of the film and/or adhesive.

Safety, Handling and Storage

 Store in cool, dry, well ventilating area.

 Follow good manufacturing and handling practices.

 Wash thoroughly after handling. Wash contaminated goggles, face shield, and gloves. Professionally launder contaminated clothing before re

- use.

 ATTENTION! Container can be hazardous when empty. Follow label warnings even after container is empty. Do not r euse empty container without professional cleaning.

 Refer to Material Safety Data Sheet for more information.
