Application Suggestions Use directly without dilution. Agitate well before using. Do not add additives such

as defoamers. Keep container tightly capped during storage. Avoid returning used

adhesive to container. Select screen mesh based on required adhesive coating

thickness and printing precision. Stainless steel, polyester and nylon wire in the

range of #70 to #150 can be used for screen mesh materials. Water resistant

materials such as acrylics or diazos should be used for mesh masking materials.

Storage and Shelf Life Store in original container. Temperature not to exceed 105°F (40°C). Keep from

freezing.

Shelf life is 12 months from date of shipment when stored in original container and

temperature is kept between 40-95°F (5-35°C).

Some liquid separation from the adhesive during storage is normal. This liquid

should be remixed into the adhesive by low-shear, mechanical agitation. Mixing by

hand is adequate for small volumes of adhesive.
