Advantage EP-980

Advantage EP-980 is an emulsion polymer isocyanate system (EPI) developed specifically to meet AC05 and ASTM D 7446 for use in the manufacture of Structural Insulated Panels (SIPs) comprised of OSB or mineral board with EPS core. It should be used with conventional cold press equipment. Advantage EP-980 emulsion is mixed with Hardener 200, a polymeric isocyanate, at 100 parts emulsion to 15 parts Hardener 200. This adhesive has no-added formaldehyde and offers a long working time, as well as exceptional heat, water and solvent resistance, making it ideal for demanding applications. Advantage EP-980 is also characterized by good spreader stability and low foam production when compared with traditional EPI adhesives.

    listing ESR-3845

 
 

POT LIFE

The pot life of these systems is in excess of one hour at 77 degrees Fahrenheit (25 degrees Celsius), but will vary depending on temperature. However the viscosity of the mix will increase as it ages, and foam will be generated.



MIXING INSTRUCTIONS

Advantage EP-980 resin is mixed with Hardener 200 at a ratio of 100 parts resin to 15 parts Hardener by weight or 6.45 parts resin to one part Hardener by volume. Avoid mixing for long periods of time or with excessive agitation as pot life is affected by mixing time and speed. Product can be easily mixed by hand. Substrates glued with older material will have less water resistance, a characteristic common to most EPI adhesives. Therefore, it is recommended that fresh adhesive be mixed only when it is to be immediately used. EPI adhesives also generate foam during the reaction process; so it is best to have the material continually moving.

APPLICATION GUIDELINES

Spread rate: EPI adhesives have superior gap filling properties due to their higher percent solids content. Spread rates of 270 - 370 g/m² are recommended for larger area applications requiring longer working times, such as SIP manufacture, but optimal spread rates should be verified by plant trials. Generally, 200 g/m² of glue line is adequate for millwork applications. Roller spreaders are commonly used in gluing applications. In general, verify that adequate coverage exists by evaluating squeeze-out along the glue lines of pressed panels.

Clamping pressure: Pressure is dependent upon the materials being glued. Direct contact of the gluing surfaces must be made to obtain maximum strength. Typical pressures used during SIP manufacture are
5 - 7 psi. See EPS manufacturers for specific information regarding acceptable pressures used with EPS cores.

Press/clamp time: It is recommended that optimum press times be determined in actual plant conditions, recognizing that seasonal changes may lead to variable requirements. Press times generally vary from 30–60 minutes, under ideal conditions at factory temperatures of 68 degrees Fahrenheit/20 degrees Celsius. Longer press times may be required for colder factory temperatures. A Franklin representative can set up a trial to evaluate the appropriate minimum press time required for a specific manufacture facility.

     At 70°F and 50% relative humidity, based on spread rate of 270 – 370 g/m2:
     Open Assembly Time – 3 minutes per panel for best results
     Closed Assembly Time – 30 minutes per load for best results 

Working pauses: The spreader should be kept running during pauses in production for lunch breaks, etc. to help extend the working life of the adhesive.

Clean-up: The foaming and cross-linking characteristics of EPI may cause blockages in the wastewater plumbing. Furthermore, there may be disposal concerns with the mixed product. It is recommended that the excess glue from the spreader and mixing containers be poured into a container and disposed of properly. Avoid sealing the container for at least 24 hours to permit EPI components to finish reacting. Glue pans and rollers may then be washed in warm water.
 

HANDLING AND STORAGE

Shelf life: Best if used within nine months of date of manufacture. Extended shelf life testing is underway. Product is freeze-thaw stable. If it becomes frozen, allow to warm to ambient temperature and thoroughly mix until a homogenous, smooth mixture is obtained.

Storage of Hardener: Hardener 200 is very susceptible to moisture. We recommend that it be kept in a sealed container. A desiccant or nitrogen blanket is recommended.

Safety and disposal: Hardener 200 is a polymeric isocyanate. Use of gloves and other protective equipment is recommended. Consult MSDS before use for additional information.
