ReacTITE 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. ReacTITE 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. ReacTITE EP-980 is also characterized by good spreader stability and low foam production when compared with traditional EPI adhesives.
• Emulsion polymer isocyanate system (EPI) developed specifically to meet AC05 and ASTM D 7446 for use in the manufacture of Structural Insulated Panels (SIPs) • Meets requirements of Norma Ch2148 and approved for residential use in Chile • Low foaming EPI adhesive with good spreader stability and long assembly time • Recommended for applications requiring water, heat and solvent resistance • Excellent for cold pressing • Low film formation temperature, which allows it to be used at a wide range of plant temperatures • Meets the definition of NAF for CARB and TSCA Title VI • Tested according to reference method EN 16516 and meets German formaldehyde emission requirements for wood-based materials
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.
ReacTITE 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.
Bonding Strength (ASTM D 7446 screening)
Shelf life: Best if used within nine months of date of manufacture. 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 nitrile gloves and local exhaust ventilation are required. Consult SDS before use for additional information.
