EPS® 2252

Polymer for Low Surface Energy Roof Coatings

EPS® 2252 improves coating performance for basecoats and primers applied to roofing substrates.

EPS® 2252

is a high solids acrylic emulsion designed to adhere to low energy substrates commonly used in roofing. Basecoats and primers based on EPS® 2252 offer outstanding adhesion to new thermoplastic olefin (TPO) and ethylene propylene diene monomer (EPDM) rubber. EPS® 2252 provides the capability to formulate coatings at <50g/L VOC.

Applications

  • Primers

  • Basecoats

Benefits

  • Excellent adhesion to TPO, EPDM, metal, asphalt, and other common roofing substrates.
  • <50 g/L VOC capable
  • Can be used in both primer and basecoat formulations
  • Formulated without APEOs

Formulating Guidelines

  • Pigments: Careful selection of pigments is critical to many end-use properties, such as adhesion and water uptake. For optimal adhesion and water uptake performance, it is recommended that small particle size extenders be used, such as calcium carbonate. The PVC has also been shown to impact the adhesion to low energy substrates; highly filled systems may negatively impact adhesion and should be evaluated.

 

  • Dispersants & Surfactants: The use of and level of dispersants, surfactants and wetting aids may impact the adhesion performance properties of the roof coating. A ladder study is recommended to determine the optimum level.
