Urethane Brush-Grade 522

Urethane Brush-Grade 522 is a high solids, single component, moisture cure polyurethane elastomeric coating formulated to a thick consistency in order to bridge gaps for water-proofing situations on commercial flat roof surfaces.

Advantages
  • Superior Protection – forms a durable, weather resistant “rubber-like” seal
  • Superior adhesion
  • Superior elongation and tensile strength
Basic Uses

Urethane Brush-Grade 522 was developed from the Aromatic Urethane 520 as a mastic to create a waterproofing system with the Urethane 520 and other AWS coatings. With excellent adhesion, it can be used for protection of conventional surfaces such as, but not limited to, EPDM single-ply membranes, concrete, masonry, metal, and polyurethane foam.

Butyl Brush-Grade 320

Butyl Brush-Grade 320 is a single component, brush-able grade seam sealer specially formulated to provide a waterproof, weather-resistant membrane with excellent permeability and ultra-violet protection. It also offers excellent elongation and tensile strength to resist lateral movement and allow for expansion and contraction of the substrate. 

Advantages
  • Superior Protection – forms a durable, weather resistant “rubber-like” seal
  • Ideal for sealing holes, cracks, and joints
  • Highly flexible
  • Superior elongation and tensile strength
Basic Uses

Butyl Brush-Grade 320 is recommended as a protective vapor barrier seam sealer for a variety of situations, including all types of seams, fasteners, gaps between metal panels, gutters, vent pipe flashings, air conditioning units and expansion joints. Ideal for metal roof applications with visible rust and all types of flat roofing substrates.
