Butyl 310 is an elastomeric coating providing excellent UV protection and superb resistance to moisture penetration. Once cured, this sprayed applied polymer provides a durable, seamless, flexible waterproof membrane that resists cracking and will allow for the normal expansion and contraction. Butyl 310 is also a vapor retardant coating, making it ideal for use over spray polyurethane foam in cold storage or freezer applications.

  • Reflects 80-90% of heat caused harmful UV rays
  • Excellent reflectivity
  • Superior elongation and tensile strength
  • Highly resistant to dirt collection
  • Reduces daily expansion and contraction (thermal cycling) of roofing substrate

Butyl 310 is recommended as a protective vapor barrier coating to most surfaces as well as roof applications, including a variety of situations such as polyurethane foam, seams, fasteners, gutters, vent pipe flashings, air conditioning units and expansion joints. Ideal for metal buildings that may contain visible rust.
