Polymer Roofing Asphalt

Crafco manufactures and distributes a variety of polymer modified asphalt Roofing and Specialty materials used in the manufacture of Shingles, Built-up Roofing membranes, Waterproofing and Water Storage systems. Polymer modified asphalt technology offers improved performance characteristics to these Roofing and Specialty materials. The ability to extend and improve the asphalt’s base performance specifications by greater flexibility at cold temperatures, accommodates greater thermal movement, improved thermal cycling and impact resistance.

Rubberized Waterproofing Membrane

Crafco Rubberized Waterproofing Membrane is a hot-applied asphalt based composition that is specifically formulated as a fluid membrane that when applied forms a continuously adhered waterproofing system. The membrane material is simply melted in an appropriate indirectly heated melter, poured or pumped onto the prepared surface, and then leveled to a thickness of at least 1/8-inch to form a seamless waterproofing membrane. Crafco Rubberized Waterproofing Membrane is used to waterproof various types of Portland cement concrete surfaces including recasts and poured in place roofs, bridge decks, tunnels and parking structures. The unique properties of this membrane permit its use in re-roofing operations over a variety of substrates including gypsum and wood surfaces.
Since Crafco Rubberized Waterproofing Membrane is designed as a low temperature (-15° F) flexible, crack bridging elastomeric waterproofing material, applications are typically protected from traffic loading, abrasion, puncturing, and UV radiation by an appropriate surface covering. Crafco Rubberized Waterproofing Membrane meets all requirements of Canadian General Standards Board specification 37-GP-50M, "Standard for: Asphalt, Rubberized, Hot Applied for Roofing and Waterproofing.

Shingle Tab Adhesive

Crafco Shingle Tab Sealant is a specially formulated and manufactured asphalt composition that is used as a sealant for shingle tabs and is applied during the shingle manufacturing process. The sealant provides improved performance characteristics compared to typical oxidized asphalt sealant materials. Improvements include increased tackiness, which results in enhanced low temperature shingle sealing, improved low temperature flexibility, and improved toughness and fracture and squish resistance.

Polymer Roofing Asphalt

Crafco Polymer Roofing Asphalts are modified asphalt materials that are used in roofing construction as elastomeric interply adhesive, flood coat waterproofing membrane. The formulation and manufacturing process yields a material with greatly improved elongation, elasticity, low temperature flexibility, and toughness when compared to conventional oxidized roofing asphalts. Crafco Polymer Roofing Asphalt is manufactured using heat and weathering resistant SEBS polymer systems and specially formulated asphalt. Crafco Polymer Roofing Asphalt can be heated using conventional heated roofing kettle and applied using standard handling and mopping techniques.
Use of Crafco Polymer Roofing Asphalt in combination with appropriate polyester of fiberglass felt base, ply, or cap sheets produces roofing systems which have superior fatigue cracking resistance, tensile strength, low temperature flexibility and puncture resistance as compared to conventional built up roofing systems. A variety of product specifications are available to accommodate roof slope/pitch and climatic temperature regions.

Laminating Adhesives

Crafco Laminating Adhesive is a hot-applied polymer modified asphalt composition which is suitable for a variety of laminating and adhesive applications in the construction industry. Such uses include packaging adhesives and roofing shingle laminating. Crafco Laminating Adhesive offers significant improvements including increased aggressiveness enhanced low temperature shingle sealing and improved low temperature flexibly.
