Styrene Butadiene Styrene (SBS) polymers have been used successfully for many years to modify asphalt for use in roofing and waterproofing. SBS polymers have the unique ability to form a network within the asphalt which modifies its behavior. The asphalt becomes elastomeric, or rubber-like, with the ability to stretch and recover in response to building movement and rapid changes in temperature. #637 Elastomeric Aluminum Roof Coating combines the advantages of modified asphalt with the reflective, UV blocking abilities of leafing aluminum pigments.
Aluminum pigmented coatings can substantially reduce interior building temperature and prolong roof service life. Polymer modified asphalts also provide much greater resistance to moisture and will perform better than standard Aluminum Roof Coatings in areas of ponding water. #637 may be used on asphalt, metal and modified bitumen roofs.
This product provides an ideal surfacing for SBS modified bitumen as the coating will form a cohesive molecular bond with the polymer modifiers in the roof membrane. When applied to metal roofs, #637 remains flexible and will accommodate building movement in lighter gauge metal better than traditional fibered aluminum coatings.
Lucas #637 Elastomeric Aluminum Roof Coating is formulated from specially refined asphalt, SBS polymers, aromatic and aliphatic solvents and 3 lbs. per gallon of ASTM D 962 leafing aluminum paste. Formulated to spread easily and evenly by brush, roller or spray.
