RUBEROID® SEBS
MODIFIED ASPHALT
ASTM D-312, Type III or IV
Description
GAFMC RUBEROID® Modified Asphalt
is an SEBS Modified Asphalt that meets or exceeds requirements of ASTM
D312, Type III or Type IV, and several of the requirements of ASTM D6152.
Modified Asphalt is used in the roofing industry as an elastomeric adhesive
and waterproofing agent when mopping in - insulation, base sheets, interply
sheets, cap sheets, and gravel. RUBEROID Modified Asphalt is manufactured
using heat and weather resistant SEBS polymer and formulated asphalts that
provide greater elongation, elasticity, low temperature flexibility, and
toughness, as compared to conventional oxidized roofing asphalt.
Advantages
RUBEROID Modified Asphalt, when used with fiberglass or polyester sheets,
produces a roofing system that greatly improves elongation, fatigue cracking
resistance, tensile strength, low temperature flexibility, and puncture
resistance, when compared to conventional Built-Up Roofing Systems using
oxidized asphalt. RUBEROID Modified Asphalt can be heated using a conventional
roofing pump kettle and applied using standard handling and mopping techniques.
For
complete loading, handling and mopping instructions, contact the GAFMC
Technical Service Hotline at 1-800-ROOF-411.
Uses
RUBEROID Modified Asphalt is compatible with Built-Up Roofing and mop
applied Modified Bitumen Systems.
Sizes
RUBEROID Modified Asphalt is available in 60 lb. (27.7 kg) (approx.)
self release fiber kegs.
Application
RUBEROID Modified Asphalt is designed to be used with GAFMC's GAFGLAS®
products and systems as well as GAFMC’s RUBEROID mop applied Modified Bitumen
roofing materials.

WARNINGS
CAUTION: COMBUSTIBLE.
The container for GAFMC Roofing Asphalt is NOT intended for unprotected
long-term storage. To assure asphalt usability and optimum storage duration,
take the following precautions:
- Protect containers from adverse weather conditions and prolonged exposure to sunlight.
- Closed storage areas must have sufficient ventilation to avoid heat build-up
- Store upright as asphalt will flow from tipped containers, the hotter the weather the quicker the flow
- Store out of water. Do not stack cartons.
For information,
contact the GAFMC Technical Service
Hotline at 1-800-ROOF-411.
