RUBEROID® SEBS
MODIFIED ASPHALT LITE
ASTM D-312, Type III
Description
GAFMC RUBEROID® Modified Asphalt Lite is an SEBS Modified
Asphalt that meets or exceeds all requirements of ASTM D312, Type III,
and several of the requirements of ASTM D6152. RUBEROID Modified Asphalt
Lite 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 Lite is manufactured using heat and
weather resistant SEBS polymer and formulated asphalts that provide greater
elongation, elasticity, low temperature flexibility, and toughness, when
compared to conventional oxidized roofing asphalt.
Advantages
RUBEROID Modified Asphalt Lite, 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 Lite 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 Asphalt Lite is compatible with Built-Up Roofing and mop applied
Modified Bitumen Systems.
Sizes
RUBEROID Modified Asphalt Lite is available in 60 lb., (27.2 kg) (approx.)
self release fiber kegs.
Application
RUBEROID Modified Asphalt Lite is designed to be used in accordance
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.

contact the GAFMC Technical Service
Hotline at 1-800-ROOF-411.
