DESCRIPTION
RB-MA 20 is hot pouring system sealant based on polymer modified bitumen with excellent adhesion to different materials such as concrete, metal, wood and any other masonry materials. It has high resistance to deterioration due to weathering, ultra-violet light, hot climate and hydrocarbons derivatives such as fuel, grease, oil and gases.
Joint size:
RB-MA 20 joint size ranging from 10-50mm wide and width: depth ratio should be 1:1.5 for expansion joint and 1:2.5 for construction joint.
As a durable flexible sealant in the following extension and implementation seams: concrete roads, parking spaces and highways, streets, ceilings, balconies, parking lots, water supply channels, wastewater treatment plants. Applicable to horizontal and sloping surfaces.

As RB-MA 20 is hot pouring sealant, it requires special indirect heating vessel, the temperature should be controlled perfectly (at 170±5 0C) by means of a thermostatic switch, otherwise there is a risk of overheating which may cause curing of the RB-MA 20 prior to pouring.
In melting process, before product boiling point, reduce heating to prevent the product from burning.
Surface preparation:
Surfaces must be free from any dirt, dust and loosely materials, any oil and grease must be removed. Surfaces must be dry.
