EMA Elastomeric

Overview

Our EMA elastomeric membrane product is a solar reflective, liquid applied coating based on urethane prepolymers.

Manufactured to cure by reaction with atmospheric moisture to give a continuous film which is rubbery and elastic. It contains leafing aluminium which gives excellent U.V. resistance. EMA is a very high solid coating designed to give a high-build film. It is applied by brush but it has a higher viscosity than a conventional paint and should not be diluted.

EMA cures to a permanently flexible seamless membrane that, by virtue of its chemical reactivity in the wet state, has good adhesion to a wide range of substrates. Unlike more traditional bitumen based products, EMA does not readily embrittle with age, exposure to ultra violet radiation or weathering, and hence it does not crack or craze. It is not adversely affected by extremes of temperature consequently it does not crack at low temperatures or suffer thermal flow at elevated temperatures.

EMA can be applied by brush, squeggee or roller without the need to mix, stir or heat before application.

EMA is also available as a spray grade which is applied using airless spray equipment.

Isothane elastomeric membranes are designed to bond to many types of substrate particularly those commonly used as roofing, such as felt, asphalt, slate, tiles, asbestos, concrete, brick, wood, glass and metals. They can also be applied to spray polyurethane (pu) foam insulation. However, it is essential that the substrate and structures are properly prepared, and stable.
