Isothane EMA Mechanism

ISO THANE EMA elastomeric membrane is a liquid applied coating based on urethane perpolymers which cure by reaction with atmospheric moisture to give a continuous film which is elastic. It contains leafing aluminium which gives execellent U.V. resistance.

ISOTHANE EMA is a very high solids coating designed to give a high build film. It can be brush or spray applied (with airless spray equipment) but it has a higher viscosity than a conventional paint and should not be diluted.

ISOTHANE EMA curves to a permanently flexible seamless membrane which, by virtue of its chemical reactivity in the wet state has good adhesion to a wide ranges of substrates (given proper preparation) such as roofing asphalt, slates, tiles, asbestos, concrete, brick, wood, glass and metals. Unlike more traditional bitumen based product ISOTHANE EMA does not readily embrittle with age, exposure to ultra violet radiation or weathering and hence it does not crack or craze.

Since it is elastomeric ISOTHANE EMA is not adversely affected by extremes of temperature, consequently it does not crack at low temperatures or suffer thermal flow at elevated temperatures.

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

APPLICATION
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 sprayed polyurethane (p.u) foam insulation. However, it is essential that substrate and structures are properly prepared, and stable.
