DESCRIPTION

Bond It MEGA FOAM is a one ­component polyurethane assembly foam, and is based on a moisture curing polyurethane prepolymer. It is a fast setting, multi­purpose PU foam which bonds, fills, seals and insulates most construction materials

• ­Multi­directional valve
• 360° application
• Can be used either as a gun grade version (EasyGun ­ Pat. EE05028, EP2004520, US2009174183) or as an aerosol version. ­
• Higher yield
• ­More foam per can with less waste ­
• Longer life compared to a standard can
• ­Specially Coated Valve ­- problem free and will not corrode

USES

The fresh foam adheres to all common building materials except from surfaces such as polyethylene, silicone, oil and grease and similar substrates. 

• Window and door setting (where a clean and controlled backfill is required),
• Entrance door linings
• Any kind of small breakthroughs in walls and other cavities
• Pipe and cable entries.

SUBSTRATE PREPARATION

• Surfaces to be bonded must be firm, clean, dry and free from dust, grease or contaminants that may hinder adhesion. They must be moistened well with water. (It is advisable to apply a primer well penetrating into the ground if necessary.) All construction components must be properly prepared prior to foam application. It is advisable to have Foam Cleaner at hand. The ideal working temperature for both the can and environment is +20°C. Chilled cans must be carefully warmed in luke­warm water before usage. However, the can must not be heated above +50°C, as there is a risk of bursting. Cans which are too hot, for example after having been left in a vehicle during summer, must be cooled in water. The can should be shaken occasionally during this process to obtain the required temperature faster. Prior to work, and before the adaptor or gun is attached, the can must be shaken thoroughly for at least 30 seconds to mix the contents. Then the adaptor is attached firmly to the valve. Care must be taken not to overtighten the adaptor and not to activate the valve during this process.

APPLICATION INFORMATION

• The instructions for the can must strictly be observed. The fresh foam will expand by 1½ to 2 times. Therefore care must be taken not to overfill joints. Fresh foam spills must be removed immediately within the tack­free time with Foam Cleaner. Cured foam must be removed mechanically. Please Note: Moisture is needed for an even and rapid curing of the foam. Inadequate moistening or overfilling of joints and cavities may lead to an unwanted post­expansion of the foam. Foam extrusion can be controlled accurately by varying the pressure on the adaptor or gun trigger. For foam extrusion the valve is best pointed down, but it will work through 360° . The valve lever is to be activated carefully. Once a can has been started, it should be used within four weeks.
