Seamseal BR

Solvent release rubber bedding sealant, which forms a tight elastic seal. Very good adhesion to a number of building materials.

APPLICATIONS

Suitable for bedding aluminium window frames into timber subframes; sealing seams in joints and ductwork; roofing and cladding sealing where a thin joint is required e.g. flashings; sealing profiled foams filler and general bedding and joint sealing in automotive, leisure and boat building.

• Good performance in low movement joints
• Excellent weather sealing properties
• Capable of accommodating some movement
• Adheres well to a wide variety of surfaces
• Good resistance to mould
• Good resistance to dilute acids and alkalis
• Remains pliable once cured

PROPERTIES

Application temperature range: +5°C to +30°C rate of cure will depend on ambient temperature and relative humidity.
Priming: Primers are not normally required for good adhesion to most non-porous surfaces.
Shelf life: 12 months in unopened packaging when stored in cool, dry conditions.
Skinning time: An initial skin will form after approximately 4 hours.
Working time: Tooling can be carried out with a wet spatula within 10 minutes of application.
INSTRUCTIONS

Joint design: Please consult the Technical Information Sheet entitled ‘Joint design for cartridge based products’ prior to application.

Surface preparation: All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed
Cut the top of the screw thread off the cartridge and screw on the nozzle. Cut nozzle to correct diameter for joint size. Apply using a skeleton or powered gun into the joint ensuring good contact with surfaces.

Tooling: Tool immediately with a spatula wetted with white spirit within 10 minutes of application.
