Key Product Points:

• Fire resistant up to 4 hours in both horizontal and vertical joints
• Can be used in joints up to 60mm wide
• Non-slump, easy to apply and tool off
• No priming required for most substrates
• Contributes to Green Building
• Highly flexible and waterproof

Key Installation Points:

• For good adhesion the surfaces of the building elements shall be free of any dust or grease and may need to be primed. On good, clean virgin concrete & masonry, no priming required, though refer to substrate compatibility requirements
• Ensure that the aperture and services in question are tested with Pyrolastic Silicone and the site conditions are within the application specification. An annular space needs to be present around the service to apply sufficient installation depth
• Consider the movement of the joint to be sealed. This should include thermal, wind pressures, settlement and differential movement of components
• Consider the characteristics of the substrates as they affect the choice of sealant i.e. how the surface finish may be affected by sealant compounds and the possibility of discolouration due to oil migration or staining
• Consider the location and environment of the joint to be sealed. Exposure to temperature extremes, ultraviolet light, radiation, chemical attack, standing water and vibration
• Consider the characteristics of all available sealants for performance capabilities, hardness after weathering, movement capabilities, in both extension and compression, adhesion properties and chemical resistance
• Adequate space and accessibility should be provided for applying and tooling the sealant. Mineral wool (80kg/m³) or PE backing rod where required can be used as backing materials, though the Pyrolastic Silicone should be installed correctly to achieve the performance needed
