Hilastic 88 is particularly recommended for sealing lap joints in Zincalume, Colorbond, Marviplate, and other Bluescope decorative sheet metals. Hilastic 88 is also suitable for use in window manufacture. Technical Support Parchem offers a comprehensive range of high performance, high quality construction products. Parchem offers a technical support package to specifiers and contractors as well as on-site technical advice from staff experienced in the construction industry. Properties Data quoted are typical for these products, but do not constitute a specification. Form: Non-slump, thixotropic paste Colours: Translucent, White, Grey, December 2009 Page 1 Black, other colours to batch order Physical or chemical change: Chemical cure, moisture activated Application temperature: Minimum 5°C Service temperature: Minus 50°C - 150°C Tooling time: Up to 10 minutes Movement ± 25% (total 50%) accommodation factor Chemical resistance to occasional spillage: Resistant to dilute acids and alkalis. Not resistant to organic solvents Application Instructions Joint preparation All joint surfaces must be clean, dry and free from any rust, oil, dirt or loose material. Metal and glass surfaces should be cleaned with Solvent 10. Note: Priming is normally not required when lap jointing Zincalume, Colorbond and similar finishes, provided the surface is absolutely clean and free from any trace of surface contamination. For advice on other applications, or where Hilastic 88 is to be used with other substrates, contact your local Parchem office. Application Fit the cartridge of Hilastic 88 into a normal cartridge gun, and gun firmly onto one surface. On metal surfaces immediately combine the assembly to ‘sandwich’ the sealant and mechanically fasten the components using screws, rivets, etc. Clean up Where it is desirable to remove excess visible sealant, wipe using Solvent 10. Any sealant allowed to cure becomes very difficult to remove. Design Criteria Hilastic 88 is primarily designed for use in mechanically fastened lap joints in sheet metal applications. For sealing applications where significant movement is likely, consideration should be given to one of the other Parchem elastomeric sealants. Contact your local Parchem sales office for further advice. December 2009
