Low modulus construction PU Sealant is single part polyurethane based, high/middle modulus sealant, which cures on exposure to atmospheric moisture to form elastomeric mastic, has excellent adhesion on all cement based materials, brick ceramics, polyurethane, epoxy, most polyesters, most metals and most timbers.
Where to use
Construction PU Sealant is suitable for bonding or sealing joints between most construction materials, where a high bond strength is required. Trafficable floor joints
Assembly of metal framed buildings
Cover plates and covings
Bolted lap joints
Prisons, gaols, grand stands
Modest hardness after curing, flexible, durable and easily applied
No sagging, no pollution and corrosion to base material and environment
One component, moisture curable, excellent thiotropy, convenient for applying
Excellent sealing performance, extrudability, excellent water and aging resistance
Ensure surfaces are dry and free from oil, grease and dust.
Carefully pierce seal at end of metal tube with reverse end of cap, Attach nozzle to tube and cut to desired opening.
Apply bead along length of joist, stud or batten, on broad flat surfaces apply beads every 40cm.
Bring surfaces together as soon as possible(within the first 10mins)
Fix with sufficient nails, screws or clamping to hold load and achieve contact over the total bond area.
After use, remove nozzle and replace cap.
Allow adhesive to set(min.24 hours) before removing any temporary fastenersor clamping. Use with mechanical fasteners in high stress applications.
Strong adhesive property to most material, after applying, it can bond the parts very strong, it is non-corrosion, and long life.
