Single Component MS Polymers
MS Polymers are flexible adhesives that cure with moisture. They are ideal for applications that require a high degree of resilience and excellent environmental resistance.
The high green strength (strength of the uncured adhesive) along with relatively quick skin over time (the time required for the surface to be dry to the touch) allow full curing to continue unattended. The full cure is dependent on relative humidity, temperature and depth of cure needed. Cure time for many moisture cure adhesives is best stated in depth of cure over time. For example, products may cure 4mm deep in 24 hours. The maximum depth before the moisture is blocked from curing the MS Polymer further is 10-15mm.
Two Main Types of MS Polymer Applications
Bonding MS Polymer Applications: Require the flexible adhesive to be spread or squeezed into a thin bead or film include bonding trailer truck panels or office furniture panels. The desired properties include very low adhesive shrinkage so that there is no “read through” or visible deformity of the materials being bonded.
Potting MS Polymer Applications: Range from outdoor potting and sealing of construction materials to small delicate electronic materials. The low shrink, flexible adhesive does not damage delicate components.
Two Component Modified Epoxies
Permabond Modified Epoxies have similar properties to MS Polymers but are two component systems. These materials are still very flexible adhesives but they cure to a slightly harder material, with higher shear strength, and develop strength more rapidly than MS Polymers. Two component Modified Epoxies will cure within 72 hours regardless of the depth of cure area.
Permabond modified epoxies are conveniently packed in dual cartridges and easily dispensed through a static mix nozzle which eliminates manual weighing/measuring and mixing.
