Laseal/Kastar MS Polymer is widely recognized as a premium base resin for producing moisture curable sealants, adhesives, and coatings. The polymer consists of a polyether backbone and silaned terminal functionality.
A complete toolbox of MS Polymer is available, differentiated by the backbone structure, functionality, and viscosity range. Although the primary use has historically been as construction sealants, the range and blending capability of these resins allow the formulator to design products for a broad variety of other markets.
MS Polymers are considered to be “hybrid” molecules because they provide the best properties of polyurethane and silicone while limiting their individual inherent weaknesses. For example, MS-based sealants combine the strength of polyurethanes with the weathering resistance of silicones. In addition to their unique performance and application properties, these polymers have achieved widespread acceptance due to their solvent-free and isocyanate-free nature.
Here, we will review the formulation versatility of MS Polymers™ that allows the customization of viscosity and early strength development for various applications. Also, learn how simple formulation and blending can provide sealants and adhesives that are matched to exact performance and application properties. In this way, MS Polymer can extend their value propositions to applications not previously recognized.
