Chem-Set MS-35: One-Part, High-Performance Hybrid Sealant and Adhesive
Chem-Set MS-35 is a one-component, high-modulus, mildew-resistant, multipurpose silyl-terminated polyether (hybrid) elastomeric sealant and adhesive. When fully cured, this unique VOC compliant formula offers UV stability and firm bonding to a wide variety of substrates, including PVC, concrete, glass, aluminum, painted surfaces, wood, plywood, marble, metal, and more. We often refer to the MS-35 as “silicone on steroids”.
Here’s what makes MS-35 the ideal choice for your sealing and bonding needs:
- Combines the best qualities of urethane and silicone sealants: MS-35 offers the high strength and durability of polyurethane with the elasticity and weather resistance of silicone.
- High early green strength/same day painting: MS-35 cures quickly, allowing you to paint the sealed surface on the same day, saving you time and labor.
- Bonds to most substrates without priming: MS-35 adheres to a wide range of substrates without the need for primers, simplifying your application process.
- Wide range of applications: MS-35 is suitable for various applications, including panel mounting, sealing precast concrete, industrial gaskets, transportation seals, marine cabins, appliance trim & parts, interiors/exteriors, above-grade applications, sealing openings & exterior surfaces, HVAC/R, plumbing, roofing, kitchens & baths, countertops, and sanitary seals.
- Easy to use: MS-35 is a one-part sealant, eliminating the need for mixing and reducing the risk of application errors.
- Durable and long-lasting: MS-35 is 100% solids, contains no solvents or isocyanates, and offers excellent resistance to UV degradation, weathering, and water washout, ensuring a long-lasting and reliable seal.
- Low odor and eco-friendly: MS-35 is VOC compliant and low in odor, making it a safe and environmentally friendly choice for indoor and outdoor applications.
In addition to the features mentioned above, MS-35 also offers the following benefits:
- Vibration damping
- Improved aesthetics
- Low dirt pick-up
- Speed and ease of application
- Paintable with most consumer and industrial latex paints
- Can be applied in damp and wet environments
By combining the strengths of polyurethane and silicone sealants, MS-35 offers a versatile and high-performing solution for a wide range of sealing and bonding applications.
