Description
Chem-set™ MS-35 White is a one-component, high early green strength, high performance, non-sag, multi-purpose elastomeric, silyl-terminated polyether adhesive and sealant. The MS-35 is a great alternative to 100% RTV Silicones (like RTV4500) in that the MS-35 combines the sealing capabilities of a silicone but also provides the strength of a construction adhesive.
Features & Benefits:
- Combines best qualities of urethane and silicone sealants
- High early green strength/same day painting
- Bonds to most substrates without priming
- Wide range of applications
- Ready to use, reduces labor costs
- Easier to match part contours
- Vibration damping
- Improved aesthetics
- Low dirt pick-up
- Speed and ease of application
- Save application steps
- Ideal for vehicular, signage and any application where a standard silicone is not normally strong enough
