PRODUCT DESCRIPTION
Introducing the HM-SS5549 Silicone Weather-Resistant Adhesive for construction, a marvel from Nanjing Howell New Material Technology Co., Ltd. This innovative adhesive is a one-component, neutral curing, low modulus, and highly elastic silicone rubber that offers unparalleled performance. Enjoy superior elasticity and exceptional displacement deformation abilities, along with excellent adhesion to a variety of powder-coated metals. Its thixotropic nature prevents sagging, making it ideal for non-structural bonding, and ensuring outstanding weather resistance and waterproof sealing for diverse curtain wall designs. With a wide range of climate adaptability, it delivers reliable adhesion and compatibility to most substrates without the need for a primer. Once cured, it stands resilient against aging, UV radiation, and extreme temperatures from -50°C to 150°C. Boasting low modulus performance, it effortlessly accommodates expansion and displacement of interfaces up to ±25%, making it a versatile solution for bonding and sealing.
FEATURES
1. Superior anti-aging properties
2. Robust resistance to ultraviolet radiation
3. Withstands extreme temperature fluctuations from -50°C to 150°C
4. Low modulus performance for flexible applications
APPLICATION
1. Ideal for glass curtain wall applications, aluminum-plastic panel curtain wall installations, and door/window sealing and caulking.
2. Perfect for non-structural adhesive assembly of various curtain walls.
3. Versatile for sealing and caulking between metal and aluminum alloy doors, windows, and walls.
