Silane terminated polymers, sometimes referred to as silane modified polymers (SMPs), are often used to create flexible bonds and seams in a variety of industries. These elastic materials offer permanent, high-strengths bonds that are compatible with a variety of substrates and typically provide good environmental resistance.
Silyl terminated polymers/silane terminated polymers are crucial in construction and manufacturing. They serve as adhesives, sealants, coatings, and more, providing strong bonding, waterproofing, and weatherproofing properties. These polymers enhance structural integrity and longevity in buildings, vehicles, and other engineered products.
Enhance your industrial applications with OSi Silicone's Silyl-Terminated Polymers (STPs) and Silane-Terminated Polymers, designed for high performance in moisture cure sealants, adhesives, and coatings. These advanced polymers offer a unique balance of durability, reactivity, and storage stability, making them an ideal choice for a variety of industrial and construction solutions.
Silyl-Terminated Polyether
OSi Silicone's silyl-terminated polyether (STPE) is a high-modulus polymer that provides higher strength, broad adhesion profiles, and wide formulating latitude. These properties are derived from the polyether polymer backbone coupled with methyldimethoxysilane functional groups. STPE-based formulations result in products with higher hardness, faster tack-free times, and long shelf stability. These characteristics make STPE an excellent choice for producing high-performance sealants and adhesives that can withstand demanding industrial environments while offering ease of application and reliable performance.
Silane-Terminated Polymers
Silyl terminated polymers provide environmental resistance, superior adhesion properties, and fast cures, combining many of the benefits of polyurethane and silicone sealants into one material. They are generally flexible, durable, tear resistant, and hold up well in low-temperature environments. OSi Holding Limited supplies silyl terminated polymers in a variety of colors.
Silane-terminated polymers from OSi Silicone serve as the main binder in sealants and adhesives, boasting a comprehensive technology platform. These polymers provide excellent primer-less adhesion to various substrates, permanent elasticity, high durability, and easy smoothening, making them a game-changer in construction applications. Additionally, they exhibit broad compatibility with various raw materials, allowing both physical and chemical processing to manage moisture effectively. Environmentally, these polymers are free from isocyanates, solvents, and other harmful substances, promoting safer use and compliance with high environmental standards due to their low VOC content.
Silyl Terminated Polymer / Silane Terminated Polymer Application：
In construction, sealants made with OSi STP or STPE polymers offer higher strength and better adhesion compared to silicone sealants, along with superior shelf life and weather resistance over PU sealants. For industrial applications, these polymers ensure bubble-free, non-yellowing, and eco-friendly sealants and adhesives, combining the best attributes of silicone and PU sealants. They are also ideal for waterproofing solutions, offering excellent water resistance, eco-friendliness, and durability.
So upgrade your products with OSi Silicone's advanced polymers, ensuring superior performance, environmental safety, and versatility in various applications. Choose OSi Silicone for cutting-edge solutions that meet the highest industry standards.
Advantages of Silyl Terminated Polymer / Silane Terminated Polymer:
● Elastic bonds and seams: SMP adhesive and sealant systems remain flexible also after complete cure. The elasticity of the seams and bonds is not affected even by harsh environments.
● Easy to modify: silane modified polymer adhesives and sealants can have different polymer backbones which partially define their set of properties. However, the properties can also be modified with help of additives and so-called boosters.
● Minimum surface preparation: in most cases through cleaning and degreasing of the surface is sufficient. Usually, these systems do not require a primer, thus the process is sped up. Note that some silyl modified sealant systems do not cure in the presence of polyols: therefore, the cleaning substance should not contain these.
● Silicone and isocyanate free: most silane modified polymer solutions are environmentally friendly as they do not contain silicone or isocyanates. Some products may emit methanol during the hardening process, but also ethanol emitting, safer systems exist.
● Good adhesion to most materials: silyl modified polymer adhesive and sealant products adhere to most substrates such as concrete, plastic and metal allowing for a wider variety of possible applications.
