What is a silyl terminated polymer?
Silane modified polymer (SMP), also known as silyl terminated polymer or silyl modified polymer, consists of a polymer backbone which is terminated by silane groups. The former are often preferred as sealants as they are more elastic and slightly less resistant than SPUR polymers.
What are STPE?
STPE technology is a hybrid product of silicone and polyurethane technologies. By combining these chemistries, it brings together the most desirable features of each and creates a durable, high quality product. Other common names for this chemistry include MS Polymer, SPUR, Polyether, STP and SMP.
What is SMP sealant?
Description: Mastersil SMP 25 is an elastomeric, one-component, thixotropic paste based on silane-modified polymer (SMP) technology with excellent UV…
What is polymer MS?
MS Polymer Adhesive & Sealant is a highly elastic, high strength sealant and adhesive. Modified silicone polymers (MS Polymers) offer the best all round sealant and adhesive on the market, it excels where elastic construction joints are required. It is odourless, neutral and free of isocyanates.
What is the purpose of silyl ether?
Silyl ethers are usually used as protecting groups for alcohols in organic synthesis. Since R1R2R3 can be combinations of differing groups which can be varied in order to provide a number of silyl ethers, this group of chemical compounds provides a wide spectrum of selectivity for protecting group chemistry.
What is polysulfide sealant?
Polysulfide sealants are designed for joints that need to withstand prolonged immersion in liquids. Typical applications include swimming pools, fountains, cooling towers, fuel and chemical storage tanks, wastewater treatment and petrochemical plants.
What is a polyether sealant?
Description: Clear is a high quality moisture curing elastomeric sealant formulated with polyether technology for use in virtually any high visibility sealing application.
What is SMP technology?
SMP Technology began in 1992 as a specialized designer and manufacturer of LAN interconnect products. Today, SMP has evolved into a diversified organization that serves a broad base of customers in the computer, industrial, instrumentation and telecommunications markets.
What is silane based adhesive?
What is Silane Technology? Silanes are considered the “glue within the glue” as well as “adhesion promoters.” It creates a mechanical bond with wood and penetrates into the cell structure of wood. A mechanical bond is when molecules interlock but do not change the chemical make-up of those molecules.
Is polymer better than silicone?
They are both used for sealing and bonding applications, across many industries. The benefits to using MS polymer adhesives, are that they are stronger and have a higher green strength than silicone adhesives, as well as a faster cure. However, silicones are easy to work with, and will bond to almost anything.
What is polymer sealer?
ALEXSEAL® Premium Polymer Sealer is a non-abrasive synthetic sealer designed for cleaning and protecting surfaces painted with polyurethane. It is formulated with UV absorbers that will help protect the paint from exposure to the sun and improve the coatings’ life expectancy.
How do I get rid of TES protecting group?
Various tert-butyldimethylsilyl ethers are easily removed in excellent yields by treatment with a catalytic amount of N-iodosuccinimide in methanol. This method allows a selective deprotection of TBDMS ethers of alcohols in the presence of TBDMS ethers of phenols.
