What is silyl terminated polymer?
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.
Is polymer sealant the same as silicone?
In addition to this, silicone is an inorganic compound not as strong or durable as polymer based products. These, in contrast offer long lasting protection. Polymer has a much greater cohesion strength. Tests show that it can remain flexible up to 350% at the break point, compared to about 280% with silicone.
What are polymer sealants?
The Polymer A paint sealant is a fully synthetic product that is comprised of polymers that chemically bond onto the paint surface. When they ‘flash’ it provides a stronger layer of protection than car wax and will last longer than car wax.
What is hybrid polymer sealant?
What is a hybrid sealant? Unlike common silicone sealants, hybrid options typically use polymer technology to blend silicone and polyurethane. The result is a powerful sealant, available in a range of colours including black, white and crystal clear, that can also operate as a hybrid polymer grab adhesive.
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.
Is polymer and polyurethane the same?
Polyurethanes—and a handful of coloured silicones—contain isocyanate as a curing agent. Polymer-based sealants and adhesives do not. Polymer-based silicones, sealants and adhesives are also solvent-free, making the use of them onsite far better for the environment, especially where rain encourages run off.
Is polymer and polyurethane the same thing?
Polyurethane is a polymer. A polymer consists of repeating units that are chemically linked in a particular pattern. Some of the repeating units are urethane groups. The term polyurethane simply means that it contains multiple urethane groups.
What are hybrid sealants?
Hodgson Hybrids are the next generation of adhesive sealants. They combine the flexibility and elasticity of a sealant with the strength of an adhesive. The result is a durable, multi-use product for all sealing, bonding and filling needs.
How do you remove hybrid polymer adhesive?
Step 1: Cut the cured sealant down to a thin layer of 1mm or less in thickness. Step 2: Use a scarification technique, such as with an electric sander, to remove the remaining sealant. Step 3: Clean the residue with a citrus-based cleaner.
What is silyl protection?
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.
