The difference between silicone and polyurethane sealants is in their chemical composition: silicone is inorganic while polyurethane is organic and less chemically resistant. Silicone is essential to seal around bathtubs, showers, lavatories, etc. The flexible nature of elastomeric polyurethane sealant means that the materials that make up the sealed joint can move, expand, and contract, without rupturing the seal. Privacy Policy - They may be prone to damage by strong acids and certain solvents, however. They bond particularly well to porous substrates like concrete and masonry. An existing low-slope built up roof in climate zone 2A as acrylic, butyl, polyurethane can be of. ; roof coatings such as silicones may withstand very high bond strength are Often 45 mils ; HypalonR and PVC a flexible shield against the passage fire and smoke, adhesion flexibility. An example of data being processed may be a unique identifier stored in a cookie. Either silicone or polyurethane sealants can do the job. While the initial application process takes about the same amount of time for each material, the frequency in which you will have to repair and replace the polyurethane sealant can be much higher.
