What is Expandable Polyurethane Foam Sealant ? Expandable Polyurethane Foam Sealant  is dispensed as a frothy liquid which expands and moisture-cures into a solid foam insulation and sealant. One-component foam is used to fill and seal small cracks and voids such as around door and window frames, sill plates, electrical devices where air leakage and energy loss can occur. Formulations are available for general use and specific applications such as sealing windows and doors, fire blocking, and construction adhesive. How to use PU foam Sealant Adopter / Straw Type PU foam Spray can Clean the application area with water spray Moisten the area with Water spray .PU foam adheres to almost all surfaces that are strong, clean and free of dust and grease. Only silicon, oils, greases, polyethylene,Teflon or similar surfaces are not suitable for PU foam. Surafce must be dampened enough to ensure that the PU foam finds adequate moisture for its hardening process. Otherwise, it could imp

Construction SEALANTS – Terminology, purpose, typical applications, Typical Sealed Building Products and Materials    What’s the difference between a caulk and a sealant? A caulk is any low or intermediate performance compound. Typically being lower quality and having limited service lives. For example: Acrylic Latex, Butyl, Butyl Rubber, Co-polymers, putty etc. Life cycle: usually 3 – 5 years. A sealant typically refers to a high performance compound having more expensive ingredients, little shrinkage, excellent weathering and UV resistance and providing long service life cycles from 10 – 20 years. Construction Sealants – Terminology ASTM C 920   is t he standard specification for elastomeric joint sealants. It is made up of several ASTM test methods including: – Movement capability (ASTM C 719) – Sealant hardness (ASTM C 661) – Tack free time (ASTM C 679) – Adhesion in Peel   (ASTM C 794) Sealant Hardness – ASTM C 661 Is a measure of a sealants ability t
