China Fire And High Temperature Technology Annual Meeting WACKER introduced a new fire protection coating substing

China Coatings Online News Information: Wacker Chemical presented an innovative emulsion that can be used as a base for water-based expansion-resistant fire protection coatings at the annual conference on fire prevention and high temperature resistance technology in Qingdao. This fire-resistant coating can "wrap" the steel beams of the building and create a heat barrier for a certain period of time in the event of a fire, prolonging the stabilization time of the building's load-bearing structure. As a substrate, the new VINNAPAS®Wei-Neshe®EZ3066 emulsion not only foam forming and stability is excellent, the adhesion and strength of the product has also been improved, so that the protective layer firmly adhered to the substrate.
steel structures, which are widely used in public and commercial buildings, must be fire-resistant in order to gain valuable evacuation time in the event of an emergency fire. Inflated fire-resistant coatings "wrap" building steel beams so that the building's load-bearing structure does not bend or melt quickly in the event of a fire. The coating usually only needs 1 to 4 mm thickness, in the heat can expand to the original thickness of 10 to 100 times, so the foam layer thermal conductivity is very low, can delay the heating rate within the coating, so that the steel beam in a certain period of time from the fire high temperature, extend the stability of the structure time.the
VINNAPAS®Weiser®EZ3066 emulsion is a new substrate developed by WACKER for expansion-type fire-resistant coatings, which is based on ethylene acetate-ethylene co-polypropulation emulsion, has excellent foam forming and expansion properties, as well as long-lasting foam stability, while improving the adhesion and strength of the expansion coating, so that the protective layer firmly adheres to the substrate, and forms a thermal barrier for a certain period of time. If the substrate is not added, the foam layer becomes too brittle to adhere well to the steel substrate and cannot meet the requirements for flame retardant coatings. VINNAPAS®Weeney®EZ3066 has demonstrated excellent performance in fire testing: the expanded coating thickness is more than 50 times the original thickness, fully up to the F90 fire rating, in a specific formulation can reach F120. (F90: Fire resistance limit 90 minutes; F120: fire resistance limit 120 minutes.)
In addition, this low odor water-based substation does not contain any additives such as organic solvents or plasticizers, and does not use alkylol polyoxyethylene ether (APEO) materials in the production process, suitable for the preparation of a new generation of environmentally friendly and healthy water-based coatings.
