AT 4430 - ALPHATEK ROOF COATING
AT 4430 - AlphaTek Roofing Coating is a single-component, water-based, fire-rated siloxane-acrylic engineered elastomeric coating. AT 4430 provides excellent insulation protection and is a very effective weather barrier for many types of insulation and roofing materials. It provides excellent UV protection. It exhibits superior adhesion to many substrates and has a high hide capability to create an aesthetically pleasing appearance. The coating is designed to dry faster than most acrylic coatings. Unlike most cool roofing solutions, AT 4430 combines reflective AND thermal insulation properties. AT 4430 therefore provides highly efficient insulation performance over multiple years thereby reducing maintenance and total lifecycle costs while delivering maximum ROI in energy savings.
