Elastomeric Acrylic Waterproofing
DIATHON 4500 is a 45% solids, 100% acrylic elastomeric coating. Superior weatherability, ultraviolet resistance, fire retardance, adhesion and ease of application make DIATHON 4500 an excellent coating for the protection of polyurethane foam on roofs and tanks.
DIATHON 4500 was especially developed to provide protection for sprayed-in-place polyurethane foam roof and tank systems. The thixotropic consistency of DIATHON 4500 gives it excellent vertical hold, allowing uniform build on the highs and lows of the polyurethane foam texture without pinholing or sagging. DIATHON 4500 is also an ideal choice for recoating existing polyurethane foam/coating roofs and tanks. It has the ability to "wet" into the surface and achieve excellent adhesion to aged acrylic or urethane coatings. |
