Culminal GAP (green aware performance) 0540 is a modified methylhydroxyethylcellullose for ecological friendly formulations in cementitious tile adhesives (CTA) when moving from CEM I to less CO2 emitting composite cement binder systems. With this move, there are a number of key performance parameters in today's ecological formulations which are difficult to meet, which are addressed with Culminal GP 0540, such as low impact on cement hydration, faster strength development, high final tensile strength, excellent workability, excellent sag resistance, improved setting at low temperatures and more.
