Review of Evonik's architectural coating defoamer performance with support of the COATINO® Defect Detection tool.

This webinar was organised by UL prospector in November 2021 and discusses the typical defects found in architectural coatings and offers product recommendations to solve these issues. 

This course provides some insights on the Evonik's defoamer portfolio for Architectural coatings and help formulators to identify the optimum solution for their system.

Quiz on Defoamers

Wall paints are a very important application within Architectural Coatings - and renewing them is quite laborious. Optimizing the resistance to damage and wear leads to more economical and sustainable paint formulations, as it makes renovation of e.g. façades with the costly installation of scaffolding redundant. One particular headache for freshly painted façades can be the formation of so called snail trails causing an uneven appearance when there is high humidity or rain. New specialty fillers help to prevent these problems and allow to formulate very long-lasting beautiful films when formulated e.g. with optimized hydrophobing agents. For interior coatings, innovative fillers also play a major role for optimization of mechanical resistance e.g., burnish phenomena - in addition, the use of suitable surface-active agents facilitates the optimization of scuff and chemical resistance. Studies of film formation help to understand and optimize both interior and exterior formulations.

This course introduces the new TEGO® Dispers 711W, 712W, 715W and 717W and TEGO® Foamex 2 and 9, a new product portfolio designed to meet the cost-performance requirements of  decorative paints.
