BERMOCOLL® products are based on cellulose, a natural polymer derived from wood or plant fibers and we offer the following main cellulose ether types, Ethyl Hydroxyethyl Cellulose (EHEC) and Methyl Ethyl; Hydroxyethel Cellulose (MEHEC). BERMOCOLL®cellulose ethers are unique in the industry and have been developed to impart a range of properties in drymix mortars. Depending on the end-user requirements, BERMOCOLL® products provide: increased water retention, improved consistency to make thin layer products workable, controlled rheology to provide sag resistance, reduced segregation of different formulation ingredients, improved adhesion on porous substrates, optimized air pore stability for improved workability and improved adhesion to polystyrene boards.
