	ACIDUMA Aciduma is a two part pack silicate type cement which resists all acids, hot and cold, with the exception of hydrofluoric. It also withstands temperatures up to 1400C. Whereas Aciduma cement can only be used as a jointing material the Aciduma patch and concrete can be used as monolithic materials i.e. as an alternative to bricks and tiles. ACIDUMA CEMENT This cement has excellent adhesion characteristics and high tensile joint strength. ACIDUMA CONCRETE Aciduma Concrete is a graded aggregate/cement mix which is ideal for laying floor areas which are subject to acid attack but where toughness and resistance to heavy trafficing are not a major factor. ACIDUMA PATCH Aciduma Patch can be rendered over a vertical surface but it is important to obtain a good key to existing brickwork by raking out joints, roughening as much as possible and for large areas using some measure of support such as anchors or meshing.
	APPLICATIONS Bedding and jointing of vitrified bricks and tiles in floors, benches, pipes and channels, acid plants, tanks, vats, towers, and retorts, chimney linings, bonded brickwork, in acid laden soil. It should not be used in any application where there is prolonged exposure to alkalis.
	ALCUMA CEMENT Alcuma Cement is a combination of polyester resins with inert fillers supplied as a two part pack. It sets very hard and permanently withstands the action of acids, alkalis and most solvents. The cement has exceptional adhesive properties not only to bricks, tiles and earthenware but to metal and similar dense surfaces.
	APPLICATIONS Alcuma is used for bedding, jointing and pointing vitrtfied tiles and bricks in construction and maintenance of chemically resistant floors, benches, tanks, channels etc. It can also be used for jointing and sealing pipes that carry acids and alkalis. Alcuma permanently resists all mineral and organic acids, all alkalis both in solution and in solid form, all salts in the dry and liquid state, acidic, alkaline and neutral mineral, animal and vegetable oils, fats and greases and most solvents. It should not be used where temperatures exceed 127C nor continuously operate above 104C. It is not advised for use under intensely oxidising conditions or in constant contact with fuming nitric acid, petroleum ect. When Alcuma is used for pointing only it is essential that bricks or tiles be impervious.
