REVACRYL AE 4522 is a specially modified, aqueous dispersion of a styrene-acrylic ester copolymer intended to achieve good wet adhesion. The dispersion contains an anionic emulsifier system and is free from film forming aids, solvents and plasticizers.

Technical Informations

Application Advice/Typical Applications

REVACRYL AE 4522 is preserved against bacterial and fungal attack. In the manufacture of finished products, the material has to be retreated, as usual, with suitable biocides to give enhanced preservation.

Above the minimum film forming temperature, REVACRYL AE 4522 forms a clear, tack-free, and water-resistant film characterized by good light, ageing and alkali resistance. Due to a special modification the dispersion forms a true chemical bond, notably to mineral substrates, resulting in very good adhesion, especially wet adhesion. Important applications are cement-free, ready-for-use dispersion adhesives for tiles which, according to DIN 18156, achieve tensile adhesive strength values of > 0.5 N/mm² after 21 d storage under water. REVACRYL AE 4522 has good compatibility with conventional pigments and fillers and has a high filler loading capacity. When lamellar fillers, e. g. kaolin, mica or talcum are used, the compatibility and storage stability may become limited. Combinations of quartz powder and carbonate fillers have proved effective in water resistant tile adhesives. It has to be ascertained that end products have good storage stability. For this purpose it the optimum quantities of wetting and dispersing agents have to be determined and used. Combinations of polyphosphates and dispersing agents such as NUOSPERSE® FX 504, Pigment Dispersant A or DISPEX® N 40 have proved effective. For adjustment of end product viscosity and rheology addition of cellulose ethers, copolymers containing acid groups (ROHAGIT® SD 15), polyurethane thickening agents (BORCHIGEL® DP 40, RHEOLATE® FX 1010), COLLACRAL® VL and inorganic thickening agents (BENTONE® EW) is recommended. For lowering the minimum film forming temperature the addition of such products as diverse DOWANOL® grades, DAPRO® FX 511, LUSOLVAN® FBH or TEXANOL® is recommended. Aromatics- containing white spirits and butyl glycol are suitable, but greater quantities have to be added because they are less effective. Suitable defoaming agents are, inter alia, DAPRO® GBR, AGITAN® 218/281, BYK®-034, DEHYDRAN® G.

Shipping and Storage

This product is supplied in road tankers or in non-returnable plastic drums secured by a lid with clamping ring or in non-returnable palletized bulk containers (net volume 1.000 lt). The product must be protected from frost and exposure to direct sunlight. Storage temperatures between +5 °C and +30 °C are recommended. The product contains in-can preservation to protect it against microbiological attack during transportation. For protection against microbiological contamination during storage stringent plant hygiene is essential. Depending on the storage conditions addition of suitable preservatives may be necessary. Care must be taken that drums and containers are properly closed. During storage, shipping and handling contact with metal surfaces that are not corrosion protected must be avoided. When stored properly, the product has a shelf life of 12 months from the date of delivery.
