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

REVACRYL AE 4522 is supplied in road tankers or in non-returnable plastics drums secured by a lid with clamping ring or in non-returnable palletized bulk containers (net weight 1,000 kg). REVACRYL AE 4522 has to be stored protected from frost and, as far as possible, below 40 °C. Storage at temperatures between + 5 and + 30 °C is recommendable. REVACRYL AE 4522 contains a preservative to counter microbial attack during transportation. To protect it against germination during storage, absolutely stringent plant hygiene and, under certain circumstances, the addition of suitable preservatives will be necessary. Care must be taken to ensure that drums and storage containers are tightly closed. During processing, storage and transport of the product contact with metals unprotected against corrosion (likewise non ferrous metals) has to be avoided. When stored correctly REVACRYL AE 4522 has a storage life of 12 months from date of delivery.
