REVACRYL AE 4625

REVACRYL AE 4625 is a finely dispersed, aqueous dispersion of a styrene-acrylic ester copolymer. The dispersion contains an anionic emulsifier system and is free from film forming aids, solvents, plasticizers and ammonia.



Technical Informations

Application Advice/Typical Applications

REVACRYL AE 4625 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 4625 forms a clear, tack-free, and water-resistant film. The film is characterized by good light, ageing and saponification stability. Owing to it´s low odour (ammonia-free) the dispersion is particularly suitable for internal applications and in industrial manufacturing processes. Primary applications are: paint materials for inside / outside use, pasty building and tile adhesives, high-grade plasters, additive for silicate paints, and priming of mineral substrates. Pigmentation / wetting agents: REVACRYL AE 4625 shows good compatibility with the generally used pigments and fillers. In the case of a very high PVC and the use of fillers with a large specific surface, the requirement for wetting agent should be determined. Dispersing agents such as SER-AD® FX 605, Pigmentverteiler N and DISPEX® N 40 in combination with polyphosphates are effective. Thickening: 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, SER-AD® FX 1010), COLLACRAL® VL and inorganic thickening agents (BENTONE® EW) is recommended. Film formation: The film forming temperature can be lowered by the addition of effective solvents. High boiling solvents such as SER-AD® FX 511, LUSOLVAN® FBH or diverse DOWANOL® grades are highly active, white spirits containing aromatics (boiling point 180 - 220 °C) and butyl glycol have a lesser activity and must be used in higher dosage. Defoaming: For the production of dispersion paints and plasters defoaming agents like SERDAS® GBR, AGITAN® 218/281, BYK®-034, DEHYDRAN® 1620 are suitable.
