Application Advice/Typical Applications

REVACRYL AE 4620 JA 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 4620 JA forms a clear, tack-free and water resistant film. The film is characterized by good light, ageing and alkali resistance. REVACRYL AE 4620 JA has good all-round properties. The dispersion possesses an excellent pigment binding capability and good pigment and filler compatibility. Primary applications are: paint materials for inside and outside use, pasty building and tile adhesives, high-grade plasters, additive for silicate paints, and priming of mineral substrates. Pigmentation / wetting agents: REVACRYL AE 4620 JA 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 like NUOSPERSE® FX 504, Pigment Dispersant A (or 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, RHEOLATE® 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 DAPRO® 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: During paint production effective defoaming is necessary. For this the following products are recommended: DAPRO® GBR, AGITAN® 218/281, BYK®-034, DEHYDRAN® 1620

Shipping and Storage

REVACRYL AE 4620 JA 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 4620 JA has to be stored protected from frost and, as far as possible, at temperatures between + 5 and + 30 °C. One-sided warming (sun, heating) should be avoided. REVACRYL AE 4620 JA contains a preservative to counter microbial attack during transportation. To protect it against germination during subsequent 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 (like wise non ferrous metals) has to be avoided. When stored correctly REVACRYL AE 4620 JA has a storage life of 12 months from date of delivery. REVACRYL AE 4620 JA is only sold in MEA.
