Whilst dissolving MARLINAT 242/90 M in water, a gel forms at the 30-80 % range of concentration which refers to the active matter. This phase can be overcome by using suitable methods of solution or agitators.
a) The product should be dissolved in up to +30 °C warmed water under agitation conditions. It is advisable to firstly warm the water and then add the MARLINAT 242/90 M which has been finaly dispersed for example by means of a spray pipe. Pumping with a rotatory pump assists the mixing process.
b) Dilution facilities in the plant, which present the best and most economical solution when material is purchased in bulk quantities, work as follows: The required amounts of MARLINAT 242/90 M and water are transferred via separate pumps into a mixing chamber where they are homogenized using high-speed agitators. Such in-line machines achieve high cutting powers so that gel phase is quickly passed through producing clear solutions.

Technical Details & Test Data
- Additional Information
At + 20 °C MARLINAT 242/90 M is an homogeneous and pourable paste with a newtonian viscosity behavior. The product is delivered in 1 m3 containers or in plastic drums.
Extraction
To extract the material, it is advisable to use reciprocating and rotating pumps. It is important that the cross-section of the pipes is large enough and that the distance to the storage tanks is not too long. Right-angled pipes should be avoided. The pipes should be insulated and heatable with water.

Storage Conditions
- MARLINAT 242/90 M should be stored at +20 °C as at lower temperatures its viscosity is very high and therefore its pumpability strongly decreases. At temperatures lower than + 15 °C the viscosity of MARLINAT 242/90 M is so high, that it is not pumpable anymore. This must be particularly taken into consideration when MARLINAT 242/90 M is storaged in drums or containers at temperatures below + 20 °C.
- Long term storage temperatures should not exceed +40°C. A careful short term warming to max. +50°C is possible. Only warm water of max. + 50°C should be used as medium for heating. The use of hot steam to warm up the material is absolutely prohibited. The hydrolysis and therefore the decomposition of MARLINAT 242/90 M is catalyzed under the influence of acids, whereby this exothermic reaction also heats the product and therefore, the speed at which the product decomposes, increases further. The hydrolysis, caused by local overheating or acidification, continues rapidly as the process is autocatalytic. The autocatalytic decomposition can be avoided by keeping the pH constant at 6 - 8.
Storage Tanks
- MARLINAT 242/90 M can be stored in Chromium-Nickel-Steel V2A (no. 1.4571), V.A (no. 1.4541) tanks as well as in chemical and stress stable plastic tanks with a conical or rippled base. To guarantee storage temperatures of at least + 20 °C, the tanks should be heatable. To avoid local overheating (risk of hydrolysis!) it is advisable to use storage tanks equipped with a jacket heating in which warmed water (up to +30 °C, not steam) can be circulated.
- It is furthermore advisable to slowly stir the product from time to time (with a slowly running agitator) to ensure that the temperature is well-distributed. Mixers which are leaf-shaped have proven to be most effective. To avoid the incorporation of air bubbles, the product should be filled into the storage tanks through a pipe which ends just above the tank base.
