Definitions
- the present invention relates to a composition comprising an OH component and an NCO component.
- the invention also relates to the use of the composition for the preparation of resin, in particular for use in a filtration module, for example in the field of treatment of water or aqueous effluents.
- Potting resins are known in many fields, in particular in the field of filtration of effluents such as water. They can be compositions with one or two components which are applied in the liquid state and then crosslink either at room temperature or under the effect of heat, to form a polymer (resin).
- Epoxy resins are commonly used as potting resins in the field of water filtration. These resins have the following advantages: Newtonian behavior, transparency, absence of foaming because they do not react with water.
- the main disadvantages of epoxy resins are that they are rigid brittle products, sensitive to aging and / or to chemical resistance.
- their high capillarity during casting can generate a containing meniscus (because rigid) which can be detrimental to the longevity of the membrane (in particular during the cleaning / reverse circulation phases, pressure surges).
- polyurethane resins used as potting resin.
- this type of adhesive is subject to staining, can lead to high exothermic temperatures (and lead to the degradation of the filtration fibers), and can be highly sensitive to humidity possibly leading to the formation of foam (emission C02) after contact with water.
- the reaction with water can generate molecules of low molecular weight that can migrate into drinking water.
- Some polyurethane resins are not transparent, which does not allow the quality of the potting to be checked (absence of bubbles, cavities, etc.), this most often results from the addition of desiccant (s) which, in addition to adversely alter the rheology of the resin, making it opaque.
- the hydroxyl number of an alcoholic compound represents the number of hydroxyl functions per gram of product, which is expressed in the form of the equivalent number of milligrams of potassium hydroxide (KOH) used in the determination of hydroxyl functions, per gram of product;
- the viscosity measurement at 23 ° C. can be carried out using a Brookfield viscometer according to the ISO 2555 standard. Typically, the measurement carried out at 23 ° C. can be carried out using a Brookfield RVT viscometer, a needle adapted to the viscosity range and at a rotation speed of 20 revolutions per minute (rpm).
- the viscosity of a product is preferably measured at least 24 hours after manufacture of said product;
