Water-repelling agents

The polymeric acyl titanate esters are viscous Hquids or waxes that are soluble ia hydrocarbon solvents and can be used as Ti02-dispersiag agents, water-repellent agents for textile fabrics, and mst inhibitors for steel. [Pg.141]

Using water repelling agents it is possible to either considerably reduce the viscosity of compositions with a predetermined filler content, or increase the admissible filler concentration for given viscosity [262], In a filled system (e.g. PP + chalk) the treatment of the filler to enhance its polymerophilic properties promotes breakdown of agglomerates [263],...

How far the vapor-treating technique will be extended to building materials, minerals for ore-flotation processes, and other large-scale uses remains to be seen. Since the technique requires only a small amount of material, and since mixed methylchlorosilanes may be used directly without distillation or hydrolysis, the process should be much less expensive than using a coating of silicone resin or oil on the same surface. Used without waste, the methylchlorosilanes may prove even less expensive than the traditional water-repellent agents such as waxes and lacquers. [Pg.88]

PERAPRET VA is compatible with water-repellent agents e.g. the RAMASIT and PERSISTOL types. It may impair the water repellency, particularly when used in high concentrations. [Pg.89]

A particular advantage of TEXAPRET NAV is that it can be combined with water-repellent agents, e.g. the PERISTOL and RAMASIT types. It normally has no influence on the water repellency. [Pg.92]

The PERSISTOL types are supplied in the form of aqueous emulsions. They are wash-resistant water-repelling agents derived from paraffin wax or silicone and are used mainly for the water-repellent finishing of outerwear. [Pg.96]

PERSISTOL E is an emulsifier-free, clrconium salt-containing paraffin wax emulsion, which is used as an all-purpose water-repelling agent. It can be combined with the KAURIT and FIXA-PRET types used in resin finishing. [Pg.96]

The RAMASIT types are water-repelling agents derived from paraffin wax. They are used mainly for finishing tent cloths and canvas and for the after-impregnation of textiles. [Pg.97]

Metallic salt and paraffin wax emulsion with antimicrobial additives. Special water-repellent agent for glass fiber fabrics. Used in combination with SARPIFAN BKF in the stiffening process of glass fiber fabrics. [Pg.589]

PVAc-disperslons, free of plastiziser, for all finishing operations, compatible with anionic and non-ionic softeners, can be combined with water-repellent agents, non-ionic. [Pg.594]

Combination of a polyvinyl dispersion with a water-repellent agent, slip proof finish of glass fabrics for asphalted roof paper. [Pg.594]

Compared with other water-repellent agents, the silicones are distinguished by an especially soft handle and very good permanency in effect after washing and cleaning. [Pg.630]

Naturally, leather absorbs some liquid water but mainly is water resistant. The leather industries do not claim that it is waterproof. So-called waterproof leathers are finished with water repellent agents such as organo-silicon, fluorocarbon and so on. Water absorption of leather can be tested by a static absorption method (ASTM D1815, 2000a). Cut the conditioned specimen with a circular cutter. Measure the diameter and thickness of the specimen. Calculate its volume in cubic centimetres. Weigh the specimen to the nearest 0.01 g. Immerse the specimen in distilled water at 23 1 °C in ahorizontal position with the grain side up. Leave the specimen immersed for a period of 30 min. At the end of immersion, take out the specimen and blot the surface of the specimen with filter paper to remove excess water. Weigh the specimen immediately to the nearest 0.01 g. Calculate the amount of water absorbed by the specimen ... [Pg.65]

Some sorbents are treated with oleophilic (oil-attracting) and hydrophobic (water-repelling) agents to improve the ability of the material to preferentially absorb oil rather than water. As natural sorbents often recover large amounts of water along... [Pg.112]
