# Klüber Klübertop TP 41 N A/B Komp. A

Klüber Klübertop TP 41 N A/B Komp. A is a  two-component bonded coating for metal components

– Long component life expectancy
– for a wide service temperature range
– especially in combination with oils or greases
– due to a highly flexible bonded coating
– coatings of up to 70 µm thickness can be applied
– Better component performance
– due to less stick-slip
– due to very high resistance to wear
– as lifetime lubrication is possible

#### Description

Klübertop TP 41 N A/B is a thermosetting, black-coloured highperformance bonded coating made up of two component parts. It has an organic binder containing PTFE-free solid lubricants. Klübertop TP 41 N A/B reduces friction and wear on metal/ metal and metal/plastic material pairings. This bonded coating can be used for high mechano-dynamic loads as well as with high temperatures. Optimum performance of the bonded coating is obtained with low to medium surface pressures.Klübertop TP 41 N A/B is supplied in liquid form and with a viscosity ready to use. It contains an inflammable solvent mixture (former hazard class A II ). Once applied and hardened, the bonded coating forms a dry lubricating layer with a wide service temperature range, low friction coefficients and a high resistance to wear. Its resistance to chemicals and anticorrosive effect are good. Klübertop TP 41 N A/B excels due to its excellent high wear resistance plus good adhesion on steel and aluminium substrates.

#### Application

Klübertop TP 41 N A/B is used with components that require a low friction coefficient but where contamination by oil or grease is highly undesirable. Typical applications are found, for example, in the automotive industry or in electrical and precision engineering.
Due to its good resistance to media and wear, Klübertop TP 41 N A/B is also particularly suitable for dynamic loads when used in combination with oil lubrication. The mixture is applied to the component by means of spraying. The recommended layer thickness for tribological loads is 5 to 25 µm (dried coating). For special applications, layers up to 70 µm thickness may be applied. For application by means of spray systems, we recommend a stirrer to be installed in the mixture container and circulating mixture feed. This helps to prevent the solid lubricants from settling. Please ensure that the relative atmospheric humidity is fairly low (max. 60 %) during application processes (coating and deaeriation). If atmospheric humidity is too high, water will be absorbed into the wet applied film (product is hygroscopic). This may impair the lubricating film’s performance, especially if the coating is applied wet-on-wet. To clean the spray equipment and dilute the bonded coating, the Klüber solvent and cleaning agent SOLUTIN C 10 (Art. No. 058036) may be used. Opened containers of both components should be closed again immediately after use

#### Application notes

Klübertop TP 41 N A/B consists of:

Component A (Art. No. 099202) and component B. Klübertop TH 06 component B (Art. No. 099200) is used as component B. Component B is mixed with component A at a 5 wt. % to 95 wt. % ratio.

Example: 50 g of component B with 950 g of component A.

Prior to mixing the components, stir component A to remove any bottom deposits. Use a slow-moving stirrer (500 to 800
rpm, stir for at least 15 min) or a high-speed jetstream stirrer, e.g. made by Ystral, drive x 40/36, shaft LDT-1, mix-ing generator Ø 65 mm (approx. 10 000 rpm, stir for 5 min). Upon stirring, add component B. The mixture should be homogenised either by the above-mentioned slow-moving stirrer for 15 min, or by the high-speed jetstream stirrer for 5 min. If the high-speed stirrer is used, make sure the temperature of the mixture does not significantly exceed 30 °C in order to avoid drop in viscosity (reversible), which would
increase the tendency of the bonded coating to drip off the component After mixing, pass the mixture through a poly-ethylene filter with approx. 150 µm pore size. The mixing container should always be covered with a lid. The mixture of components A and B can be processed for approx. 24 h provided the ambient temperature is not much above 25 °C (pot life). As the bonded coating shows thixotrope properties, it should be stirred up after an ex-tended period of non-use (> 12 hours) in order to re-establish its original
viscosity (5 minutes at approx. 500 rpm is sufficient). Any tubes in contact with the mixture must be made of polyethylene or PTFE.

When subjected to a heat treatment of 100 °C the coated parts are dry to the touch after approx. 6 – 10 minutes. To obtain a
bubble-free coating, especially when its thickness is > 15 µm, the coated component should be allowed to deaerate for 10 to 15 min at a temperature between 80 °C and 120 °C prior to hardening at 230 °C.
