17. Product- SurTec® 101 Sprayable Immersion Cleaner

Properties

liquid cleaner for all materials
sprayable above 40°C
suitable for iron and steel, copper and brass, aluminium and zinc
partially suitable for magnesium (depending on the respective alloy)
suitable for hard water
quickly demulsifying
with temporary corrosion protection

Application
SurTec 101 is applied in immersion-, ultrasound-, spray- and injection flood wash lines for cleaning and passivating.

make-up value:	2.5 %vol	(1-4 %vol)
temperature:	60°C	(40-80°C)
application time:	5 min	(1-10 min)

Technical Specification

(at 20°C)	Appearance	Density (g/ml)	pH-value (conc.)
SurTec 101	liquid, colourless-yellow	1.057 (1.05-1.07)	approx. 8.3

Maintenance and Analysis
Analyse and adjust the concentration of SurTec 101 regularly.

Sample Preparation
Take a sample at a homogeneously mixed position. Let it cool down to room temperature. If the sample is turbid, let the turbidity settle down and decant or filter the solution.

SurTec 101 – Analysis by Titration

reagents:	0.1 N hydrochloric or sulfuric acid indicator: methyl orange solution (0.04 %)
procedure:	1. Pipette 20 ml bath sample into a 250 ml Erlenmeyer flask. 2. Dilute with deionised water to approx. 100 ml. 3. Add 3 drops of indicator. 4. Titrate with 0.1 N acid from yellow to red.
calculation:	consumption in ml · 0.45 = %vol SurTec 101

Ingredients

nonionic surfactants
amines
neutralized organic acids

Stock Keeping
In order to prevent delays in the production process, per 1,000 l bath the following amount should be kept in stock: SurTec 101 25 kg
