What are your requirements. Touchstone Research Laboratory, Ltd. After drying or curing the d22 panels are bent over a mandrel and the resistance to cracking of the coating is determined. Looking for a specific close-up? In one test method, the coated panels are bent over a conical mandrel.
A mandrel bender is commonly used to test for paint flexibility. Paint and Coatings Formability Testing Conical Mandrel Bend Tester Touchstone offers many tests to evaluate the formability of painted or otherwise coated metal products. Request a Free Quote Right Now. Precision cut conical mandrel for accurate results. Built-in ruler for convenient measurement. The degree of bending or deformation of the coated surface is measured to assess the coating flexibility The varying mandrel diameter 3.
The coating materials to be tested are applied at a uniform thickness to panels of sheet metal or rubber-type materials. Right-click to open the PDF in a new window or download it: It is explained in more detail below.
It is used to evaluate paint adhesion on light gage metal. General Use laboratory apparatus balances, baths, blenders, asgm, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Conical Mandrel Bend Tester.
Of Sample Size xmm ASTM D contains two test methods which are used to determine the flexibility or resistance to cracking of organic coatings on substrates of sheet metal or rubber-type materials. A common test is bending a coated panel over a cylindrical or conical shaped bar.
Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, Touchstone offers many tests to evaluate the formability of painted or otherwise coated dd products. In the other, the coated panels are bent over cylindrical mandrels of various diameters. Coatings attached to substrates are elongated when the substrates are bent during the manufacture of articles or when the articles are abused in service.
Special sample holder plate design to prevent panel slippage. Durable design for long term use — Aluminum panels up to Enter product namemake or model.
