Surface roughness- a measurement  of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If the deviations are large, the surface is rough, if they are small, the surface is smooth.

Applications:
You can take impressions of:
  • ALL METALS
  • ALL PLASTICS
  • NON METALS
  • RUBBER
  • PAPER OR CARDBOARD ITEMS
  • CERAMIC AND GLASS ITEMS
  • WOOD, MARBLE, ETC.
Other Uses Include:
  • Fixturing where semi-rigid structure is desired.
  • Making joints where flexibility is required.
  • Prototypes of rubber type components such as gaskets, washers, etc.
  • As a mask for high temperature plasma spray of metallic coatings.
Physical Advantages Over the Hard-Copy Replicas:
  • Replica is easy to remove - even if there are under cuts or grooves.
  • Cross-sectioning of replica is easily accomplished with a knife or razor.
  • It can then be checked on an optical comparator or microscope.
  • Surface finish replication is exact with excellent optical properties.
  • Replicas are permanent - will not leach or ooze out nor outgas.
  • NO MORE 16 HOUR CURE TIME AS WITH RTV SILICONES
  • MORE ACURATE THAN ALL OTHER RTV COMPOUNDS
  • REPRORUBBER PUTTY will withstand up to 600oF (or more).
  • Reprorubber copies can be recopied (copy from a “female mould” yields a male-shaped replica). See EPOXY PARFILM ULTRA.

Facsimile

Quick Setting Compound

Makes accurate hard plastic reproduction in 6 - 8 minutes

Facsimile is a special plastic compound kit which is used for duplicating surface flats, roughness and for dimensional transfer of inaccessible locations. Many other applications are listed below and many more in out free 24 page appli-cations booklet.

 

•Make duplicates for measuring, such as gages, etc.

•Test surface geometry, flatness, microfinish, etc.

•Make permanent records of surface geometry, etc.

•Make custom holding and nesting fixtures.

•Make quick jigs.

•Make excellent stylus patterns.

•Make instant mold and patterns.

•Cast small run parts and prototypes.

•Mask, fill in and seal.

•Fretting depth of blade dovetails in jet engines.

•Make potting, bonding and repairing easy.

•Closer inspection can be performed by allowing the casting to cure in a pressure vessel (15 p.s.i.)

•Facsimile will not affect the surface of ferrous or non-ferrous materials to which it is applied.

•When casting in a "CONFINED" area, it is better to cat 1/2 of the internal shape.

•When casting without releasing agent, and ACETONE soak removes Facsimile.

  

TECHNICAL DATA
AVAILABLE IN LARGER "ECONOMY" KITS
A test submitted by E.I. Dupont DeNemour & Company to an independent test lab showed the following properties of Facsimile®:
TEST PIECE APPROXIMATELY 1” BY 1 /4” THICKNESS...
COMPRESSION TEST...Maximum load 6,800 lbs. Compression strength 9,650 PSI.
MECHANICAL PROPERTIES...Ultimate tensile 3,415 PSI.
WATER ABSORPTION...(24 hours at 73 o ) 0.31% by weight.
The kit contains all material and instructions. The Facsimile® can be diluted from a putty consistency to a watery to best suit your job needs. If larger quantities of Facsimile® are desired they can be ordered in 3 lb. and 25lb. kits at proportionately lower prices per pound.

Facsimile® is Made in U.S.A.

APPLICATIONS AND TECHNICAL INFORMATION

SOME OF FACSIMILE'S MANY USES:  
USE #1: To create a master or
checking gage, just pour in facsimile
and wait 6 to 8 minutes. Parts later can be conventionally ground, machined, etc., if desired. Drawing above shows creation of a thread gage.
USE #2: Shown above is a quick and inexpensive method of cre-ating a drill fixture. Just pour facsimile around drill bushings and wait 6 to 8 minutes. Casting must be a thick section 3/8” or more. USE MAGNETS TO HOLD PLATES.USE #3: Without removing work from the machine set-up you can create a “facsimile” test sample which can be carried away for testing. Duplicates from 3 to 1,000 Micro inches perfectly.





USE #6:
Highly accurate and reliable casted replicas of internal thread forms are not only possible but they are being performed daily by fac simile users the world over.
USE #4: Used for checking
radii and angular internal and
external recesses, often in difficult to measure areas.
USE #5: Optical projections
of forms made with “facsimile”
are duplicates within millionths!

NEW-SUPER RELEASE AGENT

EPOXY PARFILM ULTRA
A NEW and Highly Effective Release Agent
for users of Facsimile "measure image".
NON-CFC, NON-VOC Formula.

Epoxy ParFilm is the culmination of a
search for a suitable release agent for
epoxies.

The highly effective, very thin film obtainable from Epoxy ParFilm Release is non-melting and will not carbonize. This makes it suitable for use with exothermic cures, such as Facsimile "measure-image" replication compound.
Epoxy ParFilm offers better release than polyvinyl alcohol and wax with a much thinner film application.

Epoxy ParFilm can be applied quickly with the easily operated directional valve which is standard.

Epoxy ParFilm is non-combustible, non-toxic and non-allergenic. Contains NO CHLORINATED SOLVENTS.
Order No. 16136, Epoxy
ParFilm, 18 ounce spray

QuickSetting Putty

Final Color: Light Blue

Roll two equal balls of catalyst putty and base putty and simply knead them together like dough.

Excellent for external shapes. Simply spread over master pushing down with fingers and wait for cure 8-10 minutes. You have 3 or 4 minutes of manipulation time - Therefore 14 minutes start to finish. You can also cast internal shapes and cavities but some pressure should be applied such as a weighted object on top.
