Durakote SK-33
Brands:
Types:
Field of application:
Introduction:Durakote SK-33 is a new mold release agent that matches the environmental regulations.
1. Features
(1) Good release performance with fluorocarbon as the ingredient.
Highly precise release performance can be obtained with a thin film.
(2) The composition complies with the regulations on environmental burden substances such as PFOA
and ozone-depleting substances.
(3) Being a silicone-free type, it is suitable especially for molding of electronic and electric parts.
(4) Forms a dry coating with little transferal to the molded item, preventing it from becoming sticky.
(5) Prevents molds from becoming contaminated, reducing the number of mold cleaning cycles and
improving productivity.
2. Properties
(1) Appearance Semi-transparent liquid
(2) Specific gravity 1.01 (at 25°C)
(3) Density of solid component 3 mass %
(4) Principal solvent Water
(5) Recommended dilution multiples 10 – 15 times
(6) Hazardous material classification Non hazardous material
(7) Diluting solvent Water (tap water, ion-exchange water)
3. Scope of application
Rubbers: SBR, NBR, EPDM, CR, U, FKM, etc.
Thermosetting resins: Epoxy, Non-saturated Polyester, Phenol resin, etc.
Thermoplastic resins: PE, PP, PVC, PS, ABS, PA, POM, PC, etc.
4. Method of use
4-1 Dilution Use the mold release agent straight or dilute with water (desirably ion-exchange water) appropriately, and agitate it until uniformly mixed.
Part of the ingredients may settle out. In that case, agitate the mold release agent well before use. If diluted, finish up the product immediately. Avoid long storage of dilute solution.
4-2 Application Before using the product for the first time, remove the old mold release agent completely.
Apply a uniform coating film using an air spray device, brush, or rag.
When spraying on a mold, desirably spray the mold release agent lightly a few times.
It is more effective to apply a few thin coating films of low concentration of the agent than to apply one thick coating film of high concentration of the agent.
Be sure to use an appropriate amount of the agent since use of an excessive amount may result in mold contamination.
4-3 Cleaning the mold Slight contamination or the mold release agent can usually be removed to a certain degree by wiping with a solvent (IPA, toluene, acetone, etc.). Alkaline cleaning agents are effective for complete removal. (Immerse in an approx. 10% aqueous solution of potassium hydroxide or sodium hydroxide to which a small amount of surface active agent has been added. The cleaning solution should be at a temperature of 60–80°C.)
5. Usable temperature range
Room temperature to 200 °C
6. Cautions on handling
(1) Be sure to read the Material Safety Data Sheet (MSDS) and precautions on the label before using
this product.
(2) Do not use this product for other than industrial purposes.
(3) Store in a cool and dark place. Avoid long time storage at a temperature over 40°C.
