FLUOROSILICONE DISPERSION IN PCE/BA, IMPLANT GRADE
|
|
DESCRIPTION
Applied’s Implant Grade Fluorosilicone Dispersion PN 40130 is
perchlorethane-butylacetate, dimethyl methyltrifluoropropyl copolymer silicone
dispersion designed for use in fabrication of membranes with altered
permeability. This product was formally ASC Part Number 40032,
Fluorosilicone Dispersion in 1,1,1 Trichloroethane and is equivalent to ASC Part
Number 40038, Fluorosilicone Elastomer, Medical Grade. Elastic silicone membranes of virtually any shape can be
fabricated.
A membrane is generally formed by coating
processes such as dipping, casting, spraying, knife coating, or brushing.
After evaporation of the solvent, the silicone is cured by application of heat
and a strong, elastic membrane is formed.
This product is supplied either as a one-part,
ready to be used catalyzed dispersion, or as a two-part product (silicone-solvent
mixture) and a silicone cross-linking compound.
This dispersion is designed to exhibit high
thixotropy providing exceptional build at low processing viscosities. |

BIOCOMPATIBILITY
This material is intended for long term medical
contact or implantation. Manufacturing of this material is performed under
stringent quality control that is fully traceable per ISO 9001.
Applied Silicone recommends that product
designers using this material contact Applied Silicone Corporation's Regulatory
Affairs to determine what test results are available before incorporating this
material into a medical device. the user of this material must
independently determine that any medical product incorporating this material is
safe and effective. |

APPLICATIONS
The one-part product is shipped ready to
use. For the two part-system, the recommended ratio mixture is is 2.7
grams of crosslinker per 1000 grams of 18% solids (1.5 parts crosslinker per 100
parts solids). The use of improper solvent mixtures may lead to partial
insolubility and coagulation of dispersion. Dilute in 95% PCE and 5% BA,
if necessary. The dispersion-crosslinker mixture can then be applied to a mold
or substrate.
When multiple coats are applied, most of the
solvent should be evaporated before a subsequent coat is applied.
Typically, rapid air circulation readily removes solvent vapors. The
ambient temperature should not exceed 30°C to prevent bubbling. High
humidity combined with evaporative cooling can lead to water condensation at the
surface.
After the last coat is applied and most of the
solvent has evaporated, the material is cured by application of heat. Time
and temperature requirements will be dependent on the particular application and
should be determined by the user. As a guideline, thirty minutes at 130°C
is recommended. |

PRECAUTIONS
A Material Safety Data Sheet
(MSDS) is supplied with the shipment. The dispersion contains the solvent
perchloroethylene which a health hazard. The dispersion
should not come into contact with eyes, skin, or clothing. Care must be
taken to limit employee exposure to solvent vapors. Use dispersion with adequate
ventilation. Keep away from open flame, sources of sparks and heat.
When transferring dispersion, ground all vessels. The user is urged to be
familiar with the properties of perchloroethylene and butyl acetate. Since
contamination can result in an unreliable cure, it is important to avoid
contamination of the product, any containers which hold it, and any material to which it is
applied. Certain materials such as tin, sulfur and amine compounds will
cause inhibition or neutralization of the curing agent. Never use latex
gloves to handle this material. |
