How to Ship Parts To SilcoTek For Custom Coating Service

• Customer packaging is only re-used for return shipping upon request.  If, at receipt, incoming packaging is deemed inadequate for secure shipping, SilcoTek will use new packaging to ensure coated parts are returned safely.

• Please be sure to package heavy parts to avoid any part-to-part contact that may result in damage to your parts in transportation.
  
  
• Please inform us of any special handling requirements you may have for your parts.

Your parts go through an aqueous surface preparation step by SilcoTek prior to processing. Additional pre-cleaning by the customer is often unnecessary and at times can be detrimental to our coating process.

In order to provide the highest quality coating and fastest processing; notify SilcoTek of any prior chemical exposure (regardless of whether the part is new or used). Chemicals like cutting oils, pickling acids, solvents, water based cleaning compounds or other hazardous or non hazardous chemicals may impact the coating process. Many times the customer's cleaning process or chemical exposure can be eliminated, saving the customer time and money. Before sending parts to SilcoTek, contact your SilcoTek representative at service@SilcoTek.com or call us at (814) 353-1778

• When cleaning a treated part, rinse with a solvent compatible with the contaminants you intend to remove (i.e., use non-polar solvents with hydrocarbon surface contaminants, more polar solvents with more active contaminants). Do not use basic solutions with pH>8.
• Avoid using cleaners containing abrasives as they can scratch the layer. Mild sonication may assist in contaminant removal, but do not oversonicate—this could damage the layer.
• Avoid steam cleaning of components and lines as this can damage the layer.

SilcoTek® warrants its coatings to be free from defects for a period of ninety (90) days from date of delivery. In the event of a defect, SilcoTek will recoat the parts. In no event will SilcoTek be liable to Customer or any third party for damages greater than the price of the coating.

If SilcoTek is unable to recoat the parts, it will refund the purchase price of said defective coating. This shall be the sole warranty of SilcoTek.

SilcoTek expressly disclaims any other expressed or implied warranties, including but not limited to, the implied warranties of merchant ability and fitness for a particular purpose. SilcoTek shall not be liable for any direct, indirect, special, incidental, or consequential damages of any kind. No oral or written advice or information provided by SilcoTek shall create any warranty. The foregoing states the entire liability of SilcoTek with respect to product warranty.

SilcoTek will not be liable for any loss of use, interruption of business, or any indirect, special incidental, or consequential damages of any kind (including lost profits) regardless of the form of action, whether in contract, tort (including negligence), strict product liability, or otherwise, even if SilcoTek has been advised of the possibility of such damages.

No indemnification required to be provided by SilcoTek pursuant to any agreement with Customer or otherwise shall be deemed to override the foregoing limitations and disclaimers, and the foregoing shall govern in the event of any inconsistency. SilcoTek will not be responsible for the payment of labor for the removal of the defective parts, the transportation or shipping costs incurred in providing or securing the foregoing warranty service, or the payment of labor for the reinstallation of the repaired and/or recoated parts, and Customer must follow SilcoTek's reasonable instructions regarding procedures for returns. The determination of whether its coatings fail to meet specifications or are otherwise defective, as aforesaid, shall be within SilcoTek's reasonable judgment.

Galling can occur when two parts of similar material are connected under compression and the heat generated "cold welds" the parts together. Customers have observed Galling when two Silco'd treated compression fittings or NPT fittings are assembled. For that reason SilcoTek does not recommend coating the nuts or ferrules from compression fittings and recommends that the coating either be removed with an abrasive pad or apply Teflon tape to threads when two NPT fittings are connected.

If both mating parts must be coated, then SilcoTek recommends using anti Seize compounds made from Silver, Moly or Nickel: For sample cylinder applications refer to the instructions pertaining to the use of Teflon tape on the valve NPT prior to installation

Compression fitting nuts and ferrules may leak after coating.  Our Engineering Team have noted the following potential issues when coating nuts and ferrules:

• It has been noted that coated ferrules used in conjunction with coated tubing unions offer the opportunity for a leak due to high shear stress when making the fitting.
• It has been noted that tube sections sent for coating with pre-seated ferrules offer the opportunity for leaks during the coating process.

• Coiled tubing is processed internally only and requires that we attach process leads to each end using standard compression fittings, nuts and ferrules to attain a gas-tight seal. Please allow an extra six inches of tubing on both ends for us for processing and to remove the nuts and ferrules after processing. Tubing ends will be cut with a standard tubing cutter after processing and capped for return shipment.
• Coiled tubing that is processed internally will be returned to you with the outside of the tubing appearing brown. This change in color is due to the processing and is oxidation of the exterior caused by exposure to high temperatures.
• Please send tubing wound on metal spools or bound by wire ties. Do not send tubing wound on wooden spools or bound by plastic ties since they will be damaged or burnt during high temperature processing.

• SilcoTek will coat all stainless steel wetted surfaces of your disassembled valve. Please only send stainless steel components that should be coated.
• Please be sure to remove all Teflon seats or o-rings. Please be sure to protect critical surfaces during transport to SilcoTek.
• Please be sure to check internal cavities for pressed in Teflon seals that need to be removed before coating.
