1. Scope
This specification applies to the requirements of the HEA® or CHEA® coatings, with PrintFree™ option, using the TIGOLD MetaMode™ sputtering deposion process applied to plastic substrates.
Some substrates may have a Pressure Sensitive Adhesive herein referred to as “PSA”.
2. Construction and dimensions
2.1 Construction
Organic PrintFreeTM
HEA® or CHEA®
TIGOLD qualified hard coat
Plastic substrate
PSA layer
Release liner (optional)
2.2 Dimensions
TIGOLD shall coordinate dimensional requirements with each customer product in order to maximize both TIGOLD and customer processing utilization. Maximum size will depend on thickness of substrate. In general for substrates 1.5mm or less, the maximum dimensions are 1080mm x 500mm (1080mm x 480 mm minimum with TIGOLD coating). For substrates thicker than 1.5mm up to 5mm the maximum dimensions are 900mm x 330mm (900mm x 310 mm minimum with TIGOLD coating).
3. Appearance, Spectral Properties, and Durability
3.1 Appearance
3.1.1 Cosmetic quality defects in the MetaMode™ HEA® or CHEA® coatings, with PrintFree™ option, shall be monitored for each product type. A sampling plan for each particular substrate may be developed between TIGOLD and customer.

Coffee
Cola
Ethanol
Felt tip pen

See 4.8 |
4. Test Methods
4.1 Cosmetic Appearance
4.1.1 Visual inspection
Defects (pinholes in the coating) shall be measured visually at a distance of approximately 30cm from the specimen under 30-40 watt cool white fluorescent lights (covered with an opaque white diffuser) so that illumination of approximately 2500 Lux is provided.
4.1.2 Scratch
Inspection for scratches shall be performed visually at a distance of approximately 30cm from the specimen under 30-40 watt cool white fluorescent lights (covered with an opaque white diffuser) so that illumination of approximately 2500 Lux is provided.
4.2 Reflected Luminance (brightness)
The specular reflectance of linear polarizers and other substrates coated with HEA® or CHEA® coatings, with PrintFree™ option, shall be measured at a 10ş incident angle from the normal. The specular reflected luminance (reflectance weighted by the photopic eye response and the illuminant) shall be calculated from the measured reflectance. Illuminant C shall be used as the weighted light source.
4.3 Reflected Color
The reflected color of substrates coated with HEA® or CHEA® coatings, with PrintFree™ option, shall be calculated from the measured reflectance using a 1931 xy CIE Color Coordinate system with a 2ş observer and an illuminant C light source.
4.35 Resistivity
4.4 Adhesion
For Flexible Plastic Films and Linear Polarizers coupons, approximately 30mm wide, may be submitted to test from different areas at one edge of one sheet per run. Samples will be used for testing adhesion, boil, rub durability and contact angle verification. Rigid substrates may use coupons (approx. 75mm x 150mm) for adhesion testing. These coupons will be representative of specific areas of whole coated sheet. The samples of the coating shall show no evidence of delamination from the hard coated surface of the substrate. The backside (adhesive side) of the #600 tape and the area of the substrate that was tape tested shall be examined for evidence of coating material. The coated surface of Linear Polarizer will be cross-hatched prior to tape testing with a razor knife to produce 2mm square pattern on the coupon.
4.5 Pen Cleanability
After PrintFree™ HEA® or CHEA® coatings, the pen shall leave no visible pen mark when wiped with a class 100 clean room compatible wiper.
4.6 Contact Angle
The contact angle of a drop of distilled water measured on PrintFree™ HEA® or CHEA® will be 110 degrees or greater. The measurement device is a Kruss G10 Contact Angle Measuring Instrument.
4.7 Abrasion
After boil test, the coating shall show no evidence of permanent deterioration when viewed from a distance of approximately 30cm from the specimen under 30-40 watt cool white fluorescent lights (covered with an opaque white diffuser) so that illumination of approximately 2500 Lux is provided.
4.8 Chemical resistance
The coating shall show no deterioration after a puddle of each of the agents is allowed to remain on the surface for 24 hours. Chemical agents which can only be removed by acetone will not be considered for testing as this would destroy the plastic substrate.
5. Incoming Inspection for (CFM) Customer Furnished Material to be coated
5.1 Definition of Lot
One lot shall consist of the identifiable product of the same type manufactured continuously from the same materials under the same manufacturing condition.
5.2 Manner of Inspection by TIGOLD
Samples from each lot will be brought to a Class 1000 staging area. These will be reviewed for cleanliness before entry into cleanroom.
6. Packaging and Marking
6.1 Packaging TIGOLD to customer
Methods of packaging and marking materials for shipment should be determined for particular types of products. Appropriate interleaving (typically white Tyvek interleaving) will be used. TIGOLD will attempt to recycle any CFM packaging where appropriate.
6.2 Marking
The product shall be legibly identified by TIGOLD to customer with the following information:
< Customer Name
< Product Name
< Customer Purchase Order
< Run #
< Quantity
< Other identifiables as agreed
6.3 Quality Data and Reports. These issues should be determined separately for each customer. Production history of material can be generated to customer needs.
6.3.1 If any portion of the substrate is defective, it may be marked by customer’s request. The marks will show which portion of the sheet is defective. The method of marking may be determined by mutual agreement between TIGOLD and customer.
Supplemental item:
For TIGOLD to ensure that deposition of the HEA® or CHEA® coatings, with PrintFree™ option on a new type of plastic substrate, the substrate will be qualified as a production process to the requirements of this specification. A minimum quantity of full production coating batches in the MetaMode™ machine is required to prove capability. Customer samples may be produced and tested by both the customer and TIGOLD, but until full coating batches are produced and capability established for a particular substrate/coating package, this specification is for testing purpose only.
If Parties desire a modification to this specification both parties must agree in advance.
