a well ventilated area. Rotate stock.
• Shelf life expires 1 year from manufacture date.
• Agitation may be required if product thickens.
General Use Instructions
• Ensure surfaces are clean and dry and all substrates are
acclimated together at or above 65˚F. Bond at 70˚F or warmer.
• May be applied by squeeze bottle

a minimum of one hour before machining.
Certificates/Listings
Wilsonart Type II is approved for use in the assembly of up to 90 minute fire doors
using the proprietary care material specifications of the following companies:
MARSHFIELD DOOR SYSTEMS, INC. and GEORGIA-PACIFIC. Wilsonart Type
II is listed by Underwriters Laboratories as an approved component in a Class 1/A
fire rated assembly (UL Files R5434 and R6838). For further questions, consult

Hot or Cold Press High Pressure Decorative Laminating
• Ensure laminate and substrate have acclimated to the same
temperature before bonding.
• Use correct roller groove configuration (Black Bros. A2158) with
minimum of 16 grooves/inch and no cross groove. Dual durom-
eter rollers enhance coverage on uneven substrates.
• Apply 6-8 wet mils evenly across substrate.
• Open time is 5 minutes, and closed time is 20 minutes.
• Allow at least a 30 minute cold press time at 70˚F, 45% RH and
40-50 psi. Allow 1-2 hour press time for less than ideal conditions.
• Full cure develops in 24 hours.
• Delay machining for 12 hours after bonding.
• Hot press at 180˚F-200˚F for 60-90 seconds. Machining is
possible after cool to touch.
