TITLE URETHANE ADHESIVE SEALANT FOR FIXED GLASS INSTALLATION
This bulletin is a supplement to the previous 1986 Windshield Installation Procedure TSB, body number 032, Volume VIII, dated 08-22-86.
In order to comply with FMVSS 212 - Windshield Retention and FMVSS 216 - Roof Crush Resistance, the factory uses a Urethane adhesive sealant with bonded strength of not less than 40 kilograms per square centimeter or 569 pounds per square inch for certain bonded windshields and repair windows on Toyota vehicles.
A Urethane adhesive sealant of at least equivalent strength must be used to maintain these retention and roof crush standards when windshield glass replacements are performed by either the dealer or an outside glass shop.
Since the adhesive kits listed in Toyota Repair Manuals are not available in the USA, this bulletin is prepared in order to supply information regarding locally available equivalent materials. (See Note 3 on page 3.)
For more detailed application information, see the attached "Urethane Adhesive Sealant Applications for Toyota Models".
Be sure to follow the sealant manufacturer's instructions for best results.
Note: Rear Quarter windows on some models are bonded, however, the adhesive for these windows requires less bonding strength and therefore use of Butyl sealer is sufficient.
This bulletin is for information and clarification only. Existing Warranty policy and Flat Rate information have not been changed. Toyota is not responsible for problems that occur from usage of improper sealants that fail to meet Toyota specifications.
URETHANE ADHESIVE SEALANT APPLICATION FOR TOYOTA MODELS
Note: (1) All others that are not indicated use a conventional weatherstrip method.
(2) The following urethane adhesive kits described in Toyota Repair Manuals are not available in the USA.

(3) Locally available adhesives known to TMS/USA to date are:
^ CUS Urethane Auto Glass Sealer by American Sure Seal Bonding strength = 600 pounds per square in. (approximate)
^ Super Fast Urethane by 3M Bonding strength = 1000 pounds per square in. (approximate)
^ Unrest 212 by Kent Industries Bonding strength = 600 pounds per square in. (approximate)
^ Urethane E Auto Glass Sealer by Protective Treatment Inc. Bonding strength = 600 pounds per square in. (approximate)
(4) Quarter window replacement does not necessarily require the bonding strength provided by the above sealants. Use of butyl sealer is therefore sufficient for these windows.
