SAE Adhesives and Sealants Committee

A meeting was held for the SAE Adhesives and Sealants Committee on January 17 via Webex/teleconference.

The primary goal of this committee is to develop and maintain standards, including test methods, guides, and specifications, for adhesives and sealants used in the ground vehicle segment of the transportation industry. SAE has three levels of these documents - “SAE Standards” with the most rigorous process, “SAE Recommended Practices” for guidelines, and “SAE Information Reports” which only require one level of approval. A secondary goal is educational. Historically this committee has sponsored a day of talks on adhesives and sealants and related topics at the annual “SAE Congress” held in Detroit, Michigan. It is our intent to do this again.

SAE membership is not a requirement to be a member of this committee, although it is encouraged. Members can be anyone interested with expertise to contribute, such as material engineers and manufacturing engineers from the OEMs (original equipment manufacturers), material suppliers for adhesives and sealants, meter/mix and pumping equipment suppliers, researchers from industry, academia, and government, raw material suppliers, and even some general interest retirees. Members do not vote as representatives of their affiliation, but as individuals. The SAE Adhesives and Sealants Committee is very interested in expanding the current membership. As announced in this meeting, a new Chairperson is also being sought.

This Committee currently has responsibility for about 25 standards, 3 of them cancelled and a couple more that will probably be cancelled. Only two standards are specifications, and the plan is to cancel one of them since it hasn’t been updated in over 50 years. It is entitled “Synthetic Resin Plastic Sealers, Non-Dripping Type”, SAE J250. The Committee is not aware of anyone currently using this standard. If it is in use, please contact me. There are alternatives to cancellation. Optimally, the standard would be revised and relevant current technology and information included. Or, if the standard is needed “as is”, SAE has a “stabilization” process that republishes it with the caveat that there are no changes and will be none.  The other specification, SAE J671 “Vibration Damping Materials and Underbody Coatings” is also being reviewed for current relevance.

Another standard, SAE J243 “Methods of Test for Automotive-Type Sealers, Adhesives, & Deadeners”, is currently planned for cancellation, but with replacements. This is a very large document containing several tests used in evaluating adhesives and sealers. The goal is to publish the individual test methods as separate documents, where still relevant, and eliminate of few of the tests that are no longer in use. This should make future maintenance of these standards simpler.

Other standards under review include tests for metal bonding, glass bonding, plastic bonding, and trim bonding. There are even tests for cure processes, such as induction curing, and for accelerated environmental exposure testing.

The SAE Adhesives and Sealants Committee is involved in more than just the maintenance of existing standards. There are additional standards that are in the process of being written for glass bonding tests. Another area of interest would be test(s) that would better simulate application processing in the plant.

We plan on having our next Committee meeting in April.  In the meantime, we will have working meetings to continue the efforts to get existing standards up-to-date and the new draft standards published. The next working meeting is planned for February 14, where we will review the progress on SAE J243, SAE J1525 “Lap Shear Tests for Automotive Type Adhesives for Fiber Reinforced Plastics Bonding” – in ballot, SAE J1553 “Cross Peel Test for Automotive Type Adhesives for Fiber Reinforced Plastic Bonding”, the three glass bonding standards in draft, and others, time permitting.
