Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a binder for oriented strandboards (OSB) and waferboards in accordance with the conditions and limitations stated in this evaluation, complies with the following code:

National Building Code of Canada 2015

Code provision Solution type
9.23.15.2. Material StandardsAlternative
9.23.16.2. Material StandardsAlternative
9.23.17.2. Thickness, Rating and Material StandardsAlternative
9.27.10.1. Material StandardAlternative
9.29.9.1. Material StandardAlternative
9.30.2.2. Materials and ThicknessAlternative

The above opinion is based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.

Product information

Product name:

Rubinate® 1840

Product description

The product is a binder made from polymeric diphenylmethane diisocyanate (PMDI) used for the manufacturing of waferboard and OSB. PMDI is produced from aniline and formaldehyde reacting together using hydrochloric acid as a catalyst. The reaction produces a complex mixture of polyamines, which are phosgenated to obtain a polyisocyanate mixture. All raw materials react completely during the process.

Manufacturing plant

This certification is valid only for products produced at the following plant:

  • Geismar, Louisiana, United States

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product may be used for the bonding of strands in the manufacturing of OSB products that are intended to conform to the requirements of CSA O437.0-93, “Standard on OSB and Waferboard” as referenced in CSA O325-07, "Construction Sheathing.”
  • Each finished wood product (e.g., OSB panel) that uses Rubinate® 1840 must conform to CSA O325-07.

  Technical information

This evaluation is based on demonstrated conformance with the following criteria:

Administrative information

Disclaimer

This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:
