The product is an emulsion polymer isocyanate (EPI) adhesive supplied as a two-part system. The resin, G-3270, consists of a water-based polymer in liquid form. The crosslinker, G-2959M, is modified diphenylmethane diisocyanate (MDI), also in liquid form. The two components must be mixed immediately before use following the manufacturer’s instructions. The required mixing ratio is 100 parts G-3270 to 18 parts G-2959M by weight. Standard conformance for this product was demonstrated for softwoods.
This adhesive is intended for bonding solid wood materials in structural wood products designed for exterior applications as specified in the Standard CSA O112.9-10. Depending on the end products, other requirements for adhesive may apply.
This evaluation is limited to products produced at the following plant(s):
- Dorval, Québec, Canada
This evaluation is based on demonstrated conformance with the following criteria:

|CSA O112.9-10||Evaluation of Adhesives for Structural Wood Products (Exterior Exposure)|
This evaluation is issued by the Canadian Construction Materials Centre (CCMC), 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of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue.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:
