CSA O112 SERIES-M1977 (R2006)

1 Scope

O112.0-1.1

This Standard contains certain standard test procedures and general requirements relating to the evaluation of wood adhesives in conformance with the O112-M Series of CSA Standards for Wood Adhesives. This Standard does not include special test methods which are peculiar to a particular adhesive and which are included in the appropriate material Standard.

O112.1-1.1

This Standard covers animal glues used for the bonding of wood for general woodworking applications such as veneering, assembly gluing, edge gluing and other similar applications.

Note: For proper application, the manufacturer’s instructions should be followed regarding preparation, application, and use of these glues.

O112.2-1.1

Scope 1.1.1

This Standard covers starch glues intended for veneering and general wood bonding where moisture resistance of the glue bonds is not a requirement.

1.1.2

This Standard does not cover gums, mucilages, and pastes which are for other purposes.

1.2

Classification Starch glues shall be supplied in one of the following types or forms: (a) Type I – Dry powder form: (i) Processed starch materials; (ii) Natural starch materials; or (b) Type II – Liquid form.

Note: For proper application, the manufacturer’s instructions should be followed regarding preparation, application, and use of these glues.

O112.3-1.1

Scope This Standard covers casein glues used for the bonding of wood or for the bonding of wood and some non-wood materials to wood.

1.2

Classification 1.2.1

Form of Glue The glue shall be furnished as a homogeneous, dry powder.

1.2.2

Types The glue shall be one of the following types: (a) Type I – Intended for use where a bond with resistance to moisture and to micro-organisms is required; (b) Type II – Intended for use where a bond with resistance to moisture only is required; or (c) Type III – Intended for use where low staining characteristics are required, and where moisture resistance is not a requirement.

Note: The proper application of these glues requires the maintenance of adequate pressure in conjunction with suitable temperature and humidity conditions for a sufficient time to permit the glue to set. For proper application, the manufacturer’s instructions should be followed regarding preparation , application, and use of these glues.

O112.4-1.1

Scope This Standard covers polyvinyl resin adhesives for use in the manufactu re of wood furniture and in other wood assemblies, and for the bonding of wood and some non-wood materials to wood, where high moisture resistance of the bond is not a requirement.

1.2

Classification Polyvinyl acetate resin emulsion adhesives shall be furnished in one type only – liquid.

Note: For proper application, the manufacturer’s instructions should be followed regarding preparation, application, and use of these glues.

O112.5-1.1

Scope This Standard covers unextended urea-formaldehyde resin adhesives, used for the bonding of wood in the manufacture of plywood and for other bonding of wood and some non-wood materials to wood where high strength and a moisture-resistant b ond are required.

1.2

Classification 1.2.1

Form of Adhesive The adhesive may be furnished as: (a) Liquid with separate hardener or catalyst; (b) Powder with separate hardener or catalyst; or (c) Powder with incorporated hardener or catalyst.

1.2.2

Types of Adhesives The adhesive shall be one of the following types: (a) Type I – Room-temperature curing adhesive; or (b) Type II – High-temperature curing adhesive.

Note: The proper application of these adhesives requires the maintenance of adequate pressure in conjunction with suitable temperature and himidity conditions for a sufficient time to effect a cure. For proper application, the manufacturer’s inst ructions should be followed regarding preparation, application, and use of these glues.

O112.6-1.1

Scope This Standard covers unextended phenol and phenol-resorcinol adhesives, and resins of these types used as a base for extended adhesives, to be used at temperatures above 85?C for the manufacture of plywood and other bonding of wood and some non- wood materials to wood, where a high strength, durable, wa terproof bond is required. This Standard does not apply to extended mixes of these adhesives as commonly used for the manufacture of hot-pressed plywoods, but does apply to the resins used as a base for these extended adhesives in which case, for test purposes, the resin shall form the base of an unextended adhesive as recommended by the manufacturer.

1.2

Form of adhesive The adhesive may be furnished as a liquid, powder, or film with separate hardener or catalyst, or filler, when required.

Note: The proper application of these adhesives requires the maintenance of adequate pressure in conjunction with suitable temperature and humidity conditions for a sufficient time to effect a cure.

O112.7-1.1

Scope This Standard covers phenol, resorcinol and phenol-resorcinol resin adhesives used for the bonding of wood at temperatures below 85?C for structural laminates, general construction, marine use, and other bonding of wood and some non-wood materials to wood, where a high strength and waterproof bond is required.

1.2

Classification 1.2.1

Form of Adhesive The adhesive may be furnished as a liquid with separate hardener or catalyst, or as a powder with separate hardener or catalyst.

1.2.2

Types The adhesive shall be one of the following types: (a) Type I – Room-temperature curing; (b) Type II – Intermediate-temperature curing.

Note: The proper application of these adhesives requires the maintenan ce of adequate pressure in conjunction with suitable temperature and humidity condition for a sufficient time to effect a cure. For proper application, the manufacturer’s instructions should be followed regarding preparation, application, and use of these glues.

O112.8-1.1

This Standard covers cross linking polyvinyl adhesives to be used in non-structural glued lumber products such as interior and exterior mouldings, window and door stock and glued lumber panels. This Standard is not an appropriate basis for evaluating the quality of glued wood products.
