Mounting Adhesive 8 fl oz

Rublev Colours Mounting Adhesive is a professional quality adhesive that is water soluble so it can be thinned with water to extend drying time if desired. It dries to a water insoluble, strong and flexible film that is ideal for adhering and mounting canvas and paper to wood (i.e., hardboard, fiberboard, solid wood, etc.) and metal (i.e., aluminum composite material or ACM).

Rublev Colours Mounting Adhesive is made of VAE copolymer adhesive that has properties suitable for conservation use. It does not contain any formaldehyde, it has good dry tack, clear film clarity when dry and is non-crosslinking. Mounting Adhesive is solvent-free, and was specially formulated for preservation of materials, so it buffered to remain neutral pH, will not become brittle and does not yellow with age.

Background

In the early 1980s, the Canadian Conservation Institute (CCI) initiated a project to evaluate selected commercially available poly(vinyl acetate) (PVAC) adhesives for pH, emission of harmful volatiles, flexibility, strength, and yellowing upon dark and light aging. From this research, various adhesives were identified with desirable properties, but the vinyl acetate/ethylene copolymer (VAE) dispersions displayed the best, most stable properties. They were close to neutrality, released few harmful volatile products, were of medium strength, were flexible, displayed good resistance to yellowing and generally kept these characteristics upon aging. For example, the best VAE identified was Jade 403, a popular conservation VAE adhesive, but Jade 403 has an irritating odor and other properties that were deemed undesirable in this study.

To find an alternative to Jade 403, various VAE adhesives were subjected to a variety of comparison tests. Dry tack and flexibility were compared subjectively in a blind test by volunteer conservators at CCI who were asked to identify the dry adhesive film that was closest to a film of Jade 403. One of the VAE adhesives was chosen by the conservators (i.e., five of seven conservators chose it) as the closest to a film of Jade 403. Conservators also mentioned that they liked its handling properties in the wet state and that it had almost no smell.

VAE Copolymer Adhesives

VAE copolymer adhesives are usually water-based dispersions with 60–96% vinyl acetate content. VAE copolymers are as strong, machinable, and heat resistant as the PVAC homopolymers, and have better adhesion properties than the ester copolymers (e.g. vinyl acetate / dibutyl maleate).

Rublev Colours Mounting Adhesive is a VAE copolymer adhesive that has properties indicating it as the best choice among VAE adhesives for conservation use. It does not contain any formaldehyde, it has good dry tack, clear film clarity when dry and is non-crosslinking.
