Four other PVA adhesives, considered conservation standard by their manufacturer/retailer, were used in testing for comparative purposes. Tests were performed to determine the following; pH, Opacity, Off-gassing (Oddy test). A summary of the test and its results are detailed below:
pH
Arcare pH adhesive was tested to show a pH of 5.9 (with an accuracy of +/- 0.05 pH). The other adhesives tested ranged from 5.8 – 6.2. All of the adhesives tested were considered safe for use with organic materials.
Colour and Opacity
The range of adhesives were tested for their colour and opacity using a chromaticity meter. Cast at a thickness of around 1.5mm and dried to create a sample thick enough to register a reading (it’s accepted that this is much thicker than when actually used in conservation).
The image below recreates the difference in values provided by the test results using the L* a* b* values recorded (including the corrected background value).
Arcare PVA, although displaying an average colour change value of Eab 17.56 against a white background, was also one of the least opaque when measured against a black background. Combining the two figures gives an overall performance figure.
| Adhesive | Against a white background | Against a black background | Total |
|---|---|---|---|
| PVA 1 | 14.62 | 25.48 | 40.1 |
| PVA 2 | 13.24 | 31.21 | 44.45 |
| Arcare | 17.56 | 20.16 | 37.72 |
| PVA 3 | 13.95 | 19.82 | 33.77 |
| PVA 4 | 20.56 | 21.44 | 42 |
Oddy Test
The Oddy test is a qualitative test for off-gassing, performed by observing corrosion in three metallic tokens (silver, lead & copper) sealed in an oven over 28 days at 60°C. Each metal detects corrosion in a different set of corrosive agents and a ‘Pass’, ‘Temporary use’, or ‘Fail’ grade is applied according to the level of corrosion perceived.
| Adhesive | Silver | Lead | Copper |
|---|---|---|---|
| PVA 1 | P | T | T |
| PVA 2 | P | F | F |
| Arcare | P | T | T |
| PVA 3 | P | T | F |
| PVA 4 | P | T | T |
(P) Pass / (T) Temporary Use / (F) Fail
Of the five adhesives tested, Arcare pH neutral PVA adhesive was one of three which did not fail any of the tests.
Other Observations
Other qualitative observations made during the tests showed that, once dried, PVA 1 became brittle and shattered when cut with scissors. PVA 3 remained very flexible and was tackier than the other PVA samples after the Oddy test had been performed.
The results of the tests show that Arcare PVA is a consistently high quality adhesive which can be relied upon in a variety of applications.
Testing performed by Bainbridge Conservation – January 2016.

Paper is its own worst enemy. Most paper and card contains lignin, a natural source of acid from the wood used in the pulp. Acid will eventually cause the structure of the paper to break-down, becoming brittle and yellow. If the paper is already torn, this will be a weak point as that treasured item becomes older. It’s important to fix tears to prevent further damage and prevent the page from breaking into fragments. We advise taking the advice of a qualified conservator for repairs on any particularly valuable items.
You must not use anything other than an archival quality tape if you would like to repair a treasured item. Archival tape is acid-free, that includes the backing (known as the ‘carrier’) and the adhesive, so will not cause or accelerate the deterioration of the paper it’s applied to. Arcare archival tapes use a neutral pH acrylic adhesive that will not turn yellow or seep into the paper, it can also be removed (known as being ‘reversible’) by a conservator. You must never use normal sticky tape to fix a tear. Non-archival self-adhesive tape will dry out, leaving a nasty yellow residue on the paper that can’t be removed and will totally obscure and destroy any covered text or image.
For narrow repairs – Transparent mending tissue; or for wider repairs, or for a stronger repair – Document repair tape.

]]>This adhesive has been independently tested and approved for conservation use, read the test report here.
Excellent lay-flat properties this helps to keep curling or waves in the paper to a minimum and dries clear.
The easy to use polyvinyl acetate (P.V.A.) formula is fast setting, remaining tacky for long enough to be worked before drying completely.
This adhesive was formulated specifically for preservation materials, dries semi-clear and flexible and should not become brittle with age. Adheres to most surfaces. Can be mixed with Methyl Cellulose for a slower drying adhesive.
Three sizes available; 225ml, 950ml & 3.8L
