How do you use Paraloid B72?

How do you use Paraloid B72?

Using a fine brush apply 20% weight/volume of B72 dissolved in acetone (i.e. 20g of B72 to 100ml Acetone) and allow to dry up to l5 minutes. On particularly rough surfaces a second coat maybe preferable to form an even surface on which to apply the marking.

How to prepare Paraloid B72?

Paraloid™ B-72 and its uses in Fossil Preparation When this solvent evaporates, the Paraloid™ itself is left behind, essentially plasticising whatever it is in contact with. If you need to get rid of it, it redissolves in solvent. Depending on the concentration of the solution, it can be used for a multitude of things.

How do you make Paraloid?

Paraloid B-72

1. Adhesive: 20-30% (grams/ml) in acetone or 1:1 acetone:ethanol up to 50% (grams/grams).
2. Consolidant: range from around 2% to around 10% (grams/mls) in acetone or ethanol. Or make up a 15% stock solution to dilute as needed.

How do you remove Paraloid b72?

Paraloid B-72 is more soluble in acetone than in ethanol; thus it may dissolve faster and form more concentrated solutions in acetone than in ethanol. Figure 3. An easy way to clean glass jars by soaking in water before the solution has evaporated and peeling out the residue.
