Novolac is a linear or branched polymer formed by the condensation reaction of phenol with an aldehyde. Resole is a three-dimensional, crosslinked polymer formed by the condensation reaction of a phenol with an excess of aldehyde in the presence of a base catalyst. Both novolac and resole structures contain aromatic rings linked by methylene bridges.

Some common solvents for novolac resins include acetone, methyl ethyl ketone (MEK), and toluene. These solvents are often used to dissolve novolac resins for various applications such as coatings, adhesives, and composites.
i make the phenolic foam out of both of them in the same formula it works out fairly well but i am engineering it to get top performance out of the polymers.

Epoxy novolac resin is a type of high-performance epoxy resin that is cured using a novolac hardener. It is known for its excellent chemical and heat resistance, making it suitable for demanding industrial applications such as in the coatings, adhesives, and aerospace industries. Epoxy novolac resins are often chosen for their superior mechanical properties and resistance to harsh environments.

The cost to resole climbing shoes typically ranges from 30 to 70, depending on the extent of the damage and the type of resoling needed.
DNS protocol.
In my point of view never use resole tyre for bike because thoes tyres are already useable and most of tyres are Worn out tyres.
30-100 bucks
About $45 to $75 depending on the shoe and where you live in the country.
Any good quality cobblers can resole any shoes for you.
