ACESOLVE PUN - 30L
Acesolve PUN is a solvent for general use in the removal of polyurethane and butyl-rubber based sealants from surfaces, transport facilities, rotating sealing tables and sealing machinery. Acesolve PUN is a slowly evaporating solvent. Compared to the fast evaporating solvent methylene chloride it offers the advantage of a longer treatment time. As Acesolve PUN also shows a strong solvent effect on plastics, paints and seals, we recommend a compatibility test prior to its large scales use. Teflon based materials (e.g. Kalrez* and Zalak*) are resistant seal materials; rubber and Viton may be attacked by Acesolve PUN. Acesolve PUN has been proved and released by well-known machine manufacturer.

Uncured sealant residues can be removed easily by Acesolve PUN. It can be also used to clean parts of sealant mixing machines (e.g. mixer tubes and pistols). The degree of cleaning achieved depends on the state of cure of the polyurethane sealant. Fully cured sealants will not be dissolved in any solvent, they will only swell. As Acesolve PUN evaporates very slowly, remainders of the solvent should be removed prior to use by either blowing out with compressed air or by base purging.
When using the product we recommend the use of suitable gloves. Safety instructions for the handling can be found in the Material Safety Data Sheet. Stored in well-closed containers at temperatures between 5 and 40 °C the minimum shelf life of Acesolve PUN is 1 year.
