We use top-of-the-line IPA for manufacturing our SOL-640 IPA Based Cleaning Solvent for making sure the quality of product remains intact from the first usage itself. We suggest to make use of a brush for applying this solvent over the surfaces the user wants to. However, the mentioned product is majorly used to be applied on industrial soldering components. This SOL-640 IPA Based Cleaning Solvent is available in different packaging quantities as demanded by the customers.
