Shortens the drying of Mipa 2K-HS topcoats and Mipa 2K-HS clear coat CC 9. Especially recommended in winter at low temperatures. Greatly improves dry drying at room temperature without reducing dust drying time. This does not negatively affect the course. Leads to significantly faster curing even when oven is dried. By using Mipa 2K Reactive Additive VR in conjunction with Mipa 2K HS Hardener HS 25, the Mipa 2K HS Hardener HS 10 can be replaced or saved. Attention: The pot life is also reduced (by approx. 50%). Addition up to 20%, is used instead of Mipa 2K dilution.
