Hempel Thinners 845 (No 5) - 750ml

Hempel Thinner 845 (No 5) (08451) is a spirit-based solvent engineered to optimise the application of Hempel Light Primer and act as a heavy-duty tool cleaner for epoxy products. Formulated with paint conditioner technology, it improves brush flow and spray atomisation for a professional finish. It is not suitable for thinning polyurethane products or Hempel High Protect.

Hempel Thinner 845 (No 5) is a high-performance solvent diluent specifically formulated for use with two-component epoxy primers. While Hempel marine coatings are formulated for direct application when properly mixed, environmental variables or specialised application methods require controlled viscosity adjustment to ensure optimum film formation and adhesion.

Suitable for use with Hempel Light Primer 45551, this thinner allows coatings to be thinned for initial sealer coats, adjusted for thickened viscosity in cold weather conditions, or diluted during elevated ambient temperatures to prevent dry-spray. It also serves as an effective equipment cleaner for removing uncured epoxy residues from brushes, rollers, and spray apparatus. It is also suitable as a tool cleaner for Hempel High Protect 35651.

Add Hempel Thinner 845 (No 5) sparingly to the pre-mixed base and curing agent, stirring continuously until the required consistency is achieved. Thinning should always be kept to the minimum necessary amount to preserve dry film build, opacity, and coating performance. Always consult the specific product data sheet for maximum permitted dilution percentages prior to application.
