PROTIM H1 is an effective preservative formulation designed to provide lasting protection for wood products used in internal situations above ground (hazard level 1 (H1)). The formulation contains an insecticide that is applied to timber by a controlled vacum pressure process.This provides lasting protection against wood borer (Anobium and Lyctid). Other formulations are available for H2 and H3 hazard levels PROTIM H1 also contains an effective combination of wax and resin that is designed to reduce the uptake of water by the timber during construction. This improves its stability by reducing the dimensional changes that would otherwise occur as water is absorbed and lost. PROTIM H1 uses a low odour, organic solvent carrier to transport the preservative into the wood. This solvent does not saturate wood cells and causes little or no swelling during treatment, unlike water-borne treatments. This means that the timber maintains its original size, shape and strength grading. PROT
