UHU HART Balsa Cement 35G

UHU Hart Balsa Cement and Model Making Adhesive

The Crystal-Clear Fast-Setting Nitrocellulose Adhesive for Rigid Wood Assembly and Joint Reinforcement

UHU Hart is a premium, crystal clear, fast drying nitrocellulose adhesive engineered specifically for precision model making, high fidelity crafts, and detailed structural hobbies. Widely recognised as the industry standard balsa cement, it excels at bonding balsa wood, plywood, and other porous wooden materials, as well as fixing accent elements made of metal and various plastics. Its unique chemical composition ensures rapid assembly times, allowing hobbyists and architectural model makers to construct complex frameworks with complete confidence.

Key Performance Features

• Rigid Hard Film Finish: Unlike flexible general purpose glues, this specialised adhesive dries to a tough, completely rigid finish. This makes it perfect for structurally reinforcing weak or vulnerable joints, and for stiffening or sealing porous material surfaces against stress.
• Precision Applicator Nozzle: Each tube includes a fine tip nozzle accessory specifically designed for the neat, tidy, and controlled assembly of microscopic or delicate components without messy overspill.
• Fast-Setting Efficiency: Formulated for quick initial grab, reducing the need for extensive clamping when building intricate architectural trusses, model aircraft wings, or miniature scenery.

Material Compatibility Guide

• Ideal for: Balsa wood, hardwoods, birch plywood, paper, dense cardboard, greyboard, model making metals, and a wide array of hard plastics utilised in scale kit manufacturing.
• Surface Requirements: To guarantee an unbreakable mechanical bond, ensure all mating surfaces are completely dry, clean, and free from workshop dust, sanding residue, or manufacturing grease.

Professional Application Methods

• Standard Porous Application: Apply a thin, uniform layer of adhesive to one side of the assembly. Immediately place the parts together, align them precisely, and hold them firmly in place for a few moments while the initial bond forms.
• The Dual-Coat Method for Hard Enclosed Surfaces: When joining dense or non porous materials, apply a thin layer to both sides of the joint and allow the adhesive to dry. Re apply a fresh, thin layer to one side, press the parts together immediately, and hold securely.
• Workshop Clean up: Remove fresh, wet glue stains as soon as possible. Once cured, this high strength nitrocellulose adhesive residue cannot be dissolved safely and can only be removed mechanically by scraping or sanding.

Alternative UHU Product Recommendations for Difficult Materials

Because UHU Hart dries via solvent evaporation into a rigid film, it is not chemically compatible with specific synthetics. If your project involves these difficult materials, please utilise these specialised alternatives within the UHU range:

• For Styrofoam and Expanded Foams: UHU Hart contains active solvents that will instantly melt expanded polystyrene. For Styrofoam, EPS, EPP, or EPO foam models, utilise UHU POR to achieve a clean, incredibly strong, and completely foam safe bond.
• For Low-Energy Plastics (Polyethylene and Polypropylene): Industrial plastics like PE and PP naturally resist liquid adhesion. To create permanent structural joints on these sleek materials, utilise the multi part UHU All Plastics Adhesive system to chemically prepare and weld the plastic interfaces.
