Product features and applications
Titebond Multibond SK-8 is an exceptionally strong, water-resistant D4 industrial wood adhesive for interior and exterior use. The single-component PVA emulsion is designed for solid wood joints and laminating. Suitable for hardwood, exotic timber, furniture components and skateboard manufacturing with an appropriate pressing process.
Impressive bond strength of approximately 304.4 kg/cm². In the manufacturer's ASTM D4317 test on dry maple joints at +24 °C, the average shear strength was 4329 psi (approximately 29.8 MPa).
- D4-class wood adhesive
- For hardwood and exotic timber
- Single-component system
- For laminating and solid wood
Application and preparation
Stir thoroughly before use. Minimum application temperature: +7 °C. Moisture resistance does not replace surface protection for exterior timber.
Where is Multibond SK-8 used?
Designed for industrial assembly of wood products, edge and face joints, and laminating. The manufacturer highlights skateboard production and cold, hot and radio-frequency pressing. Select suitable surface preparation and pressing conditions for the particular timber and product.
Water resistance and bond strength
SK-8 meets ANSI/HPVA HP-1-2000 Type 1 and ASTM D-4317 Type 1 Wet Use requirements. D4 does not mean unlimited resistance in all outdoor conditions: long-term performance depends on the product's design, timber, protective coating and correct bonding.
Existing laboratory test data are provided below. Assess them alongside the test method and materials rather than as a guaranteed strength for every joint. Read the technical and Safety Data Sheets before use.
Laboratory test data
Results were obtained under the specified test conditions and are not a guarantee for every bonded joint. Joint strength depends on the wood species, surface preparation, adhesive quantity, pressing and temperature.
