- Product Enquiry
Unigrip 999 HR (Hydrolysis Resistant) grade is an economic polyurethane adhesive specially formulated for use in applications requiring water immersion for PVC inflatable boats.
The product provides excellent adhesion for footwear and a wide variety of soiling substrates exceeding all LASRA requirements.
Unigrip 999 is specially stabilised against excessive and early yellowing and staining due to sunlight.
When used in marine conditions such as PVC inflatable boat repairs, Unigrip 999 HR must be used with cross linking agent Desmodur RFE
Unigrip 999 will bond any of the following:
- PVC or PVC/rubber blends
- resin and microcellular rubbers
- other rubbers
- thermoplastic rubber
- natural or reconstituted crepe rubber
- microcellular EVA
The use of the cross linking agent Desmodur RFE dramatically improves adhesion for use in PVC inflatable repairs and provides bonds with much higher heat, solvent and water resistance.
Mixing ratio: 20 parts Unigrip 999 HR to 1 part Desmodur RFE
Not suitable for: polyethylene (hypalon), polypropylene, Teflon and polystyrene foam
All surfaces to be bonded must be clean and free from contamination. We recommend wiping with Bostik Solvent #2 (Toluene) or #4 (MEK/Acetone) to clean the surface. Where practical, surface roughing will give a higher bond strength, some surfaces may need priming.
In all cases consult the most current Technical Data Sheet and Safety Data Sheet at www.bostik.co.nz, or contact Bostik for a copy.
NOTE: Some substances may require primers.
