Characteristics
DINITROL 771 is a MS polymer-based adhesive with high green strength and is suitable for
making elastic constructive joints. Due to its high green strength, clamping times can often be
reduced or the requirement of clamps eradicated completely. DINITROL 771 can also be used as a
sealant, if similar materials (similar rigidity) are joined together or if mechanical fastening methods
are used.
- Solvent, isocyanate and PVC-free
- Very good UV-resistance and ageing properties
- In general, good adhesion on several substrates without the use of a primer
- Permanently elastic in a temperature range from 40°C to +120°C
- Neutral, odourless and fast curing
- Paint compatible with most industrial paint or lacquering systems, both alkyd resin and
dispersion-based (due to the large scale of different types of industrial paints, a paint
compatibility test is recommended)
- Paintable after skin forming (wet on wet); this will not influence the curing speed
Areas of Applications
- Elastic bonding and sealing in e.g. bus, train, caravan, camper and truck construction
- Bonding of windows in e.g. buses and trains
- Bonding of corner profiles of aluminium or polyester on trailers
- Bonding of polyester parts on metal frames
Method of Use
DINITROL 771 can easily be extruded with a hand or air pressure gun at temperatures between
+5°C and 35°C. In sealing applications DINITROL 771 should be tooled or smoothened within
10 minutes (at 20°C/50% r.h.) with a spatula or putty knife, and occasionally moistened with a soap solution.
Prevent the soap solution from penetrating between joint sides and sealant, given that this
will create loss of adhesion.
In bonding applications the substrates must be assembled within 15 minutes (at 20°C/50% r.h) after applying DINITROL 771. The higher the temperature, the shorter the open time will be!
In general, an adhesive thickness of 2 mm is recommended if similar materials (similar rigidity) are bonded. The larger the difference in thermal expansion, the thicker the adhesive bead should be.
For more details, please consult DINOL GmbH.
At a temperature of 20°C and a relative humidity of 50%, DINITROL 771 can be painted with most industrial paints just 10 minutes after application. Best paint adhesion is generally obtained if painted within 4 hours after applying DINITROL 771.
Cleaning tools or removing uncured DINITROL 771 residue can be done with a clean, colourless
cloth soaked in acetone or MEK. It is recommended to carry out a trial first to ensure that such solutions do not attack the substrate.
In general DINITROL 771 adheres well without a primer on clean, dry, dust and grease-free
substrates of aluminium, stainless steel, galvanised steel, zinc, copper, brass, powder coated
metal, most lacquered metal surfaces, glass, PVC, polyester (GRP), painted and lacquered wood,
etc. No adhesion on untreated polyethylene, polypropylene and teflon. In cases in which significant thermal or physical loads, especially under wet conditions, require high adhesion.
