70-07A is a solvent-free, low viscous, sprayable sealant based on Silyl Modified Polymer (SMP) with a special spray structure for sealing overlapping seams, welded seams and construction seams in automotive and coach work.
FEATURES
- Solvent-, isocyanate- and PVC-free
- Very good UV resistance and aging properties
- In general, good adhesion on several substrates without the use of a primer
- Permanent elastic within temperatures from -40°F to 212°F (–40°C to +100°C)
- Neutral, odorless and fast curing
- Paint compatible with most industrial paint or lacquer 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 cure rate
- Contributes to corrosion protection; does not attack metals
- By adjusting the spray pressure and nozzle, it is possible to obtain a rough or a fine spray structure.
APPLICATIONS
- Sealing of welded, overlap, and construction seams
- Overlaps of seams between PVC and metal
- For coating inside car wings, boots and bonnets and even as under-body coating
- As repair material in all above mentioned applications
- Sealing narrow seams and sealing small holes
- As a vibration reducing coating
