SOLUBILITY / THINNABILITY
In general, HTC Primer PU 725 has good compatibility with ethyl acetate, butyl acetate, 1-methoxypropylacetate-
2, xylene, Shellsol® A and Solvesso® 100. However, the solutions formed must be tested for their storage stability. Prolonged storage of a solution with low binder content may result in turbidity and sedimentation. Only PU grade solvents should be used (< 0.05 % water). The solvent should not contain reactive groups
PROPERTIES / APPLICATIONS
- Solvent-free moisture-curing one-component primers based on HTC primer PU 725 are suitable for sealing
concrete. - HTC primer PU 725 can also be used to formulate one-component systems for corrosion protection
applications. - It can be used to prime concrete, metal, and wood. It is an excellent all around concrete primer/sealer with
incredible adhesion.
STORAGE CONDITIONS
- Storage in original sealed HTC container.
- Exposure to sunshine should be avoided.
- Recommended storage temperature: room temperature (approx. 23 °C)
- Protect from moisture, heat and foreign material.
